Improving the Quality and Safety of BMS

Zero carbon emission has vastly become a worldwide trend as the popularity of electric vehicles (EV) begins to grow; the battery is being the key component. The performance and safety of battery packs is critical to the EV; its core battery management system (BMS) needs to be thoroughly verified to ensure the battery’s safety.

▲ Chroma 8710 EV / Bus BMS ATS

Chroma 8710 BMS ATS provides battery cell voltage and temperature sensor simulation for battery management system; furthermore, it offers applications suitable for testing the UUT (unit under test) to reduce the problems when performing the tests. The inspection functions equipped by the system include:

  1. The BMS circuit designed power conversion circuit converts the starting battery voltage to the power required by digital circuit. It is necessary to confirm the power status to make sure that the control circuit works stably.
  2. Measurement accuracy is required when using high voltage to measure the battery pack total voltage. This voltage is also one of the judgment criteria for enabling insulation resistance. The inspection of insulation resistance is critical to safety requires verification. Besides supporting the verification, the best way is to perform calibration first and verification later.
  3. The high/low side drive circuit controlling the high voltage relay is also one of the vital items for verification. When an error occurs, if the high/low side gate drive circuit is not active to disconnect the charge and discharge circuit, it could cause safety problem and result in burning the electric vehicle. Therefore, it is necessary to check if the high/low side drive circuit is running normally under all kinds of conditions.

Chroma has in-depth research on battery management system that makes the 8710 BMS Functional ATS capable of fulfilling the above test requirements to perform a fully automated test procedure and long hour battery pack charging/discharging test.

A battery management system usually comprises of a current sampling unit (CSU), a cell supervisory circuit (CSC), and a battery management unit (BMU) via CANbus to transmit signals and issue commands for operation. When verifying a battery management system, it is imperative to verify the cell status monitored by CSC as well as the active/passive balancing circuit and current consumption. For CSU, the validation of current sampling accuracy is essential as it may affect the battery SOC, SOH and overcurrent protection. As to the most complicate BMU that controls the entire system, it verifies the data returned from CSU and CSC.

Integrating with the test systems customized by Chroma can perform high quality functional verification on battery packs and battery management systems with provision of applications suitable for testing the UUT to reduce the trouble occurred during testing.

It supports active and passive balancing circuit tests in 0~5A and 0~500mA two current ranges with measurement accuracy up to 0.02%F.S. For 0~5A range (power increase when paralleled), the accuracy is up to ±1mA with resolution up to 100uA that can meet the active balance design circuit test requirements. For 0~500mA range, the accuracy is ±100uA (0.02%F.S.) with resolution up to 10uA that can meet the passive balance design circuit test requirements. It is suitable for BMS circuit boards for measuring battery cell current consumption.

Significantly Reduce BMS Verification Costs

Certainly, the battery management system can also be used to verify the battery cell; however, it cannot maintain the same characteristics for repeated tests due to the influence of temperature, charging and discharging speeds, aging degree, and efficiency, etc. Moreover, setting up too many battery cells in the laboratory could raise safety concerns. In the past, the engineers connected several DC power supplies in series on their desk to test the cell supervision circuit (CSC) by manually adjusting the voltage and parameters, which took time and space, and the functions can be tested were limited. Using the Chroma 87001 Cell Simulator for testing became the better solution.

Chroma Launches Its New 63000 Series DC Electronic Loads to Satisfy the Tests for Small Power Supplies and Batteries

Chroma 63000

To meet the testing requirements of small power supplies, Chroma has launched a brand new 63000 Series of benchtop DC electronic loads specifically designed for testing lower power adaptors, cell phone chargers, small batteries (such as cell phone batteries), D/D converters, USB PD, and so on. Different from the modular electronic load, they can be used without a mainframe. With the advantages of its compact size, lighter weight, low cost, and portability, the 63000 Series is the perfect electronic load for R&D labs and colleges.

 Chroma 63000

The voltage and current specifications of each model in the 63000 Series are comprised of three settings and three measurement ranges. For adapters and USB PD’s that require higher testing accuracy, small current test like 0.1A is often performed during efficiency testing. However, misjudgment frequently occurs due to insufficient range or low accuracy. The minimum setting and measurement current range of the 63004-150-60 is 2A and the current error is less than 2mA which makes it suitable for these tests and validating the regulatory compliance of Energy Star. The maximum current output of a single load is up to 60A, with power up to 350W. Besides, the large scaled fonts and moderate shortcuts in its 3.5” LCD display bring great usability in the forms of sight and touch.

Chroma 63000 LCD screen

In addition to the basic CC, CR, CP, CV, and CRD modes, the 63000 Series also has battery discharge, User Defined Waveforms (UDW), and programming functions to satisfy the test requirements for D/D converters, 3C battery dischargers, and switching power supplies.

The battery discharge mode is applicable for 3C battery discharge test and can record the Wh (Watt) and Ah (Ah) during battery discharge. The User Defined Waveform (Figure 1) can simulate the real load current allowing the R&D test engineer to verify the power in the actual load current. The quality assurance department can reproduce the actual load current situation to reduce the development and validation time. For other DC power and component applications such as fuel cells, fuses, switches, and wiring tests, the pulse current (Figure 2) function is provided to test them by setting the repeat time to 1 in the existing dynamic loading mode.

Advanced Test Solution for New Energy Parts – Chroma Multi-Channel Battery Simulator

Chroma ATE Inc. was invited to attend the IFEEC 2017 (International Future Energy Electronics Conference) held in Kaohsiung to introduce the new product for battery simulation. The battery simulator can perform simulations on the units that are critical to the booming EV industry such as DC charging pole, on-board charger, and DC/DC Converter, etc. for product verification.


Battery Simulator Soft-panel

As more and more energy conversion products such as motor driver, OBC, DC/DC convertor, and power conversion system (PCS), etc. use battery as the power source, a battery simulator is required for product quality verification. Battery suppliers may not be able to supply batteries of various kinds such as flow battery, sodium sulfur storage battery, and lithium-ion battery with different charge/discharge characteristic curves during product development.

The battery characteristic is nonlinear which is easily affected by temperature, charge/discharge current, aging cendition, and efficiency ,cannot replicate the same characteristic for repeat testing. As time is required to charge or discharge a battery, it makes instant output voltage change impossible for the real battery, which is quite inconvenient when testing the power converter’s upper and lower limits. Most importantly, the large capacity battery is big in size and will age after long-term use. It costs a lot for replacement, plus if the battery is damaged, overcharged or over discharged. It could easily cause safety hazards. In the lab, it is not recommended to set up large capacity batteries, but rather to use a battery simulator for testing.

What functions are required for a battery simulator?

  1. Battery internal resistance setting: The main task of a battery pack is to provide energy to the developed products. When the charged/discharged current is added to the battery pack, the voltage of the battery pack changes instantaneously in a short time due to the impact of the battery internal resistance.
  2. Battery capacity setting: The DC input voltage operating range should be clearly specified in the developed product specification, which is related to the battery pack capacity and output voltage.
  3. Battery voltage point setting: The usage of the battery pack varies with products, and the frequently seen battery management items are 6 voltage level including overcharge voltage, over discharge voltage, upper limit operating voltage, lower limit operating voltage, full charge voltage, and full discharge voltage.

Chroma’s multi-channel battery simulator is easy to use. The multiple embedded channels can test different DUTs at the same time, and read the test results in real time. The rapid setup of common battery parameter can simulate the charge/discharge voltage and IR state of a battery cell under normal, high and low temperatures. The battery cell parameters can convert battery pack state to set the operating and protection range. Moreover, it can set the initial state of output voltage for product testing and verification without waiting for the charge and discharge time like the real battery pack.

It also has features of high response speed and high sampling frequency with adjustable voltages providing -5V~+5V, 0 ~ +5V and 0 ~ 10V three measurement ranges for selection that can be widely used in half battery / battery cell, super capacitor and lithium ion capacitance tests. Operating with Chroma’s powerful Battery Pro software, the tester enables the user to perform material analysis, performance testing, dynamic waveform simulation and specification screening on the DUT.

Battery Cell Insulation Test

The traditional insulation test of a battery cell is to measure the leakage current in the final testing phase to determine whether the internal insulation is good. However, it does not detect if partial discharge has occurred during the entire testing process. Chroma 11210 Battery Cell Insulation Tester performs partial discharge detection during the Charge – Dwell – Test process, and then integrates with the final leakage current measured results to evaluate the battery cell’s internal insulation status. The tester allows the user to use the partial discharge phenomenon that occurred during the testing process as criteria for determining the battery cell quality.

The Newest High Voltage Photovoltaic and Microgrid Test Solution

The development of photovoltaics and microgrids are heading towards distributed photovoltaic power generation and energy storage / smart inverter systems. Commercial photovoltaic power generation and energy storage requirements are growing fast and demanding grid-connected high voltage 690Vac / 800Vac systems to reduce the cost of AC wiring and improve the efficiency of power generation system.

Semiconductor test has evolved to a level of safety, responsibility and reliability. The IC quality is absolutely important for self-driving cars because it concerns personal safety. When the car is driving in different environments, the temperature can change from high heat to freezing as well as high winds and rain all make the IC chip’s reliability a necessity. Moreover, for new applications, such as in VCSEL 3D image sensing, it has to be sure that it is no harm to people. All of these new applications provide a challenge to chip manufacturers and test equipment manufacturers for their ability to keep the car safe for drivers.

This means that semiconductor test equipment manufacturers need to work with customers earlier in the design process. Chroma ATE has been a Turnkey Solution provider with core technology in measurement since 2011, and is the only manufacturer equipped with testing and automation capability. Chroma’s products are mainly used in communication (FPD, color and video, optical components, power electronics, passive components, electrical safety, thermoelectric temperature control and automatic optics), semiconductor/IC, and clean technology (EV, green battery, LED lighting and solar energy) industries to effectively improve the quality of customer products and production efficiency in helping customers enhance their competitiveness.

Chroma has many product lines to fulfill the needs of semiconductor testing by supplying various kinds of equipment from R&D to mass production such as large ATE test systems, sorting machines and compact PXI test platforms, all of them have complete corresponding products to give customers the most appropriate selection. The complete semiconductor solution of Chroma covers different wafer test applications including consumer chips (microprocessors, audio chips, computers/mobile peripherals, etc.), power chips (linear regulators, DC converters, AC converters, LED drivers, etc.), radio frequency chips (wireless network, blue, blue, etc.), power chips (such as microprocessors, audio chips, computers / mobile peripherals, etc.), RF chips (wireless network, Bluetooth, mobile communication, etc.), and chips for specific testing areas (image sensors, radio frequency identification, etc.)

New IoT applications Initiate comprehensive semiconductor testing needs

Internet of Things (IoT) digitizes the real world by narrowing the scattered information and consolidating the digital information of things. It has a broad market and application prospects that is structured in three layers; sensing, network and application. Ranging from logistics and transportation, health care, smart environment (home, office and factory) along with personal and social areas, almost anything can be closely related to IoT. The IoT chip has been widely used in network and various types of sensors. For different applications in a test environment, the way to ensure that each IC’s function, performance and quality meet the standard is specifically important. Chroma’s Semiconductor BU general manager, George Chang, indicated that to cope with diversified applications, semiconductor wafer testing must incorporate a variety of test items including temperature, radio frequency (RF), precision and speed, to meet all types of IoT applications and customer needs.

Chroma provides complete semiconductor test solutions including SoC / VLSI/ Analog test solutions, IC test handlers, PXI IC test platforms and equipment corresponding to various types of IoT applications in testing embedded processor, MCU, RF MUC, Light Sensor, Magnetic Sensor, G-Sensor/Gyro, CMOS Image Sensor, Finger Print Sensor, Laser Diode, PMIC), and diversified wireless network implementation.

The widespread use of IoT creates a huge demand for micro control units and sensors, which lead to fierce competition in cost and production. As electronic products are always aiming for high cost-performance ratio with better functionality, Chroma is capable of providing competitive test instruments that are flexible to integrate with other equipment and automated systems to meet the demands for increased testing requirements and cost savings.

AI, smart driving, system level and burn-in test ensure final quality of IC

In light of the evolution of semiconductor process and packaging technology, the capabilities of ICs used in consumer electronics, automobiles, internet of things and artificial intelligence are getting more powerful with increased packaging density. Herbert Tsai, the ISS BU deputy general manager of Chroma ATE Inc. pointed out that for the complex packaging products such as SoC/SIP/3D ICs, besides inspecting the power and signal through traditional automated test equipment (mixed single ATE), the System Level Test (SLT) and Burn-in (BI) inspection process are also applied to do a comprehensive testing on IC to ensure its final quality.

As the IoV (internet of vehicle) and smart driving are growing trends, many car manufacturers have implemented ESC (electronic stability control) systems to receive and send signals through the sensor, camera, lidar and RF equipped on the car. When the system has collected the information from each component, it will quickly analyze and evaluate the vehicle status, and give commands to correct the steering wheel, slow down, brake or alarm. This means the system must have powerful semiconductor components to support the overall operation. These automotive systems have to remain in normal operation even under extreme conditions as they are related to driving safety. For varied driving environments, the demand for tri-temperature system level testing (Tri temperature SLT) on car chips is rapidly emerging. The product quality of car chips can be assured after rigorous and long-hour high/low temperature testing.

In recent years, the development of AI chips has been the frontline of first-tier manufacturers. The development of artificial intelligence at this stage is based on parallel computing technology and the depth of deep learning. Through the robust capabilities of self-learning and computing inside the chip, the equipment or systems are able to react properly in time. However, these types of high level chips (GPU/FPGA) are very expensive with strict quality demands, and passing through long hours of SLT/Burn-in test is the way to guarantee that every chip can operate normally under high temperature and high voltage environments.

Chroma has been dedicated to FT / SLT Handler technology research and development for a long time. In addition to the desktop equipment for the design house, Chroma also provides multi-functional and efficient test equipment for designers to use. Moreover, Chroma has introduced multi-probe tri-temperature test equipment to satisfy customer’s demand for mass production. The test technologies proprietary to Chroma can also be customized to meet customer needs providing the best test solutions.

 

Chroma Developed an Exclusive Motor Controller for Smart EV in Taiwan

On August, 29, 2017 the general manager of Chroma’s Integrated System Solution BU, I-Shih Tseng, was invited to present the research and development results on HAITEC (Hua-chuang Automobile Information Technical Center Co., Ltd.) vehicle platform in “Taiwan Automotive Technology Innovation and Development Summit.” I-Shih expressed that reducing carbon emissions is a common goal for countries around the world, and Taiwan cannot remain on the sidelines. Today’s focal point, LUXGEN S3 EV+ is a 100% self-developed smart electric vehicle as a pioneer in reducing carbon emissions in Taiwan.

 

The global sales of electric vehicles were up to 774,000 units in 2016, up 42% from 2015. Lately, many countries have started to put forward EV related policies. For instance, Norway took the lead to set up the goal of fully electric cars on the market in 2025 while Britain and France announced that they will ban the sale of new petrol and diesel cars from 2040. In response to these policies, the international automakers have set up strategies to deal with these changes; for example, Volvo announced in July that all its car models launched after 2019 would be electric or hybrids.

HAITEC has been actively involved in the development of electric vehicles in recent years. Through the collaboration of industry, academia, and government, an ecosystem team encompassing motor, controller, battery, on-board charger and other key components manufacturers was formed to successfully create a Taiwan developed a smart electric vehicle. I-Shih also pointed out that the city S3 EV+ was developed suitable for Taiwan terrain and traffic condition as a smart energy passenger car with a speed dial b-Paddle. It is equipped with regenerative braking function to save energy when driving on the road, with power consumption of only 130Wh per kilometer. It can also be used as a mobile energy storage system (ESS) to integrate with micro-grid for household emergency use.

In electric vehicle powertrain system, Chroma is dedicated to developing motor control unit (power inverter). We aggressively cooperate with HAITEC to develop the controller exclusive to S3 EV + with power up to 150kW, efficiency up to 97%, and power density up to 15kW per liter. For the most important indicators of a vehicle – reliability and safety, Chroma’s motor control unit has passed the automotive level verification tests to be in compliance with international level quality.

At last, I-Shih expressed the appreciations to the consortium members, including Industrial Technology Research Institute, Automotive Research and Testing Center, National Taiwan University, Taiwan University of Science and Technology, and Taipei University of Science and Technology for their great efforts in completing the electrification of powertrain that was successfully been integrated in Taiwan’s first self-developed S3 EV+ smart electric vehicle, and making the automobile industry moving towards a whole new milestone.
