A Productive Utility for New Energy Vehicle LV123 Standards Tests Chroma High Voltage DC Power Supply Test Software

Complying with global energy conservation trends and policies driven by international governments, many automakers have released technical development standards for next generation vehicles, which define various electric vehicle tests for hybrid, plug-in hybrid and fuel cell vehicles. Chroma has integrated these regulatory requirements aiming to provide users with specialized and convenient test programs making Chroma a productive partner for testing new energy vehicles.

The test requirements of LV123 are defined by major European carmakers to test the electrical characteristics and safety of high-voltage components in road vehicles, such as HV battery system, inverter, electrical air conditioning compressor, electrical transmission oil pump, DC/DC converter HV/LV and On-board charger, etc. This standard defines the state and operating capability of each voltage range.

The LV123 standard regulates different states for voltage range from 0V to 800V, as shown in the table below, and demands rapid voltage slew rate change. Chroma’s 62150H-1000 DC power supply supports 0-1000V voltage output with up to 40V/ms slew rate control and can meet the LV123 basic electrical characteristics requirements through the test items listed below providing the best solution for testing new energy vehicles.

The Newest Electrical Mains and Power Line Interference Simulation Testing Software for Download

In recent years, renewable energy has received lots of attention in particular the huge growth of solar energy and wind power. More and more power systems incorporating into the grid could have a significant impact on the current power system. Thus, many standards were set up for integrating renewable energy into the grid such as UL 1741, IEEE 1547, IEEE 1547.1, and NBT 32004, etc.

Moreover, the Low Voltage Ride-Through (LVRT) feature put forward by various countries stipulates that the grid-connected device such as a solar inverter or wind power generator will continue to supply power, when the grid voltage falls, for a period of time until the grid power returns to normal.

To address these requirements, Chroma has released testing software that can simulate the abnormality/distortion of the electrical mains and power line interference. This graphical human-machine interface software controls Chroma’s regenerative grid simulator, the 61800 Series, which is equipped with four quadrant capabilities to satisfy test demands.

In the example below, the power dropped to 0V for 150ms and resumed 70% of output for 550ms, and then spent 800ms to rise from 70% to 90% output capacity. All these conditions can be easily simulated using the software LIST mode. In addition, a preview of the waveform can be seen on the software.

61800 Softpanel

Chroma’s AC Source Software has functions for , LIST mode, STEP mode, PULSE mode, and User-Defined Waveforms (to simulate distorted or interfered mains power). Also, the inter-harmonic test function can simulate the abnormality of the main electrical power.

Screenshots for the software are shown below:

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.

Chroma ATE Invested Innovative Nanotech Inc. with Technology Transfer from ITRI to Advancing in Semiconductor Front-end Process Inspection

TAOYUAN, Taiwan, Nov. 24, 2017 — Innovative Nanotech Inc., invested by Chroma ATE Inc., signed a contract with Industrial Technology Research Institute (ITRI) on Nov. 24 for “Nanoparticles Monitoring Technology” transfer. In addition, ITRI will serve as an important shareholder of Innovative Nanotech. Just a short time ago Innovative Nanotech had been contracted with Hsinchu Science Park for the purpose of developing and creating liquid nanoparticle monitoring systems used in the semiconductor manufacturing process to help improve the yield rate.

Figure:Chroma ATE Inc. CEO Leo Huang (right) signed a contract with Industrial Technology Research Institute (ITRI) on Nov. 24 for “Nanoparticles Monitoring Technology” transfer to Chroma’s new startup company, Innovative Nanotech Inc.

Large amount of liquid solutions are often used to clean, grind and etch the wafer surface during the semiconductor manufacturing process and impurities in the solution have an impact on the defect rate. Light scattering particle measurement technology currently cannot precisely detect the size and quantity of solution particles under 20nm, which makes it difficult in controlling the manufacturing process. Also, with development from 20nm to 10nm and even to 7nm, the minimized transistors make the width of current path narrow; therefore, when impurities like nanoparticles appear in solution, it will affect the defect-free rate of the product.

Innovative Nanotech will introduce to semiconductor manufacturers a new generation nanoparticle monitoring system, SuperSizer, which will accurately detect the size and quantity of particles above 5nm. This will allow manufacturers to take necessary measures to improve the process according to the monitored results. In addition to the semiconductor manufacturing process, this technology can also be applied to electronics, optoelectronics, and biomedical materials fields.

Innovative Nanotech will expand to a global market by incorporating the sales and marketing channels of Chroma group.
