Best Choice for 48V Power System Testing Brand New 100V DC Power Supply with Auto-Ranging Output 10kW~150kW

As the trend for global energy conservation and carbon emission reduction leads the evolution of new energy vehicle electrical systems, the world’s major car manufacturers have proposed 48V power system and LV148 regulatory standards for testing new vehicles. Comparing to the previous 12V power system, 48V power system has higher conversion efficiency and increased stable start-stop performance. In addition, the server power supply structure is also moving from conventional 12V to 48V in order to optimize the overall system power conversion efficiency.

Chroma launches a new 100V DC power supply, Model 62150H-100P, with auto-ranging output feature to support 40V/50V/60V/…/100V voltage ranges and output up to 15kW full power. It is suitable for testing products with different specifications such as the 48V new energy vehicles from 0V to 60V and the 48V architecture for server power and telecom power. The DC power supply is able to output the power from 10kW up to 150kW when setup in parallel under master/slave structure. It has active current sharing and fast transient response functions with active PFC to put low energy consumption and high conversion efficiency into effect to save energy.

High Accuracy and High Stability
The voltage control accuracy on the front panel and through the communication interface is up to 0.05% allowing users to set the required output. The stability of constant voltage and current is 0.005% for 8 hours operating. The temperature coefficient of drift is 0.005%/°C that provides an accurate and stable power source steadily even after long hours of operation.

Voltage/Current Slew Rate Control
The DC power supply’s voltage slew rate control is from 0.001V/ms to 5V/ms and can integrate with an automatic programming mode to meet the diversified needs of specific applications such as automotive electronic systems. Chroma incorporates the ISO 16750-2, VW 80000 and GS 95024-2 international automotive electronics standards into the GUI, Softpanel, to help users speed up the development and testing task.

Chroma’s 17040 regenerative battery pack test system reduces power consumption and provides dual modes for battery charge/discharge test and battery simulation to test battery connected devices.

Chroma ATE Inc., a leading provider of power conversion test equipment, announces the release of the 17040 Regenerative Battery Pack Test System. The 17040 test system is a high precision system specifically designed for secondary battery module and pack tests as well as battery simulation. It has a regenerative function to greatly reduce power consumption during discharge and ensure a stable power grid without generating harmonic pollution on other devices even in dynamic charge and discharge conditions. It is capable of recycling the energy discharged (Eff. >90%, PF >0.95, I_THD <5%) back to the grid reducing wasted energy that is discharged traditionally in the form of heat resulting in reduced HVAC requirements. The 17040 is available in four voltage (up to 1,000VDC) and current ranges with auto ranging, high accuracy current/voltage measurement (±0.05%FS/±0.02%FS), 2ms current slew rate, and 1ms data acquisition.


Chroma’s 17040’s also have built in parallel channels and dynamic profile simulation functions. The parallel capability increases the charge and discharge current and power to its maximum, increasing its efficiency and flexibility. The dynamic profile simulation allows the user to load a battery waveform of a given drive profile in either current or power mode to meet NEDC/FUDS requirements. Its bi-directional architecture ensures that current will not be interrupted during the charge and discharge transition state so it provides an accurate simulation of driving conditions in line with ISO, IEC, UL and GB/T international testing standards.

The Battery Simulation mode is featured to test battery connected devices. When a connected device is under development, the 17040 can simulate the battery to verify whether or not the device is functioning as designed. In addition, the 17040 can control the SOC status of different batteries. Users can upload required battery curves to test the DUT for charge and discharge status. The 17040 can also perform battery and DUT collocation evaluation tests in advance that apply to the motor driver for vehicle start-stop systems, light EV electronic controllers, car mounted chargers, etc.

Multiple safety features are built in to the system including Over Voltage Protection, Over Current Protection Check, Over Temperature Protection, and external parameter detection to ensure protected charge/discharge testing on the batteries. Additionally, data loss, storage and recovery are protected against power failure.

Chroma’s Battery Pro software provides users with flexible test editing functions to perform independent channel tests, detailed reports in customizable formats, and abilities to meet various requirements of battery packs with high safety and stability. Software/hardware integration and customization capabilities include BMS, data loggers, chambers, external signals, and HIL (Hardware in the Loop).

Chroma’s Battery Production Line Automated Test Solution Adopted by Famous Automotive Manufacturers in China

Chroma ATE Inc. is a world leading supplier of precision Test and Measurement Instrumentation, Automated Test Systems, Intelligent Manufacturing Systems, and Turnkey Test and Automation Solutions. In recent years, Chroma has been actively cultivating the electric vehicle (EV) testing market, and its newly launched lithium battery pack end-of-line (EOL) automated test solution has been successfully adopted by several of China’s well-known automotive manufacturers. Our solution provides safe, real-time monitoring of the test process and saves up to 6 times the inspection time, significantly reducing the production cost.

Once an automotive manufacturer completes the selection of battery cells and battery pack design, as well as development, it then faces bottlenecks in cost and speed during the process of mass production. The safety of EV battery pack production must be taken seriously as the process encompasses potential danger of high voltage and high energy density. Using an automatic battery inspection system can reduce production costs and improve the throughput effectively, and also ensures the safety of the entire fabrication process. Moreover, manual tests can cause inconsistent results, handwritten data errors, long testing hours, product traceability problems and more. At present, automotive manufacturers request that the EOL test for the finished battery packs before shipment takers 10 ~ 20 min/pcs with real-time monitoring, automatic reporting of traceability, and security protection mechanisms. Hence, the modular and automated test solution has been gradually adopted by many automotive manufacturers for battery production.
