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).
