Power Battery PACK Test System

WBTS Series

The WBTS series power battery PACK test system has been specially developed for power battery pack charging, discharging, working condition simulation,and other tests. Adopting core technologies such as four-quadrant PWM rectification, bidirectional BUCK conversion, and pure digital control, it has the main features of bidirectional energy flow, 100% energy feedback, high accuracy, rapid transient characteristics, high conversion efficiency, low pollution to the electrical grid, rich communication interfaces, and robust protection functions. lt can realize AC-DC conversion to charge the power from the grid into the battery module, and it can also feed back the power discharged from the battery module into the grid in the form of the grid-connected inverter so that the part of power can be recycled and reused. The device is a bidirectional power feedback type battery charging and discharging power processing system controlled by computer background software.

Product Features

Adopting four- quadrant PWM rectification technology, high power factor, and small harmonics.
Power factor>99%, harmonic distortion rate<3%, small impact on the electrical grid.
DSP high- performance processor, realizes complete dual closed- loop feedback control, safer and more stable.
Independent air duct design improves the adaptability of the equipment to harsh environments.
It can be operated offline, and the equipment with a touch screen and storage unit can operate independently.
Modular design: each module operates independently, is easy to maintain, and has centralized management and control.
Flexible configuration: customize charging and discharging equipment with different channels and powers according to customer requirements.
Channels can be used in parallel, convenient for customer expansion and improve production efficiency.
Integrate with other equipment or devices (such as constant temperature box, vibration table, voltage, temperature acquisition system)
The software can conveniently and quickly realize data docking and control with BMS through the CAN communication protocol (.DBC file) provided by the user.
Complete functional tests: capacity, cycle life, rate characteristics, HPPC, charge and discharge efficiency, DC internal resistance test, working condition simulation, and other performance tests.
