Charge and discharge testing equipment

BOS series of energy feedback power battery performance detection system is a computer-controlled two-way high-precision DC power supply processing system. The user can set certain parameters for the energy flow between the grid and the load for flexible control. The system is specifically designed to test the power battery pack and its subsystems.

The system can include a variety of DC load, including battery performance testing。 Compared with the traditional power supply, the system can provide more testing。 The system uses energy feedback structure, can discharge the energy of the battery without external resistive load to the grid or directly transferred to the need of charge the battery to solve the traditional resistance-type discharge energy dissipation and workshop heat dissipation。 In addition, the system can also meet the specific needs of users of a variety of products through the integration of specific power processing algorithms。

Charge and discharge testing equipment

1, Using energy feedback structure, the battery discharge generated electricity to the electricity or directly transferred to the need to charge the battery pack to solve the energy loss and heat dissipation workshop.

2, All systems in the power part of the power simulation and thermal system simulation, design redundancy of over 30%, to ensure that the machine's stability and reliability.

3, with constant current, pulse, ramp charge and discharge, constant current limiting, constant current limiting / limit, variable current charging, constant power, constant resistance and other charge and discharge work.
