Lithium Ion Battery Discharge Tester | Battery Charging Testing System | Battery Cycle Life Test Equipment
Our P-BCDS100V100A is a comprehensive battery test platform that combines high‑precision charging, discharging, and cycle life evaluation in a single integrated system. Designed for lithium‑ion battery manufacturers, R&D labs, and quality assurance centers, it delivers reliable performance across a wide range of cell, module, and pack testing applications.
Lithium Ion Battery Discharge Tester Key Features
Lithium Ion Battery Discharge Tester
Equipped with a bidirectional energy feedback design, the system discharges batteries at up to 100A with ±0.1% F.S. accuracy. Discharge energy is efficiently fed back to the grid (bus feedback efficiency ≥93%), significantly reducing energy costs and heat dissipation requirements.Battery Charging Testing System
The charging module supports constant current (CC) and constant voltage (CV) modes with seamless switching, eliminating voltage or current shocks that can damage cells. With a voltage range of 10–100V and charging current up to 100A, it accommodates multi‑cell series configurations (3 or more cells) and ensures stable, repeatable results.Battery Cycle Life Test Equipment
Perform up to 10,000 cycles with programmable charge/discharge profiles. The system records capacity fade, coulombic efficiency, and voltage curves over time. Data logging intervals are adjustable down to 1 second, and test data can be exported as EXCEL or chart files for in‑depth cycle life analysis.
I. Battery charging testing system Principle and Composition of Equipment
1.1 Host Computer: The host computer software is the main human-machine interaction tool,and functions such as the start, stop, pause, and continuation of the device can be realized through the host computer; the data of battery aging is mainly collected and processed by the host computer, and the test results required by the customer are output.
1.2 Intermediate Computer: The intermediate computer is the central control management software of the device, and the parameters such as capacity and electricity of the battery test are calculated by the intermediate computer.
1.3 Bi-directional ACDC + LLC Isolated DCDC: During charging, this functional module takes electricity from the grid, adjusts it through the bi-directional DCDC, and then charges the battery; during discharging, the functional module returns the energy transmitted by the bi-directional DCDC to the grid.
1.4 Bi-directional DCDC (Buck/Boost): This functional module is a non-isolated DCDC, and it executes the output of the required current and voltage values for battery charging and discharging, i.e., constant current charging, constant voltage charging, and constant current discharging are all executed by this module.
II.Battery charging testing system Scope of Application
Applied to the cyclic charging and discharging, battery function testing, and integrated charge-discharge data monitoring of lithium battery packs for electric tools, solar energy storage, electric scooters, skateboards, electric bicycles, electric motorcycles, and home energy storage systems.
