Battery Balancing Machine
High Precision Battery Test Equipment
Product overview:
The battery balancing machine is a high precision battery test equipment used to solve the voltage difference of different cells in the same battery pack. By charging and discharging all battery cells in the same string, the voltage difference of each battery cell tends to zero. This achieves battery cell balance and extends the service life of the battery pack.
Multiple battery balancing machines charge or discharge single battery cells at the same time without disconnecting the cell-to-cell connector. It can balance batteries in series. The cut-off condition can be set to voltage, current or capacity.
Scope of application:
The battery balancing machine is a high precision battery test equipment, suitable for the repair and maintenance of ebike batteries, electric motorcycle batteries, car batteries, EV batteries, ESS batteries, drone batteries, electric forklift batteries and other batteries.
Features:
1. Battery balancing machines in different cabinets are isolated from each other, allowing simultaneous charge and discharge of multiple cells in the same battery pack for battery cell balancing to repair and maintenance the battery pack.
2. Each battery balancing machine is independently controlled and different test processes can be performed simultaneously.
3. This high precision battery test equipment uses four-wire measurement sampling to ensure high measurement accuracy.
4. This high precision battery test equipment adopts a modular design and is easy to debug and maintain.
5. Battery balancing machines from multiple cabinets can be used in parallel via a middle machine connection, which increases the current range.
6. The high precision battery test equipment has battery anti-reverse polarity protection.
7. Each interface of the battery balancing machine software is clearly displayed and the operation is simple and easy to use.
8. The battery balancing machine has powerful software protection functions, such as over-voltage protection, under-voltage protection, over- current protection, over-charge capacity protection, and over-discharge capacity protection, etc.
