What are the Functions of BMS?

It can monitor parameters of the battery such as voltage, current and temperature in real - time, prevent the battery from overcharging, overdischarging, overcurrent, short - circuit and overheating to ensure safety. It can also balance the power of each cell within the battery pack, improve the overall performance and lifespan, and accurately estimate the remaining battery power, providing a basis for the rational use of the battery.

How to Match the BMS with Battery?

Consider these when matching a BMS with a battery:

1. Voltage compatibility: Know battery cell setup and system voltage. Ensure the BMS fits and sets protection thresholds right.

2. Current matching: Pick a BMS with enough rated current (for both continuous and pulse) and a safety margin.

3. Chemical compatibility: Choose or configure a BMS specific to the battery type and its parameters.

4. Function fit: Basic protections must meet safety needs. Add extra functions as required.

5. Physical fit: Select a BMS sized and installed to match the battery pack.

6. Communication & management fit: Go for a BMS with a proper comms interface that works with your system.
