The protection board automatically cuts off the charging circuit when the battery is charged to the set voltage. Prevent battery overcharging. 2. Over-discharge protection The protection board automatically cuts off the discharge circuit when the battery discharges to the set voltage. Prevent the battery from over-discharging. 3.
Protection boards for lithium batteries offer monitoring protection. Low-voltage lithium batteries require a protection board. When using high-voltage lithium batteries, a battery management system (BMS) is typically chosen since these systems contain more functions for monitoring the state of the battery pack.
You can also obtain custom-built protection boards with your custom battery packs. This arrangement is ideal since the battery manufacturer will have a greater understanding of the protection needs of the custom pack that they design for the customer. So, the protection board would cater to these design requirements.
In addition to basic overcharge, over-discharge, over-current, and over-temperature protection, future lithium battery protection boards will also integrate more functions, such as power estimation, balanced charging, etc. These features will help improve the efficiency and management of lithium batteries. 3. Intelligent
As the temperature rises, the resistance of the NTC will increase. When the resistance drops to the set value, the CPU will issue a shutdown command to stop charging the battery, thereby protecting the battery. A BMS has the protection of overcharge, discharge, short circuit, and temperature protection.
When it rises to the protection voltage of the battery cell (overcharge protection voltage), at this time COUT will output a high level to turn off the corresponding MOS switch, and the charging circuit will also be turned off. , after overcharge protection, the cell voltage will drop.
