The lithium battery protection board is a core component of the intelligent management system for lithium-ion batteries. Its main functions include overcharge protection, over-discharge protection, over-temperature protection, over-current protection, etc., to ensure the safe use of the battery and extend its service life.
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.
Prevent the battery from being damaged by excessive current. Important technical parameters of lithium battery protection boards include overcharge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection, internal resistance, power consumption, etc.
To build the battery pack, we are taking 4 cells in series and adding a parallel cell, so we have double the voltage and capacity per cell. See the diagram above for how to go about connecting the cells. The only limiting factor is that all of the cells need to be identical.
The microcontroller will send a control signal when the battery voltage and current exceed or fall below the set threshold. The MOS tube is turned on or off to control the charge and discharge of the battery. Part 3. How does the lithium battery protection board protect the battery? 1. Overcharge protection
Lithium ion or polymer cells need to be protected from under or over discharging, which can be really bad. This is done by a battery management system/board, or BMS. It's a device that combines battery protection for multiple cell batteries like we are building. It’s called a battery management system or BMS for short.
