Overcharge Protection and Recovery When the voltage of any cell is higher than the setting value of the single cell overcharge voltage, and the duration reaches the single cell overcharge delay, the system enters the overcharge protection state, turns off the charging MOS, and battery will cannot be charged. After the single cell overcharge protection, when the […]
What is lifepo4 battery? Lithium ion batteries are the most common type of rechargeable battery in the world. They are widely used in electric vehicles, smartphones, and laptops. Recently, a new type of battery has been introduced-the LIfePO4 battery. This is different from the typical lithium ion battery because it can be discharged and recharged […]

The protection function of lithium battery is usually completed by the cooperation of the protection circuit board and PTC or TCO and other current devices. The protection board is composed of electronic circuits. It can accurately monitor the voltage of the cell and the current of the charging and discharging circuit at the time of -40℃ to +85℃, and control the on-off of the current circuit immediately. PTC or TCO protects the battery from severe damage at high temperatures.
The circuit and parameters of lithium battery protection board vary according to the IC and voltage used. The commonly used protection ICs include 8261, dw01 +, CS213, gem5018, etc. among them, the precision of Seiko 8261 series is better, and of course, the price is more expensive.
