Battery overvoltage protection function of charge control chip
The battery overvoltage protection (OVP) function of the charge control chip is a key technology to ensure battery safety and extend battery life. Here are five key points to summarize this feature:
Main component
Prevent battery damage
Overvoltage protection function by monitoring the battery charging voltage, when the voltage exceeds the set safety threshold, the OVP mechanism will start, cut off or limit the power supply, to prevent battery damage due to overcharge.
Protection of the rear circuit
Input overvoltage protection can prevent damage to the rear circuit and chip caused by too high input voltage to ensure the safe operation of the charging pile and battery.
Automatically turn off output
Some overvoltage protection chips, such as the JX2212, have an internal default overvoltage threshold (e.g. 6.1V), when the input voltage exceeds this value, the output will be cut off, protecting the device from damage.
Temperature monitoring and protection
Some overvoltage protection chips are integrated with overtemperature protection (OTP) function, which can monitor the chip temperature and automatically turn off the output when the temperature is too high to prevent the equipment from overheating and damage.
Integrated multiple protection functions
Modern charge control chips usually integrate a variety of protection functions, including OVP, overcurrent protection (OCP), short circuit protection, etc., to provide a comprehensive battery protection scheme.
Through these functions, the OVP function of the charge control chip provides comprehensive protection for the battery, ensuring the safety and reliability of the charging process.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
