The safety problems of lithium-ion batteries mainly include overcharge, over-discharge, high temperature, short circuit, etc. These problems may lead to battery fire, explosion and other serious consequences. To improve the safety of lithium-ion batteries, several technologies can be used:

Anti-overcharging technology: Prevent battery overcharging by improving the battery management system. When the battery power is too high, the management system will automatically cut off the charging current to avoid safety issues caused by overcharging of the battery.

Anti-over-discharge technology: By improving battery materials and structures, the over-discharge protection performance of the battery is improved. An over-discharge protection device can be added inside the battery to automatically cut off the discharge current when the battery voltage is too low to avoid performance degradation and safety issues caused by over-discharge of the battery.

Temperature control technology: Strengthen battery temperature monitoring and management by improving the battery cooling system. When the battery temperature is too high, the management system will automatically adjust the heat dissipation system to control the battery temperature within a safe range to avoid safety issues such as fire or explosion caused by high temperature.

Anti-short circuit technology: By improving the battery structure and design, the battery's anti-short circuit performance is improved. An anti-short circuit device can be added inside the battery to automatically cut off the current when a short circuit occurs in the battery to avoid safety issues such as fire or explosion caused by excessive current.

Intelligent monitoring technology: By improving the battery management system, intelligent monitoring and management are achieved. The management system can monitor battery voltage, current, temperature and other parameters in real time, detect and handle abnormal situations in a timely manner, and avoid safety issues.
