Rechargeable batteries in electric vehicles, electric tools, especially the widely applied lithium ion batteries have to work in a smart energy management system. The battery charge and discharge process is controlled and protected by the intelligent charge and discharge circuit to ensure electricity equipment stable operation under various environmental temperature, including low temperature and high temperature environment.
The following is a schematic diagram of a charging control unit in the battery pack using NTC thermistor as the temperature sensor.
