Electric bicycles are convenient and environmentally friendly means of transportation. However, electric bicycles still have potential safety hazards. According to statistics from relevant departments, more than 90% of electric bicycles explode due to changes in battery performance caused by high temperature, causing fires and seriously affecting the safety of people's lives and property.
The battery is the core element of an electric bike. People are in the driver's seat when driving an electric bicycle, and it is difficult to detect problems such as battery heating in time. In the process of driving or charging an electric bicycle, the battery failure or the collision of the vehicle body will cause heating and heat generation, and the battery is sealed in the narrow interior space of the electric vehicle, which is not conducive to heat dissipation, and it is easy to cause a fire. Therefore, a battery temperature monitoring system is required to monitor the temperature.
The dynamic temperature monitoring system of electric bicycle lithium battery temperature is composed of FPGA chip, data memory, battery protection switch, four NTC temperature sensors set in the electric bicycle lithium battery battery pack, ambient temperature sensor placed on the surface of the battery box, and placed in the battery box. Surface temperature monitoring system alarm composition.

The NTC temperature sensor in the lithium battery pack of the electric bicycle mainly monitors the real-time temperature change of the battery under different ambient temperatures in real time, and provides a power outage alarm for the abnormal conditions collected. It avoids the potential safety hazard caused by abnormal temperature during electric bicycle driving and charging process caused by the defect of battery temperature monitoring, and improves safety.
