Problems solved by technology

[0003] With the popularity of electric bicycles, more and more manufacturers begin to pay attention to their own technical advantages. However, due to the limitation of battery technology, the existing electric bicycles have limited battery life. Once a breakthrough is made in the battery life, the consumption of Because the existing battery modules generate a lot of heat when charging, on the one hand, it is not conducive to the safety of charging; The discharge efficiency of the group is reduced. Secondly, the use environment of the existing electric bicycle is relatively complicated, which will generate a large amount of vibration, resulting in poor stability of the electrode connection of the motor module. After a long period of use, it is very likely to cause a sudden power failure during use.
