Since the beginning of 2019, Electric Bicycle spontaneous combustion and explosion accidents have occurred in multiple places, causing multiple casualties. The cause of the accident is mostly due to the malfunction of the Lithium Battery of Electric Bicycles during the charging process, which has attracted much attention to the safety issues of Electric Bicycles.
At present, the consumer demand for Electric Bicycles is showing an increasing trend. According to the information released by the China Bicycle Industry Conference, the social ownership of Electric Bicycles reached nearly 300 million in 2019. It is expected that the epidemic will lead to the rise of the "cloud economy", which will increase the demand for Electric Bicycles in some industries such as delivery and logistics.At the same time, with the saturation of the automotive power battery market, some less competitive Lithium Battery companies are accelerating their entry into the Electric Bicycle market, invisibly increasing the safety hazards of Electric Bicycles.
Lithium Batteries generally have the problem of violent impact or ignition under high temperature conditions, so the heat dissipation and collision safety protection of Lithium Batteries themselves are very important. However, due to the product and usage characteristics of Electric Bicycles, their battery size is smaller and often directly exposed to the external environment, which increases the risk of accidents in Electric Bicycles.Therefore, during the process of battery delivery, it is very important to detect thermal control and external unstable factors, but this also increases the production costs of Electric Bicycle manufacturers.
