Electric vehicle fire accidents are mostly due to lithium battery failure and spontaneous combustion

According to information released by the Fire and Rescue Bureau of the Ministry of Emergency Management in July, electrical faults and spontaneous combustion are the main causes of electric vehicle fires, accounting for 62.1 percent and 23.5 percent of the total number of electric vehicle fires respectively. Overcharging, single Lead acid battery failure and short circuit of electric circuit are the fundamental causes of electric vehicle fire.

National Light Electric Vehicle and Lead Acid Batteries Product Quality Inspection Center analysis of electric bike related safety accidents found that: in the past, there were more traffic accidents, now there are more fire accidents; Vehicle modification is the main cause of accidents; Maintenance Free Battery and chargers are a major source of accidents. China Consumer Association united the center suggested that consumers must buy electric bicycles in legitimate businesses, and before purchase,they`d better carefully check whether its meet a mandatory product certification, understand the battery type, capacity, model and other related components parameters, dont buy any bad or unqualified products including non-standard marks, exceed the standard electric bicycle.

Use the original charger and charge it moderately. The original charger is compatible with the charging protection function of the battery. Otherwise, the battery may be damaged during the charging process, which increases the security risk. Firstly, pay attention to avoid overcharging, as charging a long time will not only affect the battery performance, but also easily cause fire and explosion due to continuous high temperature heating of the battery. Then, dont forget to cut off the power supply in time after the battery is full. Secondly, Its also important to pay attention to standard layout the cable distribution, and authority highly recommended to install short circuit and leakage protection device. Thirdly, we should pay attention to the charging environment. When charging, we should put the charger in a place where it is easy to dissipate heat, and check the charging situation at any time. Try not to choose charging during sleep at night.

Do not illegally modify e-bikes. Some companies or shops increase the battery capacity without authorization, for example: illegally convert large in volume but with small capacity lead-acid batteries into small size but large capacity Lithium Batteries. In this process of modification, it is easy to destroy the safety performance of the vehicle electrical line, which will lead to the failure of the vehicle electrical line overload, short circuit and so on. China Consumer Association reminds consumers not to illegally modify, if the electric bicycle battery is expired or have quality problems need to be replaced, should try to replace the same type of battery products, to avoid accidents caused by the battery is not suitable.

Cusumers should enhance safety awareness and do inspection and maintenance frequently. Consumers should avoid electric bicycles or batteries be exposed to the sun, rain and other conditions, keep from from heat sources as far as possible, In order to not affect the heat dissipation performance of the Lithium Battery, resulting in high internal temperature of the battery. It is recommended to check, maintain the electric bicycle lines, batteries and other parts every year to avoid "overdue service".
