Problems and solutions in actual use of lithium-ion batteries for E-bicycles

　　The use scenarios of electric two-wheeled vehicles have high technical requirements for lithium-ion batteries.

　　E-bicycle often encounters collisions and falls, while riding in the rain and wading are very common.

　　The charging environment of electric two-wheeled vehicles is relatively harsh. Random use of chargers that do not match the lithium-ion battery can cause overcharging, damage the battery, and even cause safety accidents.

　　These actual use scenarios will cause damage to the performance of the lithium-ion battery.

　　Based on the above actual scenarios, how can lithium batteries be designed to better meet the real needs of consumers?

　　1. The waterproof level of lithium batteries must be high enough to meet the needs of consumers.

　　2. The Li-ion battery of the E-bicycle is recommended to use a high-strength PC+ABS battery plastic case that is drop-proof and shock-proof, which can effectively protect the internal and external structure of the battery;

　　3. V-0 grade flame-retardant casing to prevent safety problems caused by high temperature outside the battery;

　　4. A dedicated charger equipped with a smart handshake protocol can effectively prevent potential safety hazards caused by the abuse of the charger.

　　5. The Internet of Everything has become a major trend in future life, and E-bicycles are no exception. To achieve the effect of interconnection and intelligence, only lithium batteries can do it, and traditional lead-acid batteries do not have this ability.

　　With the help of the BMS system, the Li-ion battery can realize the intelligent management of the whole vehicle to the Li-ion battery and realize the interaction between people and vehicles. The advanced BMS system, by adding multiple sets of sensors, will record battery drops, collisions, etc., and send them to the data backend. The background will analyze the battery condition and deal with the problem, and send the battery usage status to the user through the APP, so that the user can understand the status of the Li-ion battery in the first time.

　　The BMS system also realizes accurate battery display of the entire vehicle, which highly improves the user's riding experience.

　　The development of electric bicycle batteries must be from lead-acid batteries to lithium-ion batteries, especially lithium iron phosphate batteries, and from no data use to intelligent applications.
