The reasons why it is not recommended to use lithium batteries for electric tricycles include poor safety, high temperature flammability, large battery capacity, poor dissipation thermal and poor charging efficiency.
1. Bad security. Lithium battery packs have high specific energy and are an important development direction for lithium battery packs in the future. However, due to their late start, they cannot better guarantee safety when using the vehicle.
2. It is flammable at high temperatures. Lithium batteries begin to decompose at around 200°C. Under the action of high temperature, oxygen molecules are released and the combustion of the electrolyte is activated. The requirements for the charging environment are therefore more stringent.
3. The capacity of theThe battery is large and the heat dissipation is poor. The large capacity of bus batteries increases the risks associated with lithium batteries. When charging for a long time at high temperatures, the heat dissipation performance of the battery will be poor, resulting in the risk of fire or explosion.
4. Poor charging efficiency. Lithium batteries are much worse than lead acid batteries in terms of charging and discharging. This is a major symptom of the inability to effectively use lithium batteries in today's high-powered vehicles, leading to a decrease in their durability.
Precautions for charging electric tricycles
You must use the on-board configuration and designated special charger to charge, otherwise the battery will be damaged or even cause a fire and other hazards. Disconnect the battery first: when charging, you must firstrd disconnect the battery power switch. The electric vehicle should be placed in a well-ventilated, dry, waterproof and waterproof place. Do not cover the charger and battery with anything to avoid the risk of overheating.
Do not place it near flammable or explosive objects to avoid fire, and the loading place should be kept out of reach of children. Due to the phenomenon of battery self-discharge during storage and transportation, the capacity may be insufficient after first use. However, it can reach its normal capacity after two uses after charging.
