Chapter 2 Battery Electric Vehicles (BEV) of pure Electric Vehicles (Battery Electric car) L pure electric vehicle - lithium ion battery pure electric vehicle - lithium ion battery Working schematic of lithium ion battery When the discharge is in the opposite direction, lithium is removed from the carbon material and goes back to the anode, which is extremely high in the lithium. Hernia of rechargeable lithium ion from the oxide anode crystal lattice, after passing the organic electrolyte for lithium ion conduction transfer embedded in carbon negative material anode, cathode on rich lithium, lithium anode in a poor state, electronic compensation of electricity at the same time Charge from the external circuit for give to carbon negative, to ensure that the negative electric charge balance; Load balance; Lithium ion battery performance Compared with the traditional chemical power system, it has the following advantages: 1. The ratio energy of li-ion battery can reach 200Wh/Kg and 300Wh/L, which is about the traditional zinc manganese, lead acid 200Wh/Kg and 300Wh/L, which is about 6 times as much as 6 and nickel-cadmium battery of traditional zinc manganese, lead acid and nickel cadmium battery. 2. Wide working temperature range. Can be in - 200 C - + 750 C ring, working temperature range width. Can work at the temperature of the environment; Work in temperature; 3. Good storage performance. A lithium battery usually can be stored at 53 and storage performance is good. Lithium usually 5 to 10 years in storage batteries, lithium secondary battery self-discharge are generally less than 15% (一10 years, lithium secondary battery self-discharge generally less than 15% (one year), about 1/10 of the conventional lead acid, nic
