　　button battery cr2032 electric vehicle, technical analysis of button battery cr2032 pack. The technical level of my country's power batteries has reached the international leading level. In recent years, my country's lithium battery electric vehicle industry has developed rapidly. New energy vehicles with button battery cr2032 packs are the mainstream of the market and have advantages such as cost and energy density. However, subsequent battery loss and battery life Problems such as shortened time and low value retention rate are also problems that consumers cannot ignore during later use.

　　button battery cr2032 electric vehicle

　　Friends who buy electric vehicles have all heard of the name of button battery cr2032 packs. Common BAIC New Energy, BYD, Tesla, etc. all use this kind of battery. In recent years, the new energy vehicle industry has developed rapidly. Among them, button battery cr2032 electric vehicles with high driving range have developed even more rapidly and become the main force in the market.

　　1.Tesla MODEL

　　Tesla is the first company to try to use huge quantities of button battery cr2032 packs in electric vehicles, which is worthy of admiration. However, what is even more worthy of praise is Tesla's superb marketing methods, which made the originally stable market. A Tesla whirlwind blew up in the electric car market, attracting more people's attention.

　　There is no doubt that Tesla is the best in the application practice of ternary lithium batteries in electric vehicles. The 18650 battery used by Tesla refers to a lithium battery whose cathode material uses lithium nickel cobalt manganese button battery cr2032 cathode material. Among them, the voltage of lithium-ion battery is usually 3.6V, the voltage of lithium iron phosphate battery is usually 3.2V, and the common capacity is 1500mAh-3100mAh.

　　2. BAIC Senova EV

　　The third version of Senova EV, which is the final mass-produced version (the first 50 units have become APEC designated vehicles), has been replaced with ternary lithium batteries, and its cruising range has been increased to 220-240 kilometers. The batteries replaced are ternary lithium batteries provided by Beijing Electronic Control Aisikai Technology Co., Ltd. (hereinafter referred to as BESK), a joint venture between BAIC and South Korea's SK.

　　3. BMW I3

　　Although BMW has not announced which material is used in its batteries, according to Samsung SDI’s technical path, NCM (ternary lithium material) is its current main technical path. It can be inferred that the BMW i3 should use all It is the same button battery cr2032 pack as Tesla.

　　Technical analysis of button battery cr2032 pack

　　With the new energy vehicle industry's demand for improved cruising range and battery energy density, power batteries have gradually transformed from lithium iron phosphate to the technical route of button battery cr2032 packs.

　　The biggest advantage of the button battery cr2032 pack is the high energy storage density of the battery. Its energy storage density is usually above 200WH/kg. Compared with 90-120WH/kg of lithium iron phosphate, it is more suitable for the passenger car market's demand for cruising range.

　　However, the decomposition temperature of button battery cr2032 materials is around 200°C. It will release oxygen molecules. The electrolyte will burn rapidly under high temperature, causing the risk of spontaneous combustion and explosion of the battery. Therefore, it has high requirements for battery management.
