What are the differences between vehicle-mounted UPS batteries and electric vehicle batteries?

What is a vehicle-mounted UPS battery? The vehicle-mounted UPS battery is mainly used as an energy storage power source. When the mains power is interrupted, it supplies 220V alternating current to the load through the method of inverter switching. The energy storage batteries used in current vehicle-mounted UPSs are usually lithium iron phosphate batteries. What is an electric vehicle battery? Electric vehicle batteries are the source of power for electric vehicles. Because of policy subsidies and energy density requirements, most of the current electric vehicles are equipped with ternary batteries. The advantages and disadvantages of different lithium iron phosphate batteries for vehicle-mounted UPS batteries and electric vehicle batteries. The PO bonds in the lithium iron phosphate crystals are stable and difficult to decompose. Forms a strong oxidizing substance, so it has good safety. A report pointed out that in actual operation, a small part of samples were found to burn in acupuncture or short-circuit experiments, but no explosion occurred. In the overcharge experiment, high voltage charging that was several times higher than the self-discharge voltage was used, and it was found Explosion phenomenon. Nevertheless, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries. The advantages and disadvantages of the ternary lithium battery The biggest feature of the ternary lithium battery is that the unit electric energy is relatively large, which is mainly the result of comparison with the lithium iron phosphate battery. It is relatively balanced in terms of capacity and safety, and is a battery with excellent overall performance. High energy density is the biggest advantage of ternary lithium batteries, and the voltage platform is an important indicator of battery energy density, which determines the basic efficiency and cost of the battery. The higher the voltage platform, the greater the specific capacity. Therefore, a ternary lithium battery with the same size, weight, and even the same ampere-hour battery has a longer battery life with a higher voltage platform.
