Description

technical field [0001] The invention relates to the field of automotive power batteries, in particular to a battery pack. Background technique [0002] As a new energy vehicle, electric vehicles have been widely promoted at present, and lithium-ion batteries have the advantages of small size, light weight, and no pollution to the environment, so battery packs composed of lithium-ion batteries are widely used in electric vehicle power batteries . For power batteries for electric vehicles, power batteries must meet the four requirements of high specific energy, high specific power, long life, and high safety, as well as the requirements for battery packs, so as to meet the needs of contemporary consumers for power vehicles. [0003] At present, cars usually use battery packs with designed rated voltages to assemble them in the car. However, different types of cars require different output voltages. As a result, the production of battery packs needs to be composed of battery p...

Problems solved by technology

In addition, the current vehicle power battery may be short-circuited due to various factors during use, causing the battery pack to burn out. Since the batteries in the battery pack are connected together, when a short circuit occurs in one place, the excessive current May cause damage to the entire battery pack, making the battery pack poor in safety and economy

Moreover, the number of cycles of the battery is not only related to manufacturing factors, but also inseparable from the environment in which the battery is used.
