Description

technical field [0001] The invention relates to the technical field of new energy, in particular to an integrated soft pack fast-charging battery pack. Background technique [0002] With the strengthening of environmental protection awareness and the support of national policies, in the next few years, new energy electric vehicles will cover major roads in urban and rural areas at a rapid growth rate. As an electric vehicle, the biggest safety hazard is the reliability of the power battery. For example, in the high and low temperature weather of 40 degrees Celsius in summer and tens of degrees below zero in winter, can the power battery work safely and reliably? This requires our R&D engineers to do enough homework on the heat dissipation of the power battery. [0003] There are two types of battery pack heat dissipation, active and passive, and there is a big difference in efficiency between the two. The cost required by the passive system is relatively low, and the meas...

Problems solved by technology

Therefore, whether it is a lithium battery or a lithium iron phosphate battery, their working temperature must not be higher than 60°C, but if the outdoor temperature reaches nearly 40°C in summer, and the heat generated by the battery itself is large, the working environment temperature of the battery will rise. , and if thermal runaway occurs, the situation will be very dangerous
