Description

technical field

[0001] The invention relates to the technical field of batteries, in particular to a low temperature control module for a ternary battery pack for vehicles. Background technique

[0002] The ternary battery pack is composed of a ternary polymer lithium battery. The ternary polymer lithium battery refers to a lithium battery that uses nickel cobalt lithium manganate as the positive electrode material and graphite as the negative electrode material. Compared with lithium iron phosphate batteries, ternary polymer lithium batteries have advantages in high rate charging and low temperature resistance.

[0003] With the intensification of resource consumption and environmental pollution and the research and development of electric vehicles, the discharge temperature of ternary polymer lithium batteries at home and abroad can be as low as -20 °C, and the discharge capacity is greater than 50%, but the performance of the battery is limited. Attenuation can not meet ...
