Abstract

The invention relates to the technical field of batteries, in particular to a vehicle ternary battery pack low-temperature control module which comprises a battery pack control system connected with a vehicle control system, and the vehicle control system is connected with a communication transmission unit and an instrument display unit. The battery pack management and control system comprises a management and control unit, a thermal management control unit, a signal detection unit and a battery monitoring unit, the management and control unit is connected with the thermal management control unit and the battery monitoring unit, and the battery monitoring unit is further connected with the signal detection unit. The condition of the battery pack is divided through the battery detection unit, it is guaranteed that the battery is charged and discharged under the safe condition, then it is guaranteed that the temperature of the battery pack under the low-temperature condition is raised, and it is guaranteed that the battery pack is in stable and efficient output.

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 ...
