Low temperature car starting power supply

Abstract

The invention provides a low-temperature automobile starting power supply, which includes a module shell, multiple sets of module batteries, module poles, a plurality of thermistor plates and a heating controller; the multilayer module batteries are arranged on the module Inside the shell; the pole of the module is set on the shell of the module and connected to the battery cell of the module to provide electric energy; multiple thermistor plates are set at the bottom of the battery cell of each layer to control the battery cell of the module Perform heating operation; the heating controller is set in the module shell and connected with the thermistor board, and is used to control the thermistor board to perform heating operation on the module cell. In the present invention, through the setting of the thermistor plate and the heating controller, the automobile starting power supply can still be heated by small current discharge at low temperature, thereby realizing the large current discharge of the subsequent automobile starting power supply; effectively solving the problem of the existing automobile starting power supply The technical problem that the power supply is basically unable to discharge in a low temperature environment.

Description

technical field [0001] The invention relates to the field of battery modules, in particular to a low-temperature automobile starting power supply. Background technique [0002] Existing car starting batteries generally use 12V lead-acid batteries. With the adoption of self-start-stop technology, energy saving and emission reduction requirements, and environmental protection requirements, the voltage of the new generation of car starting batteries is gradually developing in two directions of 24V and 48V. Therefore, the working voltage range of the car starting power supply is 12V-48V. [0003] The existing car starting power supply, whether it is a lithium battery or a lead-acid battery, cannot discharge at a high rate at a low temperature of -20°C, and basically cannot discharge at a temperature of -30°C or even -40°C. [0004] Therefore, it is necessary to provide a low-temperature automobile starting power supply to solve the problems existing in the prior art. Contents...
