Abstract

The invention provides a battery low-temperature automatic preheating device and system. The battery low-temperature automatic preheating device comprises a battery pack module (103), a switch controlmodule (102) and an external heater module (101), wherein the battery pack module (103) and the external heater module (101) are connected in series through the switch control module (102); the switch control module (102) can realize the on / off state of a circuit where the three modules are connected under the effect of a set switch signal (23); and the battery pack module (103) is disposed within the thermal radiation range of the external heater module (101). The battery low-temperature automatic preheating device, by using an intermittent variable-frequency pulse group discharge preheatingmode and the energy of the battery itself, and by controlling the frequency and the duty ratio of the pulse discharge through intelligent identification, reasonably discharges and rapidly heats the battery at different temperatures, and ensures sufficient electrochemical reaction recovery time.

Description

technical field [0001] The present invention relates to the technical field of power supply emergency starting, in particular to a low-temperature automatic battery preheating device and system, and in particular to a low-temperature automatic low-temperature automatic preheating system for a lithium battery of a multi-functional vehicle emergency start power supply activated by intermittent frequency conversion pulse groups. Background technique [0002] As car life becomes more and more abundant, people's dependence on cars is getting deeper and deeper. Therefore, along with the application of the emergency starting power supply of automobiles, it is becoming more and more extensive. The multi-functional emergency starting power supply is one of the essential vehicle tools in the life of car enthusiasts. In recent years, with the rapid rise of lithium battery technology, the original power-only lead-acid battery emergency starting power supply was quickly replaced by lithi...
