Abstract

The invention belongs to the technical field of automobile batteries, and discloses a split battery pack system. Sub-battery packs are placed inside the battery compartment, and multiple sub-battery packs in different battery compartments are connected to power supply circuits through parallel connections; the inside of the battery compartment is fixed by bolts. There is a temperature sensor; the bottom of the battery compartment is fixed with multiple springs by bolts, the outer side of the battery compartment is connected with a protective cover through a spring hinge, and the other end of the protective cover and the battery compartment are respectively provided with electric control locks that cooperate with each other. The present invention can monitor the temperature data of each small battery pack in real time by putting the small battery packs into a separate battery compartment through a temperature sensor. Immediately start the solenoid valve of the electric control lock to automatically open the battery compartment door, and the battery pack is automatically and quickly ejected 2 meters away from the vehicle under the spring force in the battery compartment, preventing the entire vehicle from being burned and scrapped, with high safety and reduced economic losses .

Description

technical field [0001] The invention belongs to the technical field of automobile batteries, and in particular relates to a split battery pack system. Background technique [0002] At present: New energy vehicles are driven by lithium batteries to drive motors. Because lithium batteries are explosive, there are often reports of spontaneous combustion of electric vehicles when the vehicle is driving or parked. [0003] Existing electric vehicles are mainly composed of multiple groups of batteries to form a battery pack to supply electric energy to the electric vehicle. However, when some batteries spontaneously ignite during the use of traditional electric vehicles, it is impossible to effectively prevent the battery from fire prevention, making the spontaneous combustion The battery will ignite the surrounding batteries, which will cause the electric vehicle to spontaneously ignite, causing personal hazards and property losses. [0004] Through the above analysis, the probl...
