Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] Aiming at the problems existing in the prior art, the present invention provides a split battery pack system, which will be described in detail below with reference to the accompanying drawings.

[0033] Such as figure 1 As shown, the battery compartment 1 in the split battery pack system provided by the embodiment of the present invention is provided with a plurality of battery compartments arranged in sequence. The multiple sub-battery packs 2 in 1 are connected to the power supply circuit through parallel connection; the temperature sensor 3 is fixed by bolts in the battery compartment 1, and the temperature sens...

Abstract

The invention belongs to the technical field of automobile batteries, and discloses a split type battery pack system. Sub-battery packs are placed in battery cabins; the sub-battery packs in the different battery cabins are connected with a power supply circuit through parallel connection; a temperature sensor is fixed in each battery cabin through a bolt; a plurality of springs are fixed to the bottom of each battery cabin through bolts; a protective cover is connected to the outer side of each battery cabin through a spring hinge shaft, and electric control locks matched with each other arearranged at the other end of the protective cover and the battery cabin respectively. According to the split type battery pack system of the invention, the small battery packs are put into the singlebattery cabins, so that the temperature data of each small battery pack can be monitored in real time through the temperature sensors; when it is monitored that the temperature of the sub-battery packin one battery cabin rises rapidly, a vehicle-mounted control system immediately starts the electromagnetic valves of the electric control locks to automatically open a battery cabin door, the battery pack is automatically and rapidly ejected out of a vehicle by 2 m under the elastic force of the springs in the battery cabin, the whole vehicle is prevented from being burnt and scrapped, safety ishigh, and economic losses are reduced.

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...
