Power supply system with buffering function for new energy automobile

Abstract

The invention relates to a power supply system with a buffering function for a new energy automobile. The system includes a power supply device. The power supply device comprises a connecting box, a protective cover and a main body, wherein the connecting box is in a cuboid shape; the main body is arranged in the connecting box; the protective cover covers the top of the connecting box; the protective cover is hermetically connected with the connecting box; heat dissipation holes are formed in the two sides of the connecting box; the main body is provided with a buffer mechanism and a protection mechanism; the buffer mechanism comprises a fixed pipe, a movable disc and at least two first springs; the protection mechanism comprises a protection pipe, at least three pushing assemblies and atleast three locking assemblies. The system achieves the buffering and vibration reduction effects through the buffering mechanism, and achieves a fire extinguishing function through the protection mechanism, and the safety is improved.

Description

technical field [0001] The invention relates to the field of new energy batteries, in particular to a power supply system with a buffer function for new energy vehicles. Background technique [0002] Lithium-ion battery is a kind of new energy battery. Because of its high energy density, high power, small self-discharge, excellent cycle performance, and high charging efficiency, lithium-ion battery has become the mainstream of vehicle power batteries. The main direction of development of major new energy battery factories. [0003] When the existing lithium-ion batteries used in new energy vehicles are in use, due to the bumps in the driving process of the car, the casing cannot provide buffer protection for the batteries, which may easily cause loose connection parts of the lithium-ion batteries and shedding of solder joints, reducing the Not only that, but the existing lithium-ion batteries will spontaneously ignite due to aging and other reasons, causing new energy vehic...
