Deenergized-breakdown-preventing assembled battery for automobile

Abstract

The invention relates to a deenergized-breakdown-preventing assembled battery for an automobile. The technical scheme of the invention is as follows: a lithium battery (7) of the assembled battery for the automobile is mounted in a lithium battery fixing groove (20), a heat insulating plate (6) is arranged at the bottom of a storage battery fixing groove (19), a storage battery (4) is mounted on the heat insulating plate (6), and the upper surface of the storage battery (4) is tightly attached to the lower flat face of a rectangular boss of an upper cover (8). A charging protection circuit module (2) in a battery control circuit is placed in an L-shaped bracket (13), and a power supply switching switch (3) in the battery control circuit is mounted in a switch mounting hole (9). According to the deenergized-breakdown-preventing assembled battery for the automobile, when the storage battery cannot be started up due to deenergization, the assembled battery not only can guarantee the normal start-up of the automobile, but also has the characteristics of simple structure, constantly-sufficient electrical quantity, convenience in operation, high integration level and no need of carrying wiring tools.

Description

technical field [0001] The invention belongs to the technical field of automobile batteries. In particular, it relates to an automobile combined battery for preventing power failure and breakdown. Background technique [0002] In the actual use of the car, when the power is lost due to improper use or loss of the car battery, the car will often break down and cannot be started. This requires an emergency power supply, or the power of other cars to start the car. In some special circumstances , especially in some remote road sections, it is difficult to meet other cars, and it is troublesome and time-consuming to call a car repair shop, and there may not be a car repair shop on the road. Many technicians noticed this problem and proposed their own solutions. [0003] "An emergency starting power supply for automobiles" (CN201520305513) is one of the above-mentioned solutions, and it is also a very representative solution on the market.
