Description

An intelligent control type cover plate for a battery

technical field

The utility model relates to the technical field of vehicle batteries, in particular to an intelligent control type cover plate of a battery.

Background technique

Batteries are an indispensable part of automobiles and can be divided into traditional lead-acid batteries and maintenance-free batteries.

Since the battery uses lead-calcium alloy as the grid, the amount of water decomposition and evaporation of water generated during charging is low. In addition, the shell adopts a sealed structure, and the released sulfuric acid gas is also very small, so it is compared with traditional batteries. , It has the advantages of no need to add any liquid, to the wire pile head, and long power storage time.

For traditional single lead-acid batteries, valve-regulated batteries, motorcycle batteries, or lithium power batteries for new energy vehicles, the positive and negative electrodes are both bare, that is, the positive and negative electrodes are not only exposed outside the battery body, And it is still connected to the interior and is charged. This puts the battery at risk during assembly and transportation. Once a conductor connects the two electrodes, a short circuit will occur, resulting in an electric fire. The newly invented intelligent control battery has positive and negative electrodes on the outside, but the positive electrode does not output voltage and current in the absence of an input signal, which greatly reduces the risk. Security risks are guaranteed to be further controlled.
