A battery parameter monitor

Abstract

The invention relates to a storage battery parameter monitor which comprises a liquid crystal display module, a main processor circuit, a second communication interface circuit, a first communication interface circuit, a bottom-layer processor circuit, voltage monitoring circuits, a current monitoring circuit and a battery pack. The battery pack comprises multiple batteries. The number of the voltage monitoring circuits is identical to that of the batteries. A positive electrode and a negative electrode of each battery are in bridge joint with one voltage monitoring circuit. The current monitoring circuit is connected with the battery pack in series. The output end of each voltage monitoring circuit and the output end of the current monitoring circuit are respectively connected with the corresponding input ends of the bottom-layer processor circuit. The corresponding output end of the bottom-layer processor circuit is further connected with the first communication interface circuit. The second communication interface circuit and the liquid crystal display module are respectively connected with the main processor circuit. According to the storage battery parameter monitor, the risk of performance reduction of the whole battery pack is reduced, the service life of the whole battery pack is prolonged, the system maintenance cost is reduced, and the reliability of a whole vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of storage battery state monitoring, in particular to a storage battery parameter monitor for small electric vehicles. Background technique [0002] At present, lead-acid battery packs are widely used for power supply in small electric vehicles. In actual work, due to manufacturing, aging and other factors, in a group of battery packs, individual batteries often have insufficient or low voltage. As a result, the total battery voltage drops, thereby increasing the current of the battery pack, and long-term use will lead to a decrease in the life of the entire battery pack. At present, in small electric vehicles, no measures are taken to detect the voltage of each battery in the battery pack, which often leads to a reduction in the life of the entire battery pack and increases the maintenance cost of the entire vehicle. Contents of the invention [0003] In order to solve the above-mentioned technical probl...

Problems solved by technology

[0002] At present, lead-acid battery packs are widely used for power supply in small electric vehicles. In actual work, often due to manufacturing, aging and other factors, in a set of battery packs, individual batteries often have insufficient or low voltage. As a result, the total battery voltage will drop, and the current of the battery pack will increase. Long-term use will lead to a decrease in the life of the entire battery pack.

At present, in small electric vehicles, no measures are taken to detect the voltage of each battery in the battery pack, which often leads to a reduction in the life of the entire battery pack and increases the maintenance cost of the entire vehicle.
