[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.

The invention relates to a storage battery state display device which comprises a liquid crystal display module, a main processor circuit, a second communication port circuit, a first communication port circuit, a bottom-layer processor circuit, voltage monitoring circuits, a current monitoring circuit and a battery pack. The battery pack comprises a plurality of batteries, the number of the voltage monitoring circuit is the same as that of the batteries, the positive pole and the negative pole of each battery are connected with one voltage monitoring circuit in a crossing mode, the current monitoring circuit is in series connection with the battery pack, the output ends of the voltage monitoring circuits and the output end of the current monitoring circuit are connected with the corresponding input ends of the bottom-layer processor circuit respectively, the corresponding output end of the bottom-layer processor circuit is further connected with the first communication port circuit, and the second communication port circuit and the liquid crystal display module are both connected with the main processor circuit. The storage battery state display device reduces the risk that the performance of the whole battery pack is reduced, prolongs the service life of the whole battery pack, reduces maintenance cost of the system and improves reliability of a whole vehicle.
Description
technical field [0001] The invention belongs to the technical field of storage battery state monitoring, and in particular relates to a storage battery state display device. 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 problems, the obje...
