Battery pack monitoring system

Abstract

The invention provides a battery pack monitoring system which mainly includes a server, multiple monitoring terminals, multiple sensor units, and a mobile phone APP. Each battery pack corresponds to one monitoring terminal and one external sensor unit. Each sensor unit includes a current sensor for collecting the current on the bus of the corresponding battery pack, a voltage sensor for collectingthe voltage on the bus of the corresponding battery pack, a temperature sensor for collecting the charging temperature on the surface of the corresponding battery pack, and an electrolyte level sensing unit for collecting the electrolyte level of the corresponding battery pack. Each monitoring terminal is used for collecting the signal of the corresponding external sensor unit and sending the current, voltage, charging temperature and electrolyte level of the corresponding battery pack to the server. The battery pack monitoring system can monitor each battery pack in a vehicle team. Thus, each battery pack can be effectively monitored, maintenance and management of battery packs are facilitated, the service life of battery packs is prolonged, the use safety of battery packs is improved, the use cost is reduced, and greater economic benefit is achieved.

Description

technical field [0001] The present invention relates to the field of batteries, and more specifically, to a battery monitoring system. Background technique [0002] At present, forklifts are often used in industrial handling, especially when loading and unloading, stacking and short-distance transportation of palletized goods. Forklifts use multiple battery packs for common power supply, and each battery pack is formed by connecting multiple single batteries. The reliability and stability of the battery pack and the tightness of the management of the battery pack are the guarantees for the normal operation of the forklift. As an important energy storage device and emergency uninterruptible power supply, the battery pack has the advantages of good reversibility, stable voltage characteristics, long service life, wide application range, and abundant raw materials, and has been widely used in various industries. [0003] However, the chemical energy storage method of the sing...

Problems solved by technology

[0003] However, the chemical energy storage method of the single batteries in the battery pack is affected by various factors such as the environment and external power supply conditions, and some single batteries in the battery pack are in the standby state for a long time, so the performance changes of these single batteries are not easy to be detected. If it is discovered in time, it is likely to cause the battery pack to fail, unable to supply power to the forklift normally, and the forklift cannot work normally

[0004] The multiple battery packs in the forklift are used in an open manner. Users cannot monitor the cumulative charge and discharge times of each battery pack, nor can they monitor the current remaining power of each battery pack, charging temperature, and single battery cells in each battery pack. important data such as the electrolyte level, it is impossible to find out whether each battery pack fails in time

Due to the inability to effectively monitor each battery pack, the service life of each battery pack will be reduced. What is more serious is that due to the lack of effective monitoring and maintenance means, the status of each battery pack cannot be grasped in a timely and accurate manner, and the Hidden dangers when each battery pack fails
