Abstract

The invention discloses a detection system for a vehicular storage battery. The detection system comprises a CPU (Central Processing Unit) and a signal acquiring and converting module, a display interface, a keyboard interface and an alarming circuit as well as a power supply circuit. The detection system disclosed by the invention can be used for detecting under-layer important information of a storage battery on line in real time, mainly detecting terminal voltage forming single section of battery in the battery pack, discharging current and charging current of the battery pack, the temperature of the battery and other important information and simultaneously acquiring ambient temperature for referencing. The system can be used for directly displaying the information. On the basis, various analysis functions to the acquired information are achieved, wherein the analysis functions mainly comprise unbalanced judgment of the battery, temperature abnormal indication, over charging indication, over discharging indication and deep charging indication. In addition, the indication of residual electric quantity and the judgment on the health condition of the battery can be realized so asto provide effective help for users using the battery to better use and maintain the batteries.

Description

technical field

[0001] The invention belongs to the technical field of battery management, in particular to a vehicle battery detection system. Background technique

[0002] At present, power storage batteries are widely used in railway locomotives, electric vehicles, especially the very popular electric bicycles. Their common feature is that multiple identical batteries are connected in series to supply power to the load in groups. However, most of the current vehicle control systems are too simple to reflect the battery status information. Taking electric bicycles that are widely used at present as an example, the display only reflects the voltage of the entire battery pack to measure the remaining power of the current battery. On the one hand, the total voltage of the battery pack does not have a good linear relationship with the remaining capacity of the battery, and the reliability of the indication of the remaining capacity is not high. In actual use, it is found tha...
