An electric vehicle safety management system and method

Abstract

The invention provides an electric vehicle safety management system and method. The electric vehicle safety management system comprises an electric vehicle and a service station system. The electric vehicle comprises a battery pack installation position, and the battery pack installation position is detachably mounted with a battery pack to be tested. The service station system includes a mountingand dismounting device and a safety detecting device, and the mounting and dismounting device is configured to replace the battery pack to be detected on the battery pack installation position into asafe battery pack which has been fully charged and has passed a safety test after the electric vehicle is detected to be within a preset distance range. The safety detecting device is configured to perform safety detection on the battery pack to be tested that has been replaced by the mounting and dismounting device according to preset safety inspection items. In the embodiment of the present invention, after the battery pack to be detected of the electric vehicle was replaced by the service station system, the battery pack to be detected after the replacement is subjected to safety detectionand identification to eliminate problematic battery packs, thereby improving the safety of the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle safety, in particular to an electric vehicle safety management system and method. Background technique [0002] At present, with the continuous popularization of electric vehicles, phenomena such as ignition and burning of electric vehicles also occur more and more frequently. At this stage, the battery packs of electric vehicles are mainly made of chemical materials, and their chemical properties are relatively active. At the same time, because the working principle of the battery pack is chemical reaction, the process is difficult to control. collapse etc. In addition, the bumps of electric vehicles are also prone to micro-short circuits in the structure of battery modules and battery packs. These phenomena are generally mild in the early stage, and it is difficult to identify them through the protection system of electric vehicles. However, if left unattended, it is easy to cause The...

AI Technical Summary

Problems solved by technology

For example, there is a dead zone in the temperature detection of the existing battery pack PACK. Generally, there are only two temperature sensors for the 12 cells in the VDA battery module. ) It is difficult to effectively monitor the temperature of the battery pack PACK

As another example, the existing BMS-based strategy for evaluating the battery health status is not accurate enough to accurately detect the health status of the battery pack.

For another example, in the prior art, when the electric vehicle is parked, the battery management system does not work, and at this time the battery pack cannot be effectively monitored for safety
