Abstract

The invention discloses a device for monitoring batteries of an electric vehicle and a method for monitoring the batteries. The monitoring device comprises a battery management system BMS, a temperature sensor, and a processor, wherein the battery management system BMS is arranged in the battery box of the electric vehicle and comprises a temperature probe which is used for collecting the internal temperature of the battery box; the temperature sensor is arranged outside the battery box of the electric vehicle and used for acquiring the external temperature of the battery box; the processor is respectively connected with the BMS and the temperature sensor and used for determining the actual temperature of the battery pack in the battery box according to the internal temperature and the external temperature. Through the device and the method, the problem that the monitoring reliability of the batteries is relatively low in an existing technology is solved, thus the monitoring reliability of the batteries is improved.

Description

technical field [0001] The invention relates to the battery field, in particular to a monitoring device and method for an electric vehicle battery. Background technique [0002] With the promotion of electric vehicles, how to improve the safety of the battery itself and how to improve the safety of battery use have become a new direction of battery research. However, the inventor found that the current monitoring of the battery temperature is based on the results of the battery pack temperature collected by the battery management system (Battery Management System, referred to as BMS) inside the battery box. However, due to the closed environment inside the car, The temperature outside the battery box will have an adverse effect on the battery box to a large extent, endangering the safety of the battery and the car. [0003] Aiming at the problem of low reliability in the monitoring of electric vehicle batteries in the related art, no effective solution has been proposed so ...
