Abstract

The invention provides a battery system for a vehicle and the vehicle. The battery system comprises a shell, a battery module, a detection device and a control device. The shell is provided with an inner cavity. The battery module is arranged in the inner cavity. The detection device comprises a body and a detection circuit arranged on the body. The detection circuit is provided with a signal output end and is configured to be broken by gas damage generated in the battery module when thermal runaway occurs in the battery module, and the signal output end outputs a circuit disconnection signal when the detection circuit is disconnected. The control device is connected to the signal output end and is configured to send an alarm signal to a user of the vehicle when the circuit disconnection signal is received. According to the scheme of the invention, when thermal runaway occurs in the battery module, a large amount of high-temperature and high-pressure gas generated in the battery module can damage the detection circuit and break the detection circuit, and the signal output end of the detection circuit can output the circuit break signal in time, so that the control device can send an alarm signal in time, and the response time is shortened.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and more specifically, to a battery system for a vehicle and a vehicle with the battery system. Background technique [0002] With the development of vehicle technology, the requirements for the safety performance of the battery of the vehicle are also getting higher and higher. When abnormal thermal runaway occurs inside the battery system, a large amount of high-temperature and high-pressure gas will be generated. According to the requirements of the latest national standard to be published, the battery pack or system should provide an alarm signal five minutes before the danger occurs in the passenger compartment due to thermal runaway of a single battery cell, so as to remind the occupants in the vehicle to evacuate as soon as possible . [0003] Known battery systems usually use voltage sensors or temperature sensors to detect whether abnormal thermal runaway occurs in the battery...
