Abstract

The invention discloses a power supply system and method of an electric vehicle power battery monitoring device. According to the system, a solar cell panel generates electric energy under the sun illumination when the vehicle is placed outdoors and is in a flameout parking state and there is an illumination condition, the electric energy is supplied to a starting storage battery for charging through a solar controller, and meanwhile, the electric energy is supplied to a battery management system; and a sleep mode of the battery management system is converted into a working mode, and the power battery is monitored in real time by collecting and monitoring a voltage signal and a temperature signal of the power battery.

Description

technical field [0001] The invention relates to the technical field of thermal runaway monitoring of a power battery of an electric vehicle, in particular to a method for monitoring and supplying power for a storage battery and a power battery through solar power generation of an electric vehicle. Background technique [0002] New energy vehicles are currently in a stage of rapid development, and their universality will become an inevitable trend in the future development of the automotive industry. As a key component of new energy vehicles, the safety of power batteries has attracted extensive attention. In recent years, safety accidents of electric vehicles caused by battery thermal runaway have occurred frequently. When the battery thermal runaway will cause a sharp change in battery temperature, gas smoke will be generated at the same time, and eventually catch fire or even explode. [0003] Especially when the electric vehicle is turned off and the battery management s...
