Abstract

The invention discloses a power battery low-temperature starting emergency heating device based on thermochemical energy storage and a control method thereof. The device comprises a battery pack, an adsorption bed, a liquid storage device, a temperature sensor, a liquid level sensor, a power supply state sensor, a vehicle state sensor and a controller. A heat exchange coil pipe is arranged in thebattery pack, an electric heater and a heat exchange coil pipe are arranged in the adsorption bed and the liquid storage device, the battery heat exchange coil pipe and the adsorption bed heat exchange coil pipe are connected through a heat energy transmission pipeline to form a heat circulation pipeline, the adsorption bed is used for thermochemical adsorption energy storage, and all the sensorsare connected with the controller. The device is suitable for heating automobile power battery components in alpine regions, and can solve the problems of difficult starting, low capacity and reducedstability of the power battery at the low temperature.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to an emergency heating device for low-temperature start-up of a power battery based on thermochemical energy storage and a control method thereof. Background technique [0002] After entering the 21st century, the economy and society develop rapidly, and people's demand for travel continues to increase. At the same time, traditional fossil energy such as petroleum is gradually in short supply, and people's awareness of environmental protection is increasing day by day. In this context, the research and development and manufacture of new energy vehicles have been paid more and more attention by more and more countries, and power batteries are widely used as the main power components of new energy vehicles. [0003] Lead-acid batteries, lithium-ion batteries, nickel-metal hydride batteries, etc. have been widely used in the field of power batteries. However, power bat...
