Vehicle-mounted battery heat management system and method of new energy vehicle

Abstract

The embodiment of the invention discloses a vehicle-mounted battery heat management system and method of a new energy vehicle. The vehicle-mounted battery heat management system of the new energy vehicle comprises an environment information sensor, a vehicle-mounted remote information processor and a vehicle control unit, wherein the environment information sensor is used for detecting environment information of the new energy vehicle; the vehicle-mounted remote information processor is used for accessing a storage medium to obtain a heat insulation mode or receiving a remote message containing the heat insulation mode, determining a wake-up period on the basis of the environment information, waking up the vehicle control unit on the basis of the wake-up period and transmitting the heat insulation mode to the vehicle control unit; and the vehicle control unit is used for outputting a vehicle-mounted battery heat management instruction generated on the basis of the heat insulation mode after being waked up. According to the vehicle-mounted battery heat management system of the new energy vehicle, by considering the environment information, heat management can be preferably performed, the service life of a battery can be prolonged, heat management can also be performed in the case that the whole vehicle is stationary or static, and a working condition preferably satisfies use requirements.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of new energy vehicles, in particular to a thermal management system and method for an on-board battery of a new energy vehicle. Background technique [0002] Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important way to solve the energy crisis and environmental degradation. Hybrid vehicles take into account the advantages of pure electric vehicles and traditional internal combustion engine vehicles at the same time. On the premise of meeting the requirements of vehicle power and mileage, it effectively improves fuel ec...

[0004] However, this processing method only considers the temperature limit of the battery system, motor and other systems, and does not consider environmental conditions such as ambient temperature and geographical location, and the thermal management efficiency is not good.

[0005] Moreover, in the current prior art, thermal management is only performed during driving and charging, and thermal management is not performed when the vehicle is stationary or static, which is inconvenient to use
