[0003] The existing technology uses electric heating to heat the battery. Using this method is easy to heat up too fast, and the temperature is too high. When the battery is low temperature, the temperature difference between the heating sheet and the module and the battery cells in the module is too large. Has a certain impact on battery life

Abstract
Embodiments of the present invention provide a heat exchange structure and a heat exchange control method, which relate to the technical field of heat exchange. The heat exchange structure includes a control unit, a first temperature sensor, a heat exchange component and a circulation component. The circulation component is used to connect with the product; the heat exchange component communicates with the circulation component and is used to exchange heat for the heat exchange medium in the circulation component; the first The temperature sensor is set at the product to detect the product temperature data of the product; the control unit is used to receive the product temperature data, and when the product is in the first temperature range, the control cycle component starts or the control cycle component and the heat exchange component start simultaneously , so that the heat exchange medium in the circulation component circulates to exchange heat for the product. In the present invention, the circulating flow of the heat exchange medium in the circulation component can evenly exchange heat for the product, so that the whole product can be kept within a stable temperature range, which is safe and reliable, and prolongs the service life of the product.
Description
technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchange structure and a heat exchange control method. Background technique [0002] In current new energy vehicles (EV / HEV / PHEV) and other electric vehicles where batteries provide the main energy, the temperature of the battery greatly affects the performance of pure electric drive and the energy and time of discharge. In addition, from the perspective of power battery life, a more suitable temperature and better consistency of the battery pack can maximize the life of the battery. Then the thermal management of the power battery is particularly important. [0003] The existing technology uses electric heating to heat the battery. Using this method is easy to heat up too fast, and the temperature is too high. When the battery is low temperature, the temperature difference between the heating sheet and the module and the battery cells in the module is too large. I...
