Temperature control system and temperature control method for battery pack of new energy vehicle

Abstract

The invention discloses a temperature control system of a new energy automobile battery pack and a temperature control method thereof. The temperature control system comprises a controller, and the temperature control system further comprises a power source, a heating element, a temperature measuring component and a control component respectively electrically connected with the controller. The temperature measuring module is used for collecting the external ambient temperature of the battery box and the current temperature of the power battery; The control module is used for controlling the battery box to be communicated with the cab or the battery box to be communicated with the outside; The heating element is used for heating the inside of the battery box; The controller controls the battery box to communicate with the cab or the battery box to communicate with the outside according to the external environment temperature and the current temperature of the power battery; The power supply is used for supplying power to the temperature control system. Based on the system, the temperature control of the power battery can be effectively realized, so that the power battery is at the optimal working temperature, thereby ensuring the effective supply of power, and at the same time, the system has a simple structure, low manufacturing cost, and is convenient to assemble, and in addition, the vehicle dead weight can be effectively reduced, thereby realizing energy conservation and emission reduction.

Description

technical field [0001] The present invention relates to the technical field of automobile control, in particular to a temperature control system for a battery pack of a new energy vehicle, and also relates to a temperature control method for a battery pack of a new energy vehicle including the above temperature control system. Background technique [0002] As the problem of environmental pollution has become increasingly prominent, the new energy industry has developed rapidly in recent years. The state has also issued a series of policies and standards on subsidies for new energy vehicles, supporting the rapid development of the new energy vehicle industry. As the power source of new energy vehicles, batteries directly affect the development of new energy vehicles. Since the battery has high requirements on the working temperature, how to ensure the battery is at the best working temperature has become an important issue in the development of new energy vehicles.

Problems solved by technology

[0004] However, the above-mentioned structure is complicated, the manufacturing cost is high, and the assembly is complicated. At the same time, the self-weight of the vehicle increases, which is not conducive to the energy saving and emission reduction of the vehicle. In addition, when the vehicle is stationary or parked for a long time, it cannot pass the fluid medium in time due to the harsh external environment. Heating or cooling the battery, causing failures such as failure of the vehicle to start
