New energy electric vehicle battery pack current and temperature control system

Abstract

The invention discloses a new energy electric vehicle battery pack current and temperature control system, which comprises a base and a battery control module, wherein a battery pack is fixedly connected to position which is close to the middle of the top of the base, vertical rods are fixedly connected to the positions which are close to the four corners of the top of the base, air supply pipes are fixedly connected to the opposite sides of the two vertical rods, a fixing plate is fixedly connected to the top of the vertical rods, a groove is formed in the bottom of the fixing plate, a fan isfixedly connected to the top in the groove, and the fan is communicated with a first exhaust pipe through an exhaust port formed in the top of the fan. According to the new energy electric vehicle battery pack current and temperature control system, through the design of a voltage detection module, a current detection module, a resistance detection module and a protection system, the voltage, thecurrent and the resistance of the battery pack can be monitored in real time, and once an abnormal condition occurs, a driver can be prompted in time and the power-off protection device is automatically started to provide a good protection function for the battery pack.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a current and temperature control system for battery packs of new energy electric vehicles. Background technique [0002] Electric vehicles refer to vehicles that use electric energy as a power source and are driven by electric motors. They are new energy vehicles, including pure electric vehicles (BEV), hybrid electric vehicles (HEV) and fuel cell electric vehicles (FCEV). Because its impact on the environment is relatively small compared with traditional cars, its development prospects are widely optimistic, but the technology is still immature. Those that typically run on conventional fuel are paired with an electric motor or engine to improve low-speed power delivery and fuel consumption. In the domestic market, gasoline hybrid vehicles are the mainstream of hybrid vehicles, while diesel hybrid vehicles are also developing rapidly in the international market. [0...
