Electric conversion system of pure electric vehicle and electric vehicle

Abstract

The invention relates to an electric conversion system of a pure electric vehicle and an electric vehicle, wherein the electric conversion system comprises a vehicle body fixing part, a locking mechanism and a controller; the locking mechanism is used for fixing a battery box body and rotationally locking / unlocking the battery box body on the vehicle body fixing part, and the locking mechanism isprovided with two extension shafts extending outwards; magnetic elements are fixed at the near end parts of the two extension shafts, wherein the magnetic pole directions of the magnetic elements areconsistent with the length directions of the extension shafts; a Hall sensor corresponding to the position of the magnetic element when the locking mechanism is in a locked state is arranged on the vehicle body fixing part; the controller acquires a signal of the Hall sensor to detect the locking / unlocking state in real time. According to the electric conversion system of the pure electric vehicle, a driver and passengers can directly obtain the locking and unlocking states of the locking mechanism according to the detection information of the controller, and the driving safety can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of rapid replacement of battery packs of electric vehicles, in particular to battery replacement systems for pure electric vehicles and electric vehicles. Background technique [0002] With the current rapid development of electric vehicles, the electrification of vehicle energy power systems is the only way to solve the current energy crisis and environmental crisis in the automotive industry. At present, there are two charging modes for electric vehicles, one is fast charging and the other is fast battery replacement. As the second power supply, the battery pack needs to be installed in the electric vehicle. Since the battery pack needs to be replaced or charged, in the prior art, the battery pack is usually installed in the electric vehicle in a detachable way by unlocking. However, the driver Personnel can only obtain the information of whether the battery pack is locked and installed in the e...
