Control device for battery cabin door of alternating current mode-based electric vehicle

Abstract

The invention discloses a control device for a battery cabin door of an alternating current mode-based electric vehicle. The control device comprises a master control CPU (central processing unit), a power supply system power supply voltage stabilization filtering device, an input signal detection and conditioning device, a CAN (controller area network) level conversion device and an output control device; the master control CPU is connected with the power supply system power supply voltage stabilization filtering device, the input signal detection and conditioning device, the CAN level conversion device and the output control device. The control device for the battery cabin door of the alternating current mode-based electric vehicle is capable of stably controlling the battery cabin door, and has strong drive capability; when malfunction and failure are sent out during battery cabin door control, rapid detection can also be performed, and related personnel is reminded in time.

Description

technical field [0001] The invention relates to the field of electric vehicles based on a battery swap mode, in particular to a battery compartment door control device for an electric vehicle based on a battery swap mode. Background technique [0002] As an important prerequisite and basis for the large-scale promotion and application of electric vehicles, the development of electric vehicle charging and swapping technology has attracted widespread attention from all parties. At present, the charging and swapping mode of electric vehicles is dominated by battery swapping, supplemented by charging. In order to meet market demand, major car companies have launched electric vehicle models with swappable batteries. For electric vehicles in battery replacement mode, the control and fault detection of the battery compartment are particularly important. However, the existing battery compartment door control devices often lack fault detection devices. Once a fault occurs, relevant ...
