Abstract

The invention provides charging control method, device and equipment and an electric vehicle. The charging control method comprises the steps that power supply status information is obtained; a whole vehicle status signal collected by an electric vehicle management device is obtained; and if the power supply status information and the whole vehicle status signal meet the charging conditions, a charging control signal is sent to a vehicle-mounted charger, and the vehicle-mounted charger charges the vehicle. According to the charging control method, the slow-charging control section of the electric vehicle is simplified, uniform dispatch is conducted, and the charging reliability and safety of the electric vehicle are improved; the design of the vehicle-mounted charger can be simplified, the vehicle-mounted charger is simplified into a power part from a part in charge of control and power in the prior art, the cost and development difficulty of the vehicle-mounted charger are reduced, consistent development of all part developers is facilitated, and integrated development of a power part of the vehicle-mounted charger is facilitated.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a charging control method, device and equipment and the electric vehicle. Background technique [0002] The current mainstream charging methods for electric vehicles are divided into DC fast charging and AC slow charging, among which AC slow charging is divided into single-phase charging and three-phase AC charging; electric vehicles use AC slow charging to complete the entire charging process, and AC charging piles ( Or cable control and protection device), charging gun, vehicle slow charging harness, on-board charger, vehicle controller (VCU), battery management system (BMS), and power battery must participate in the entire charging process at the same time. [0003] Different OEMs take different control routes. Some OEMs use VCU as the main control unit of the slow charging link, and the charging pile (or cable control and protection device), on-board charger, BMS, and power ...
