A method and a device for controlling vehicle charging, a program, a medium, and a vehicle is provided. The method by acquiring a current connection state of a telematics box in the vehicle and the server when a charging gun of a vehicle is determined in a connection state; and recording a first duration of the offline state when the current connection state is determined in an offline state, and controlling the vehicle charging according to the first duration. In this way, when it is determined that the current connection state is in the offline state, the vehicle charging can be controlled according to the duration of the offline state, which can effectively avoid the problem of charging failure due to network connection failure during the reservation charging process, the reliability of vehicle reservation charging is improved, and thus the vehicle user experience is effectively improved.

Method and device for controlling vehicle charging and vehicle

The present disclosure provides a method and system for determining a pure electric available power and a vehicle, the method being applied to a vehicle including a fuel cell, the vehicle further including a battery pack and a motor, the fuel cell and the battery pack being electrically connected to the motor, wherein the method includes: monitoring a current travelling state of the vehicle and a current on-off state of the fuel cell; acquiring a maximum peak power outputted by the motor, a maximum output power of the battery pack and a starting-up power of the fuel cell; and according to the current travelling state, the current on-off state of the fuel cell, the maximum peak power, the maximum output power and the starting-up power, determining the pure electric available power.

Pure electric available power determination method and system, and vehicle

The vehicle includes a battery pack. When the battery pack is charged by using a charging gun of a charging pile, battery pack is charged according to a smaller value between a first charging current upper limit value of a charging device and a second charging current upper limit value of the battery pack, so that the charging efficiency is improved to the greatest extent, and the charging time is shortened on the premise of ensuring safety, and a situation that the charging time is prolonged as the charging current is set to be too small is avoided; and when the battery pack is charged by using an on-board charging gun, the battery pack is charged according to a smallest value among the first charging current upper limit value of the charging device, the second charging current upper limit value of the battery pack, and a preset charging current value.
