The BMS sends charging current to the charger according to a normal charging mode, the SOC of the battery is charged to a set state of charge, for example, 90%, the BMS limits charging power after the SOC value of the battery reaches 90%, the battery is charged with a set small current M (M is less than or equal to 5A), and the battery is prevented from being charged in Y hours.
When the time reaches a first set time before the vehicle using time is set, for example, the time is compared with the time after X-1.5 hours from the time of plug-in charging, the BMS sends a starting instruction to the air conditioner, the air conditioner heats or cools according to the starting instruction and the reserved temperature in the vehicle of the vehicle-mounted monitoring terminal, and sends the working power of the air conditioner to the BMS in real time, the BMS adjusts the output charging power of the charger to be the same as the working power of the air conditioner, so that the SOC value of the battery is kept to be the SOC value at the time of X-1.5 within the set time after X-1.5, and the set time is the difference value between the first set time and the second set time.
5. And at a second set moment before the set vehicle-using time, controlling and adjusting the charging power to enable the battery to reach a full charge state, stopping charging and turning off the air conditioner.
At a second set time before the set vehicle using time, the BMS controls and adjusts the charger, so that the charging power is increased, the vehicle is ensured to enable the battery to reach a full charge state before the reserved vehicle using time, and the air conditioner is turned off.
For example, when the time reaches X-0.5 hours from the time of plug-in charging, the BMS adjusts the charging power to the maximum value until the SOC reaches 100%, and sends a shutdown instruction to the air conditioner, and after the air conditioner is shut down, the BMS sends a charging stop instruction to the charger, and the charging is finished.
In conclusion, the heating device and the heating method have the advantages that the full power battery is ensured, meanwhile, the vehicle is heated before departure, the driving range of the vehicle is ensured, and the comfort level of the vehicle is improved.
