waiting for 1 minute;
judging whether the temperature difference is less than 2 degrees;
if the temperature difference is more than or equal to 2 degrees; returning to the air conditioner controller to open external circulation, sending air in the vehicle into the vehicle, and exhausting the air in the vehicle;
if the temperature difference is less than 2 degrees; the air conditioner controller sends a power-off request signal, the whole vehicle is powered off, and the frost prevention work is finished.
When the vehicle is locked outside, the air conditioner controller detects the temperature difference between the inside and the outside of the vehicle, if the temperature difference is more than or equal to 2 ℃, a signal for requesting the whole vehicle to be electrified is sent out, and the whole vehicle is electrified at high voltage, so that the electric quantity of the low-voltage storage battery is not consumed in the cooling process.
After the vehicle is powered on, the air conditioner controller opens the external circulation to send cold air outside the vehicle directly into the vehicle and exhaust hot air outside the vehicle, so that the temperature inside the vehicle is basically consistent with the temperature outside the vehicle, no temperature difference exists, and the vehicle glass does not frost.
In the process, the air conditioner controller detects the temperature difference once every 1 minute, if the temperature difference is less than 2 ℃, a power-off request signal is sent out, the whole vehicle is powered off, and the frost prevention work is finished.
The invention is suitable for the electric vehicle with an automatic air conditioner, can solve the problem of frost on glass when the vehicle is parked outdoors in winter in the north, and improves the satisfaction degree of users.
