Problems solved by technology
The electric vehicle air conditioner mentioned above does not have a power distribution system, and consumes a lot of power during operation, generally accounting for about 20% of the total power consumption of electric vehicles, which affects the cruising range of electric vehicles
Especially when an electric vehicle is overtaking or climbing a hill, the power consumption of the electric vehicle increases and the voltage of the battery of the electric vehicle drops. If the power consumption of the electric vehicle air conditioner remains unchanged at this time, the electric vehicle may not be able to drive normally
