< Back Heat Pump System Energy-efficient system that controls cabin temperature by transferring heat instead of generating it. EVs often use heat pumps for climate control instead of resistive heaters, improving energy efficiency. A heat pump extracts heat from ambient air or the drivetrain and redirects it to the cabin. It can reverse operation to cool the interior. In cold climates, it reduces energy drain and extends driving range. Integrating the system with battery thermal management further improves overall efficiency. Previous Next Related Diagnostic Guide This topic is part of CHEPQ’s system-level diagnostic framework.
