Optimized HVAC Systems for EVs
For EV OEMs, efficient HVAC system is a strategic priority more than mere technical requirements. It is because HVAC plays a vital role, influencing, driving range, passenger comfort and compliance.
Overview
An HVAC system consists of Refrigeration system under the hood and airflow distribution system inside the cabin.
An efficient HVAC system reduces energy consumption from the battery pack which in turn can enhance the driving range by 20-30%.
