Equipped with a high-power DC charger in our climatized chassis dynamometer, FEV is able to test charging performance under a range of temperature conditions. During AC and DC charging cycles, we evaluate charge energy/range over time, charge efficiency and usable battery energy. With our own sensor instrumentation, we measure energy losses at various components such as OBC, HV battery and thermal management components. With our charge analyzer equipment and available CAN signals, we can also track the communication between the vehicle and the charging station.
