Porsche cayenne Electric’s Battery Cooling System Demands Notable Energy
BUCHAREST, Romania – The new all-electric Porsche Cayenne requires a battery cooling system comparable to the power draw of 100 household refrigerators, according to a report by PiataAuto.md.this substantial energy demand raises concerns about overall efficiency despite the shift to electric powertrains.
While Porsche is implementing an smart system designed to preemptively reduce cooling power when not needed, energy losses throughout the system – including cooling, power conversion, and transmission – are estimated to reach 32-40% without considering wireless charging. Adding cabin heating in winter could push total energy loss alarmingly close to 50%, mirroring the efficiency of traditional combustion engines – a key reason for the automotive industry’s move towards electrification. The new Cayenne boasts a rapid charging capability, reaching 80% charge in just 16 minutes via a 400kW charging station, and offers the convenience of wireless home charging, though the latter introduces further energy loss. Porsche aims to balance performance and battery longevity through robust cooling, but this comes at the cost of increased auxiliary energy consumption, potentially impacting the anticipated 85-90% energy efficiency typically associated with electric vehicles.
