High-voltage EVs Take Charge — and Fast — at Chinaplas
Automakers are raising the bar for voltage systems in new energy vehicles (NEVs) from 400 to 800 V. According to Joule’s Law, the efficiency of an electric motor increases with a high-voltage system, thus improving driving range and reducing the cost of the battery. Under a high voltage, the motor and battery operate at a significantly higher temperature that requires better thermal management. This means plastics need to possess high…
