Abstract
Most battery electric vehicles currently in use have primary and/or auxiliary e-axles that integrate the e-motor, transmission, and inverter. However, this results in lower efficiency due to losses at low speeds. New designs, such as the skateboard architecture, address this challenge, and enable cost-effective and efficient electric vehicles.
