Chapter 5: Electric Vehicle Powertrain Architecture and Configurations
Abstract : EV powertrains convert electrical energy to motion using components like batteries, motors, and inverters, with key architectures being Battery Electric (BEV) for pure electric, Hybrid (HEV/PHEV) combining motor with an engine, and Fuel Cell (FCEV) using hydrogen; configurations range from simple single-motor setups to complex multi-motor, all-wheel-drive systems , optimizing efficiency and performance. Core Components Battery Pack : Stores electrical energy (DC). Power Electronics (Inverter/Controller) : Converts battery's DC to AC for the motor and controls motor speed/torque. Electric Motor : Converts electrical energy into mechanical rotation (torque). Transmission : Single-speed gearbox or reduction drive to wheels. DC-DC Converter : Steps down high voltage to power vehicle accessories (12V). On-Board Charger : Converts AC from the grid to DC for battery charging. Main EV Powertrain Architectures Battery...
