Heat Pump and Thermal Management for Efficiency Engineering
A heat pump is a heat transfer system in an electric vehicle that can produce 2-4 kW of heat from 1 kW of electricity, operating as a reversed air conditioning cycle. Instead of generating heat the way a resistance heater does, it collects heat from …

How Does Torque Vectoring Work in Electric Cars?
Torque vectoring is the instantaneous redistribution of power between the wheels and axles of an electric vehicle via software control; since there is no mechanical connection between the motors, this distribution happens faster and more flexibly tha…

How Does Fast Charging Become a Reality with 800 Volt Architecture?
An 800-volt architecture is an electrical system layout that designs the EV's battery pack, inverter, DC-DC converters, and charging units around a nominal voltage of approximately 800 volts. Because it halves the current needed to carry the same pow…

Electric Car Motor Selection: Synchronous, Asynchronous, and Permanent Magnet
Electric cars use three main motor types: permanent magnet synchronous motor (PMSM), asynchronous (induction) motor, and externally excited synchronous motor (EESM). The PMSM offers the highest efficiency and power density, the asynchronous motor sta…
