Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

For grid operators, the macro trends in power demand can be easy to predict, and therefore easier to balance. For example, demand will often increase when is it raining or peak during half time of a national televised sporting event. A fuel-based generator cannot turn on quick enough to respond to these types of changes.

and, acting as the link, controls the flow of high-voltage power between the e-motor and the lithium-ion battery (depending on battery voltage between 296 and up to 418 V). In doing so the power electronics convert the direct current (DC) stored in the battery into alternating current (AC) and use this to drive the motor.
