Energy Storage System for an Electrically Driven Vehicle

摘要

An energy storage system is provided for an electrically driven vehicle, having a first energy storage unit which provides sufficient basic electric power to operate at least one electric motor of the vehicle. The first energy storage unit is connected to the electric motor of the vehicle via an inverter. A connection is provided via which at least one additional energy storage unit can be connected parallel to the first energy storage unit. In another variant, an energy storage system for an electrically driven vehicle has three energy storage units, each of which has at least one energy store. The three energy storage units are connected such that each energy storage unit provides one phase of a three-phase alternating current for an electric motor of the vehicle. The individual energy storage units can be expanded by adding additional energy stores.
