Abstract

An indicator system for a vehicle having an electric motor and a rechargeable battery can include an indicator having a body with a first end and a second opposite end. The body can include an indicator area defining a plurality of contiguous indicator segments therebetween. Each indicator segment can be configured to provide a separate status indication of at least one of a state of charge of the rechargeable battery, a state of a user specified vehicle feature condition, and a fault condition associated with charging of the rechargeable battery. The indicator can be mounted to a vehicle structure about the first end such that the second end extends away from the vehicle structure and the indicator area is externally visible relative to the vehicle from multiple viewpoints beyond a periphery of the vehicle.
