Information device for a vehicle
First Claim
1. An information device for a vehicle that has an electrical energy store in the vehicle and an apparatus for charging the electrical energy store with electrical energy drawn from a stationary power supply system external of the vehicle, the information device comprising:
- a battery management system for processing and indicating values for electrical variables that include current, voltage and charge when the electrical energy is drawn from the stationary power supply system; and
a vehicle controller in the vehicle to calculate and indicate an amount of electrical energy drawn from the stationary power supply system by using a time information item provided in a vehicle controller.

Abstract
A vehicle has an apparatus (2) for charging an electrical energy store (3) from a stationary power supply system. An existing controller (6) of the vehicle is configured to calculate and indicate an amount of electrical energy drawn from the stationary power supply system by using a time information item provided in the vehicle controller (6). Alternatively, a battery management system (1) is configured to calculate and indicate the amount of electrical energy drawn from the stationary power supply system by using the time information item provided in the existing vehicle controller (6).
