System for determining and calculating the work done by a mobile electrical machine at an energy supply station
First Claim
1. A system for determining and accounting for the service of a mobile electrical machine provided with an electrical energy storage unit including a battery, said system comprising:
- an electric-current supply network;
a pulse generator connected between said network and said machine for generating a time-spaced sequence of accounting pulses representing at least the value of electrical energy delivered to said machine, said pulse generator being constructed and arranged to delliver a train of pulses of a cadence corresponding to a variable electric tariff;
a pulse counter connected to said pulse generator for counting pulses derived from said pulse generator over a time interval corresponding to that for which said machine is connected to said network;
evaluating means on said machine responsive to the count of said counter and connected thereto for registering the value at least of electrical energy supplied to said machine; and
a current supply path connecting said network to said energy-storage unit and including a battery charger, said evaluating means including a deductor, said deductor being a credit-balance deductor settable to a predetermined value from which a value corresponding to the count in said counter is deducted during the charging of said battery.

Abstract
A system for determining and accounting for the service of an electric vehicle provided with a battery which has an electric-current supply network, a pulse generator connected between this network and the vehicle for generating a time-spaced sequence of accounting pulses representing at least the value of electrical energy delivered to the vehicle, a pulse counter connected to the pulse generator for counting pulses derived from the pulse generator over a time interval corresponding to that for which the vehicle is connected to the network, and an evaluator in the form of a deductor on said machine responsive to the count of the counter and connected thereto for registering the value at least of electrical energy supplied to said machine.
