Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
196 words
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.
Claim 2
Independent Claim
196 words
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.
Claim 3
Dependent Claim
