Patent Images
1. A charging device for charging each of a plurality of different types of vehicle accumulators, the charging device comprising:
- a control unit configured to execute a plurality of different predetermined charge programs corresponding with the plurality of different types of vehicle accumulators, each predetermined charging program being executable by the control unit to control charging of a respective type of vehicle accumulator; and
an accumulator recognition unit configured to, during connection of a particular type of a vehicle accumulator to the charging device via a communication link;
receive, from the vehicle accumulator via the communication link, accumulator identification information indicating the particular type of vehicle accumulator connected to the charging device; and
identify the particular type of vehicle accumulator currently connected to the charging device based on the received accumulator identification information; and
wherein the control unit is further executable to;
access, from the vehicle accumulator via the communication link, a particular predetermined charge program corresponding with the particular type of vehicle accumulator identified by the accumulator recognition unit;
wherein the particular predetermined charge program is transferred to the control unit in cryptographically encrypted form;
in response to accessing the particular predetermined charge program from the vehicle accumulator in cryptographically encrypted form, automatically request a corresponding key for decryption from a server associated with a manufacturer of the particular type of vehicle accumulator;
obtain the decryption key from the server associated with the manufacturer of the particular type of vehicle accumulator, and use the decryption key to decrypt the predetermined charge program received from the vehicle accumulator; and
execute the particular predetermined charge program to control charging of the particular type of vehicle accumulator.

Abstract
A vehicle accumulator connected to a charging device is charged by controlling a configurable charge program executed by a control unit of the charge device. The configurable charge program is obtained from a charge program memory, so that the vehicle accumulator can be charged in an optimal manner with an individual charging characteristic.

8. A method for charging each of a plurality of different types of vehicle accumulators by a charging device using a plurality of different predetermined charge programs corresponding with the plurality of different types of vehicle accumulators, the method comprising, for each of the different types of vehicle accumulators:
-
connecting a particular type of vehicle accumulator to the charging device via a communication link; receiving, at an accumulator recognition unit of the charging device, from the vehicle accumulator via the communication link, accumulator identification information indicating the particular type of vehicle accumulator connected to the charging device; identifying, by the accumulator recognition unit, based on the received accumulator identification information, the particular type of vehicle accumulator; obtaining, by a control unit of the charging device, from a charge program memory of the vehicle accumulator via the communication link, a particular predetermined charge program, from the plurality of different predetermined charge programs, that corresponds with the particular type of vehicle accumulator identified by the accumulator recognition unit; wherein the particular predetermined charge program is transferred to the control unit in cryptographically encrypted form; in response to obtaining the particular predetermined charge program from the vehicle accumulator in cryptographically encrypted form, automatically requesting a corresponding key for decryption from a server associated with a manufacturer of the particular type of vehicle accumulator; obtaining the decryption key from the server associated with the manufacturer of the particular type of vehicle accumulator; using the decryption key to decrypt the charge program received from the vehicle accumulator; and executing the particular predetermined charge program by the control unit of the charging device to charge the particular type of vehicle accumulator. - View Dependent Claims (9, 10)
