Method and arrangement for controlling charging of an energy storage system
First Claim
1. Method for controlling charging of an energy storage system in a vehicle comprising an electric machine which is arranged for propulsion of the vehicle, the method comprising:
- initiating the charging upon connection of the energy storage system to an external power supply via connector elements;
transmitting, from the vehicle to the external power supply, a control signal comprising data related to the charging by means of a wireless transmission link;
determining, in a vehicle control unit, whether at least one parameter of the data deviates from a predetermined parameter value and, upon determining that at least one parameter of the data deviates from the predetermined parameter value, terminating transmission of the control signal;
determining, in the external power supply, whether the control signal has not been received;
terminating the charging upon determining that the control signal has not been received;
providing a predetermined modulation upon a requested charging pattern;
determining that the charging supplied to the energy storage system does not comprise the predetermined modulation; and
indicating that the char in of the energy storage system is erroneous upon determining that the charging supplied to the energy storage system does not comprise the predetermined modulationwherein the data related to the charging comprises information related to at least one of the following parameters;
i) a current position of the vehicle;
ii) any occurrence of movement of the vehicle;
iii) the identity of the vehicle;
iv) electrical isolation of the energy storage system;
v) a status of connector elements of components of the vehicle;
vi) a charging current;
vii) a charging voltage; and
viii) a temperature of the connector elements.

Abstract
A method is provided for controlling charging of an energy storage system in a vehicle including an electric machine which is arranged for propulsion of the vehicle. The method includes initiating the charging upon connection of the energy storage system to an external power supply via connector elements; and transmitting, between the vehicle and the external power supply, a control signal including data related to the charging by a wireless transmission link. The method furthermore includes evaluating whether the control signal is received; and terminating the charging in the event that the control signal is not received. An arrangement for controlling charging of an energy storage system is also provided.

9. An arrangement for controlling charging of an energy storage system in a vehicle comprising an electric machine which is arranged for propulsion of the vehicle, the arrangement comprising
an external power supply arranged for initiating charging upon connection of the energy storage system to the external power supply via connector elements, and a transmitter unit and receiver unit for wirelessly transmitting a control signal comprising data related to the charging from the vehicle to the external power supply, wherein the arrangement is configured for determining, in a vehicle control unit, that at least one parameter of the data deviates from a predetermined parameter value and, upon determining that at least one parameter of the data deviates from the predetermined parameter value, terminating transmission of the control signal, for determining, in the external power supply, that the control signal has not been received in the receiver unit, and for terminating the charging upon determining that the control signal has not been received; -
wherein the data related to the charging comprises information related to at least one of the following parameters; i) a current position of the vehicle; ii) any occurrence of movement of the vehicle; iii) the identity of the vehicle; iv) electrical isolation of the energy storage system; v) a status of connector elements of the vehicle; vi) a charging current; vii) a charging voltage; and viii) a temperature of the connector elements, a wherein the control unit comprises a modulation unit for applying a predetermined modulation upon a requested charging pattern and an evaluation unit for determining whether the charging supplied to the energy storage system comprises the predetermined modulation and indicating that the charging of the energy storage system is erroneous upon determining the charging supplied to the energy storage system does not comprise the predetermined modulation. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
