Abstract
A method for improving the performance of a traction battery during a driving start phase of an electric vehicle. A driving start point in time at which the driving start phase begins is provided. A temperature of the traction battery is detected. This temperature is compared with a minimum operating temperature, and the traction battery is heated if the comparison reveals that the temperature of the traction battery is below the minimum operating temperature. The heating takes place with a temperature increase which provides a temperature of the traction battery at the driving start point in time, which is no lower than the minimum operating temperature.

11. A method for improving performance of a traction battery during a driving start phase of an electric vehicle, comprising:
-
providing a driving start point in time at which the driving start phase begins; detecting a temperature of the traction battery; comparing the temperature with a minimum operating temperature; and heating the traction battery to increase the temperature of the traction battery to a temperature which is no lower than the minimum operating temperature at the driving start point in time, if the comparison reveals that the temperature of the traction battery is below the minimum operating temperature. - View Dependent Claims (12, 13, 14, 15, 16)

17. A charge control device to charge a traction battery, comprising:
-
a temperature signal input; a comparator connected to the temperature signal input, the comparator being equipped to compare a temperature signal applied at the temperature signal input with a predefined minimum operating temperature; a time input; a charging signal output; and a state-of-charge ascertaining device to detect a state of charge of the traction battery; wherein the charge control device is equipped to estimate based on the state of charge, a charging time necessary for fully charging the traction battery, starting from the detected state of charge, the charge control device equipped to subtract the charging time from a time which is applied to the time input and represents the driving start point in time, and to deliver a charging signal for a charging period at the charging signal output, which starts at or before the driving start point in time minus the charging time. - View Dependent Claims (18, 19, 20)
