Abstract
The invention relates to a device (1) for charging a starting battery in a vehicle. The device comprises a number of chargeable emergency battery units (3a, 3b), control circuits for controlling a first charging process for charging the starting battery (2) and for controlling a second charging process for charging the emergency battery units (3a, 3b), and connecting devices (5) for electrical connection to a circuit in which the starting battery (2) is included. The control circuits comprise a checking device (6), arranged for measuring the starting battery'"'"'s voltage and a voltage for at least one of the emergency battery units, and arranged for controlling at least one of the first and the second charging processes as a function of at least these voltages. In addition the control device (6) comprises a first temperature sensor device (51) for measuring a temperature at or near an emergency battery unit, and is arranged for controlling at least one of the first and the second charging processes as a function of this temperature.
