Abstract
The charging circuit is for charging an auxiliary battery of a vehicle which is driven by an electric motor supplied with current by a main battery through a supply circuit comprising a device for chopping the battery voltage during the vehicle starting and braking stages. This charging circuit comprises a transformer whose primary winding is inserted in the aforementioned supply circuit of the motor and supplied with current by the chopper device. The secondary winding of the transformer is connected to supply current to the auxiliary battery through a rectifier device.
