Abstract

An electrical and/or hybrid motor vehicle device includes a charging device for the charging of an accumulator device. The charging device includes a first charging unit with a connector element for the charging of the accumulator device, which is provided for energy transfer by means of contacts. The charging device also includes a second charging unit with an energy transfer unit for the charging of the accumulator device, which is provided for a contactless energy transfer. The charging device has a charging electronic system, which is provided at least in part as an integral construction with the first and second charging units.

Claims

1. An electrical or hybrid motor vehicle device, comprising:

a charging device configured to charge an accumulator device, wherein the charging device comprises;

a first charging unit with a connector element configured to charge the accumulator device, wherein the connector element is configured to transfer energy using contacts,

a second charging unit with an energy transfer unit, the second charging unit is configured to charge the accumulator device, wherein the second charging unit is configured to transfer energy in a contactless manner,

a charging electronic system that is an integral system for the first and second charging units, wherein the charging electronic system includes a switching unit configured to switch between the first and second charging units, and

a control or regulation unit configured to detect which one of the first and second charging units is active,

wherein when the first and second charging units are simultaneously active, the control or regulation unit switches the switching unit depending on a charging parameter,

wherein the charging parameter is dependent on a charging state of the accumulator device and an available charging time,

wherein if the available charging time and the charging state of the accumulator device are minimal then the control or regulation unit switches the switching unit to connect the first charging unit with the accumulator device,

and wherein if the available charging time and the charging state of the accumulator device are high then the control or regulation unit switches the switching unit to connect the second charging unit with the accumulator device.

2. The motor vehicle device according to claim 1, wherein the charging electronic system includes a rectifier configured so that an energy transfer can take place using both charging units.

3. The motor vehicle device according to claim 1, wherein the control or regulation unit is configured to connect the accumulator device, via the switching unit, with the active one of the first and second charging units.

4. The motor vehicle device according to claim 1, further comprising:

a control element configured to enable an operator to facilitate a direct selection of at least one of the first and second charging units.
