Embodiment Construction

[0038] figure 2 A first specific embodiment of the motor vehicle charging device of the invention is shown.

[0039] The device comprises a charging socket 208 and a first electrical energy store 200 called a traction battery.

[0040] Charging socket 208 enables the vehicle to be connected to a power distribution network external to the vehicle.

[0041] The traction battery 200 is capable of powering an electric motor (not shown) by means of an inverter (not shown) to drive the drive wheels (not shown) of the vehicle. The traction battery 200 sends direct current, for example using lithium-ion technology. The voltage at the terminals of the traction battery 200 is greater than 36V, typically less than 400V, for example in the 180V to 260V operating range. The maximum voltage of the traction battery 200 is greater than 50V.

[0042] A second electrical energy store 202 , called an auxiliary battery, is installed in the vehicle for powering the lower power consuming electr...

Abstract

The invention relates to a charging device for a motor vehicle, said charging device comprising an electrical connection part (208) which is an interface for connection to a power distribution network external to the vehicle. The charging device also includes: a first electric energy storage (200), the maximum voltage of the first electric energy storage at its terminal is greater than 50V; and a first voltage converter (206), the first voltage converter is suitable for Energy is transferred between the electrical connection part (208) and the first electrical energy storage (200). The rated power at the terminal post of the electrical connection part (208) is less than 2300W.

Description

technical field [0001] The invention relates to a charging device and a method for an electrical energy store of a motor vehicle, as well as a motor vehicle provided with such a charging device. [0002] The present invention is in the field of "plug-in" vehicles, such as rechargeable electric or hybrid vehicles. Background technique [0003] A vehicle is referred to as a "plug-in" vehicle which comprises at least one electrical energy store (hereinafter also referred to as battery) which can be charged via a connection to an electrical distribution network external to the vehicle. The power distribution network is, for example, a domestic grid providing alternating current at a voltage of 110V or 230V. [0004] Batteries generally include electrochemical cells of all technological types, or capacitors. These electrochemical cells or capacitors are reassembled into one or more modules and connected in series or in parallel with each other. [0005] Plug-in vehicles typica...
