In order to reduce fuel consumption further, the mixing of so-called plug-in type provides the probability charged by exterior source of energy to high-voltage energy storage device.At this, exterior source of energy can be public power supply network, solar power plant and/or wind power plant or the like.
The alternative with the automobile of traditional combustion engine is electric vehicle.Different from motor vehicle driven by mixed power, electric vehicle does not possess the internal combustion engine that can drive automobile.Therefore, in these automobiles, it may be necessary exterior source of energy charge to high-voltage energy storage device.At present, high-voltage energy storage device is generally configured vehicle high-voltage accumulator.
Charge to the vehicle high-voltage accumulator of motor vehicle driven by mixed power or electric vehicle to pass through such as public power supply network, it is necessary to charging device.At present, conventional charging device has the charge-electronics with potential isolation.Generally, in the charging device of automobile, transformator be also satisfied the task of potential isolation except the task of voltage matches.Potential isolation in charging device meets 3 important security functions:
-charging plug be pulled out with the high-tension circuit situation activated under stop and shock by electricity when contacting plug contacts；
-stop the RCD protection switch in the electric utility for being derived to the electric energy of vehicle high-voltage accumulator charging saturated；
-with making zero line and vehicle separately, the insulated monitoring thus made in automobile during charging process becomes possibility.
Summary of the invention
The present invention proposes a kind of charging device without potential isolation for automobile: have the first switchable isolating device, described first isolating device is configured to open and/or close the wire having at least electric current to flow through of the charge cable coupled by charging device with power supply network, in order to sets up or cancels the potential isolation between automobile ground and the zero line of charge cable；Having the second switchable isolating device, described second isolating device is configured to open and/or close at least one circuit vehicle high-voltage accumulator being connected with charging device and/or onboard power system；With there is supervising device, described supervising device be configured to monitoring charging device or automobile malfunction and according to malfunction to first and/or second isolating device transmit adjust signal.
Additionally, the present invention also propose a kind of especially with the charging device according to the present invention without potential isolation to the charging method of vehicle charging, described charging method has following steps: monitoring charging device and the electric fault of automobile；Generate the information about charging device and the malfunction of automobile；When the information about malfunction demonstrates and has fault in charging device and/or automobile, the adjustment signal for opening is transmitted to the first isolating device, described first isolating device is configured to, and opens and/or close the wire having at least electric current to flow through of the charge cable coupled by charging device with power supply network；And/or when the information about malfunction demonstrates and has fault in charging device and/or automobile, the adjustment signal for opening is transmitted to the second isolating device, described second isolating device is configured to, and opens and/or close at least one circuit vehicle high-voltage accumulator being connected with charging device and/or onboard power system.

In another interchangeable structural form, supervising device with automobile exists insulation monitor and the first isolating device couples, wherein said supervising device is configured to the interval by maximum 15 minutes, the adjustment signal for opening is transmitted to the first isolating device in interval preferably to up to 5 minutes, and the result according to insulation monitor (5) transmits the adjustment signal for opening and/or closing to the first and/or second isolating device.If cyclically performing the monitoring to charging device and automobile and using already present insulation monitor in automobile for this, then can abandon special DC Line Fault measuring circuit.The charging device that expense is relatively low can be provided whereby.
In an interchangeable structural form, above two is grouped together for the probability monitoring charging device and automobile.In such structural form, supervising device is connected with DC Line Fault measuring circuit for good and all monitor fault and additionally cyclically inquire the insulation monitor of vehicle interior in addition.This modification provides big as far as possible safety, even if because when of two devices be DC Line Fault measuring circuit otherwise be insulation monitor there is defect time, it is also possible to identify fault.
If it is meaningful, it is possible to arbitrarily structure above combination with one another and expansion scheme.Before that other possible structure of the present invention, expansion scheme and enforcement also include being not explicitly mentioned, the present invention or later in reference to the combination of the feature described in embodiment.At this, especially professional person can also using single aspect as improving or supplementing the corresponding base form adding the present invention to.
Especially, in an interchangeable structural form, it is possible to install sensor in the car extraly, described sensor can detect the external condition that charging device can be correspondingly critical to its possibility made a response.Such as, high air humidity and/or the temperature close to dew point can cause insulation resistance to decline.In order to early identify this point, for instance can arrange and analyze the temperature sensor of the ambient temperature of the humidity sensor measuring humidity or detection automobile.
In another interchangeable structural form, the charging cables being connected with socket by charging device is set, and described charge cable has isolating device in plug, described isolating device is configured to, and opens the wire of charge cable, zero line and earth lead between the fault current at least one and zero line and/or earth lead in described wire during flowing.If adopting the RCD protection switch of oneself in the plug of charge cable, even if then this charge cable can also be switched by no current when charge cable is not connected with automobile.This is such as necessary in the case where there: when but charge cable is connected when not being connected with automobile and when charge cable is such as damaged by hay mover with socket.The disconnection disconnecting and can also being automatically activated the first isolating device of RCD protection switch can be analyzed in supervising device.
The present invention may be used for charging to vehicle high-voltage accumulator at traditional AC socket place, charging to vehicle high-voltage accumulator at three-phase alternating current socket place and charge to vehicle high-voltage accumulator at other power supply place.If the present invention is for charging to vehicle high-voltage accumulator at AC socket place, then the first isolating device in a structural form has at least the two poles of the earth, and a pole is for wire with voltage, and a pole is for zero line.If the present invention is for charging to vehicle high-voltage accumulator at three-phase alternating current socket place on the contrary, then the first isolating device in another structural form has at least 3 poles, being a pole respectively for three wire L1, L2 and L3 with voltage, a pole is for being likely to the zero line installed.
