Accompanying drawing explanation
Explanation with reference to the accompanying drawings and is below set forth embodiments of the invention further, wherein:
Fig. 1 shows the flow chart of the embodiment according to method of the present invention; And
Fig. 2 shows the embodiment according to the battery management system under the state being connected with the charging wiring of motor vehicle of the present invention.
Embodiment
Figure 1 illustrates the flow chart of the embodiment of the method for charging according to the direct voltage of the accumulator for monitoring equipment motor-car of the present invention.The method comprises the accumulator of motor vehicle, its by close at arrange in charging conductor for direct voltage charging quick charge contactor and charging station be that conductivity is attachable.In other words, the method comprises the accumulator of motor vehicle, it is connected with charging station by charging conductor, wherein quick charge contactor is set in charging conductor, can be cut off by this quick charge contactor charging conductor, namely make the charging of accumulator become the charging and may can interrupting accumulator.The input voltage putting on charging conductor is measured in the first method step S1 of the method.In other words, measure in the first method step S1 or obtain the input voltage that provided by charging station, the accumulator of motor vehicle is that conductivity is connected with this charging station by charging conductor and quick charge contactor.In the second method step S2, implement direct voltage inspection, wherein determine voltage swing and the polarity of input voltage.Also determine in the second method step, be positioned at charging conductor place and the input voltage provided by charging station has much, or input voltage has any symbol.
In third method step, when the determined voltage swing of input voltage is positioned at the polarity of predetermined voltage range and input voltage corresponding to predetermined polarity chron, closed quick charge contactor.In other words, in the third method step S3 of the embodiment of method according to the present invention, as long as the size of input voltage is higher than lower voltage border and lower than flanging circle that powers on, and input voltage has predetermined symbol, the polarity of this symbol also corresponds to predetermined polarity, then the charging of the accumulator of motor vehicle is possible.In the 4th method step S4 of the method, as long as the polarity that the voltage swing of determined input voltage is not positioned at predetermined voltage range or input voltage does not correspond to predetermined polarity, then disconnect quick charge contactor.In other words, in the 4th method step S4 of the embodiment of method according to the present invention, as long as the size of input voltage is lower than lower voltage border or higher than flanging circle that powers on, or input voltage has the symbol different from predetermined symbol, the polarity of this symbol does not correspond to predetermined polarity yet, then the charging of the accumulator of motor vehicle is interrupted by disconnecting quick charge contactor.
In this embodiment, the pure digitlization exemplarily realizing the input voltage obtained in the second method step S2 performing direct voltage inspection.In other words, the input voltage of simulation or the input voltage curve of simulation be converted in this embodiment numeral, corresponding to the numerical value of instantaneous analog input voltage value.Be verified in the scope that the value of this numeral is checked at the direct voltage of the method subsequently.
In the embodiment of the method, in the step performing direct voltage inspection, whether the input voltage of check digit exists the zero crossing of this input voltage.Change the numerical value of the numeral of the input voltage corresponding to simulation, such as its symbol, will cause the zero crossing in input voltage, and this can infer the existence of the alternating voltage as input voltage at charging conductor place.In this case, this represent when when correspond to simulation input voltage numeral value in the inspection of affirmative of existence of this zero crossing, disconnect quick charge contactor in the embodiment in accordance with the invention and cut off the DC charging of accumulator.In the method for this embodiment, exemplary also comprising obtains the size of electric current that flows through in charging conductor of S5 and the step of flow direction purely.In other words, in the embodiment of the method, obtain S5, the direction that the electric current flowing through charging conductor has much and this electric current to flow through.This represents, whether electric current flows into accumulator or flow out from accumulator.
In addition, according to method of the present invention in this embodiment, as long as determine the commutation of the electric current flow through in charging conductor, then the interruption S6 of the step of the disconnection of quick charge contactor and the direct voltage charging of accumulator is also comprised.Electric current commutation in charging conductor can be derived in the charging putting on charging conductor under-voltage and therefore derive input voltage too small the charging for accumulator.This points out again the mistake in charging station, disconnects quick charge contactor and interrupt the charging of accumulator in this embodiment therefore in the scope of method according to the present invention as the reaction commutated to electric current.
Continue in this embodiment and implement concurrently to measure S1 put on charging conductor input voltage, perform direct voltage inspection S2 and obtain the size of electric current and flow direction that S5 flows through in charging conductor.But also can implement according to method of the present invention, it also comprises other method step, and multiple method step performs with other order in the method.
