Lattice, thus this voltage transformation module can guide the reality output of motor, for example, the reality output of motor may be of about
100kW, the mode of guiding is identical with the mode of the reality output guiding for the external power source charging for battery.
Content of the invention
The purpose of the present invention is therefore to provide a charging system being used for charging to automobile batteries, and it includes a two-way charging
Controller, this two-way charge controller has benefited from its circuit design, simply uses the widget that size meets the requirements, and this just means
, this charging system with save space and can have cost-benefit mode and produces.Further, in the system of this charging system
In making, this two-way charge controller includes less power semiconductor, thus simplifying the manufacture of this charging system.
The present invention reaches this purpose by the described charging system for charging to automobile batteries.
Therefore it is required that protection is a charging system being used for charging to automobile batteries, this charging system includes at least one turn
Parallel operation, an electric power system charging inlet and at least one first switch unit, this transducer is used for handing over one during battery charges
Stream voltage conversion become a DC voltage and powered by battery make a motor operation during a direct current voltage conversion is become one
Alternating voltage, this electric power system charging inlet is used for connecting external power source to this transducer.This first switch unit is used for breaking
Open being conductively connected between this transducer and this motor.
Thus, the charging system of the present invention is distinguished for a two-way charge controller, this two-way charging control
Device processed is connected directly to this battery by one the 3rd switch element in interruptable mode, and is designed as in battery charging process
The middle input voltage reducing from this external power source simultaneously raises from this battery for the input voltage charging to an electric capacity,
This electric capacity is parallel between this two-way charge controller and this transducer.Further, this two-way charge controller have including
One charging circuit of this battery, this charging circuit independent of the operation circuit being run this motor by this battery and is designed
For charging to this battery and this electric capacity, this charging circuit includes one first positive conductor and a negative conductor.

Transducer 2a and 2b respectively has the series circuit of three settings parallel with one another, and each series circuit is connected in series by two
Chopper 7 form.Each chopper includes a diode 8 in parallel with an audion 9.
This motor 3 is connected between the chopper being connected in series, thus being connected with two transducer 2a and 2b.This electric capacity 4
It is connected in parallel with transducer 2a and 2b, this two-way charge controller 5, this battery 6.
Electric power system charging inlet 10 is connected to chopper 7 and the motor 3 that each two of the first transducer 2a is connected in series
Between node at.
Before charging process, including this first switch of two switch elements or switch 11a and 11b as shown in Figure 1
Unit connects in such a way, thus interrupting or disconnecting (switching off) this motor 3 and this electric power system charging inlet
Being conductively connected between 10 or this first transducer 2a.In whole charging process, the state of this first switch unit 11a, 11b
Also keep constant, thus when this battery 6 is charged by the electric energy from external power source (not shown), this motor 3 will not pass through
Electric current.Thus, it is to avoid this motor 3 is driven in charging process and automobile starts the risk of movement.
This two-way charge controller 5 via the charging circuit with positive conductor 12a, a 12b and a negative conductor 13 connect to
This battery 6 and this intermediate circuit electric capacity 4.This positive conductor 12a, 12b include one first wire branch road or the first conductor part 12a and
One second conductor part 12b, this first wire branch road or the first conductor part 12a to this electric capacity 4 of major general connects and two-way fills to this
Electric controller 5, this second conductor part 12b connects this two-way charge controller 5 to the positive pole 6a of this battery.As shown in figure 1,
Negative conductor 13 corresponds to the negative conductor running circuit.
Preferably, this charging circuit is used for being charged to this electric capacity 4 using the electric energy of this battery 6 or utilizes this external power source
Electric energy charge to this battery 6.
In contrast, the operation circuit independent of this charging circuit sends from battery 6, and this operation circuit includes connecting extremely

Or should when charging, this second switch unit 15 disconnect this operation circuit.
If this switch 15 or this second switch unit 15 close, thus allowing this operation circuit turn-on, thus realizing being somebody's turn to do
Battery 6 discharges to drive this motor 3.As a result, only when wanting to this motor 3 supply of electrical energy, this operation circuit just meeting
Guiding electric current flow to this motor 3.
As shown in figure 1, this battery 6, this transducer 2a, 2b or this pair of transducer 2, and this motor 3 all with this operation circuit
It is connected.
It is contemplated that, this two-way charge connector 5 can be used as this battery 6 a ingredient.
Fig. 2 shows a part for the on-off circuit of charging system 1 of the embodiment of the present invention 2.Only give in the present embodiment
Go out a transducer 2a, because it has same design with the transducer 2a in Fig. 1, here no longer specifically describes.In this
Between circuit capacitance 4 is same and this two-way charge controller 5 and this battery 6 parallel connection.
This two-way charge controller 5 also has two choppers 7, and each chopper includes in parallel with an audion 9
Diode 8.Additionally, a pre-charge circuit is connected between two choppers 7 of this two-way charge controller 5, this precharge

, this second switch unit 15 includes two switch element 15a and 15b or two switch 15a and 15b, or can disconnect switch
15a and 15b, so that electric current cannot flow through this operation circuit, thus enabling or closing the 3rd switch element 22.With this side
Formula, electric current can flow to this coil 21 by the positive conductor through this charging circuit, and flows to forward this pre-charge circuit, wherein this coil 21
An interim electromagnetism magnetic memory during charging as this electric capacity 4.
If the 4th switch element 24 is deactivated, that is, disconnects, this electric capacity 4 is pre-charged by this resistance 23, thus preventing
Such as due to the infringement to this electric capacity 4 that current surge causes.
If capacitance voltage reaches predetermined value or battery voltage value it is preferable that enabling or closing the 4th switch element
24 it means that electric current can flow to this electric capacity 4 via corresponding chopper 7 in the clear, thus can improve capacitance voltage,
So that capacitance voltage eventually exceeds cell voltage.It is similarly to the operational mode of boost converter or booster transformer.
This charge controlling element 20 connects chopper the 7, the 3rd switch 22 and the 4th switch to this two-way charge controller 5
24, and preferably control the charging of this battery 6, thus this battery will not for example be overcharged or not yet charge in this battery
Charge when full and interrupt in advance.
Additionally, this charge controlling element 20 can also control the charging of this intermediate circuit electric capacity 4, thus in charging process
In the case of not damaging this electric capacity, in charging process, capacitance voltage is promoted to and exceedes battery voltage value.
Therefore, charge or charged the battery using external power source to use batteries to electric capacity, this charge controlling element
20 need to drive the chopper 7 of this two-way charge controller according to the function of each of which.
Should be noted it is preferable that an ingredient of the 3rd switch element 22 two-way charge controller 5 that is this, and
It is not an ingredient of this battery 6.
