Above-mentioned power circuit is connect to provide operating voltage with single-chip microcontroller U1, single-chip microcontroller U1 respectively with low current charge circuit
10, the control terminal of high-current charging circuit 20 is connected to control its charging work or disconnection, low current charge circuit 10, high current
The output end of charging circuit 20 by the bridge rectifier 30 rectify after export electric current to battery charging port (VO+,
VO-)；
Above-mentioned low current charge circuit 10, high-current charging circuit 20 all using mechanical relay and triode (K1, Q1,
K2, Q2) it is used as switching device, first is shorted input port (9 feet, 8 of resistance R42, the second short circuit resistance R43 and single-chip microcontroller U1
Foot) connection and combine and be shorted by the two whether determine that charging voltage specification gives single-chip microcontroller U1, specification figure is as shown in Figure 3.
As the further perfect of the technical program, one to fill Multifunctional electric vehicle charger further include overcharge protection circuit 40,
The overcharge protection circuit 40 is serially connected between bridge rectifier 30 and the charging port of battery, and overcharge protection circuit 40 uses machine
Tool relay K3 with triode Q4 as switching device and its control terminal is connect with the single-chip microcontroller U1, since K2, K1 circuit are false
When cannot such as turn off on time or out of control, voltage can be more than after upper limit voltage 15.5V five seconds, and single-chip microcontroller can turn off by force K3,
Bad effect is not filled to play battery.
As the further improvement of the technical program, one to fill Multifunctional electric vehicle charger further include battery voltage detection circuit
50, V-BATTERY battery voltage detection circuits: being made of D10, R38, D14, R39, C35, the battery voltage detection circuit 50
It is connect with the single-chip microcontroller U1 to ensure that single-chip microcontroller U1 is worked normally again after charging port access battery.In addition, being additionally provided with
Vdd voltage detection circuit: it is made of R7, D13, R6, C4.
As the further improvement of the technical program, one to fill Multifunctional electric vehicle charger further include connecting with single-chip microcontroller U1
Temperature protection control circuit, is made of R7/R4, R5, C5, and when temperature, which is higher than+80, to be spent, single-chip microcontroller stops working, green at this time
LED, red LED flash alarm simultaneously.
As the further improvement of the technical program, one to fill Multifunctional electric vehicle charger further include connecting with single-chip microcontroller U1
LED indicating circuit, by green LED, red LED composition, which is used to indicate the working condition of charger.
This charger is that one kind to switch working principle reaches charging purpose, that is to say, that single group battery is in low-voltage
Circuit is connected when 13.5V, is disconnected in high voltage 15.5V, is judged whether battery fills by the charging time of several sections of open and close
It is full.
Battery of electric vehicle is currently used 36V, 48V, 64V, and tetra- kinds of voltages of 72V, 36V is by the battery strings of three 12V
Join, 48V is by four, and 60V is by five, and for 72V by 6 battery compositions, the lower voltage limit of single group battery is set as small by we
It is connected when 13.5V, disconnection when upper limit voltage is set greater than 15.5V, if constantly open voltage will continue to rise damage battery.
The charging principle and process of the technical program are as follows: if first connect 220V power supply, charger be it is idle, at this time
Red LED flashing alarm, VO+, VO- do not have voltage output, K1, K2, and K3 is in an off state, and are primarily due to security consideration, because
It is charger voltage considerably beyond human body 36V safe voltage.VO must first connect battery, then connect 220V power supply, and charger is
It can work normally, at this time U1,10 feet obtain a positive high-voltage level, and U1 starts to work, and 5 feet export high level, Q4, K3
Conducting, 6,7 feet, 3 seconds output high level of delay, Q1, K1, Q2, K2 conducting, electric current pass through C14, R16, R17, C11, R13, R12
Charge and discharge are changed into DC voltage after the bridge rectifier of D3, D4, D5, D6 composition and charge the battery, i.e. starting high current is filled
Electricity.Wherein, work as VO+, VO- output access battery pack positive and negative anodes, voltage will lower, and (battery pack is equivalent to voltage-stablizer or load
Effect), as charging progresses, battery voltage is gradually increasing, and capacitance-resistance voltage reduction circuit only serves the effect of current limliting.
It is large current charge first by taking single group battery as an example, when single group cell voltage reaches 15.5V, the delay of 6,7 feet
Low level, Q1, K1 are exported, Q2, K2 are disconnected, it completes to charge for the first time, although single group cell voltage reaches 15.5V at this time, by
There is the effect of " inertia " in then large current charge, lead to actual voltage virtual height and underfill, after tested virtual voltage
Reach the 60% of voltage rating, therefore, Q1, K1, voltage can decline after Q2, K2 are disconnected；
When voltage drops to 13.5V, 7 feet export again, and Q1, K1 conducting, this electric current only pass through C11, and R13, R12 carry out small
Electric current charging, i.e. floating charging, also referred to as trickle charge；Capacity is bigger, and the required charging time is longer, otherwise shorter, so anti-
Low current switch charging is carried out again, and when being less than or equal to 180 seconds in the charging time from 13.5V to 15.5V, green LED is red
LED is lighted simultaneously, indicate at this time battery have been filled with 70% electricity, when charging between be less than or equal to 60 seconds when, indicate at this time
Battery has been filled with 90% electricity, when charging between be less than or equal to 20 seconds when, indicate at this time battery have been filled with 100% electricity
Amount, green LED are gone out, and K3, K1 are disconnected, charging complete.
The utility model charger by resistance R43, R42 short circuit over the ground, can disconnect on same circuit board,
Realize the input signal of different combinations to single-chip microcontroller, combining form be respectively (R42 connection, R43 connection), (R42 connection,
R43 is disconnected), (R42 disconnect, R43 connection), (R42 is disconnected, R43 is disconnected), four kinds combine respectively represent 36V, 48V, 64V,
The input signal of four kinds of specification charging voltages such as 72V, then when single-chip microcontroller receives the input signal and identifies that user wants that
Kind specification charging voltage may be selected the corresponding charge mode prestored and implement charging to battery pack.
The foregoing is merely the preferred embodiments of the utility model, the utility model is not limited to above-mentioned embodiment party
