AC inverter circuit 232 includes transformer 280 and integrated circuit 282, and they are jointly in exchange output 210 Modified AC sine wave is produced between neutral terminal N and line terminal L.AC inverter circuit 232 produces voltage about 115V, the alternating current that rated power is 65W.Inverter circuit 232 is received by battery protecting circuit 234 and comes from internal cell 207 electric energy.By pressing AC power button 224 to send a signal to inverter circuit, to enable AC inverter circuit 232, and by pressing AC power button 224 for the second time to send a signal to inverter circuit, to disable AC inverter Circuit 232.These signals are provided by microcontroller 240 (in schematic diagram 23 show), microcontroller response AC power button The button of 224 (being shown in schematic diagram 24) promotes.

Battery protecting circuit 234 integrates the charging of internal cell 207 by charging circuit 256, and charging circuit 256 is contained in (shown on USB circuit plate 252 in schematic diagram 22).During charging, battery protecting circuit 234, which provides, overcharges protection and list Body equilibrium function.Overcharge and be protected from filling any single battery monomer into the monomer voltage higher than 4.2V.Monomer equilibrium function carries For for being balanced by monomer voltage balance in 50mV and by charging current in 300mA.Similarly, internally battery 207 Electric discharge during, battery protecting circuit 234 provide monomer under-voltage protection.

Mainboard 230 is connected with AC Power supply socket 210, its also accommodate AC overcurrent protection circuit 244 and exchange overvoltage/ Under-voltage protecting circuit 246.If the output current for being output to AC Power supply socket 210 exceedes predetermined threshold value, AC overcurrent is protected Protection circuit 244 can provide a signal to microcontroller 240.Signal from current foldback circuit 244 can cause microcontroller 240 to be sent out The number of delivering letters is to inverter circuit 232 is exchanged, to disable AC inverter circuit.Similarly, if neutral terminal N and line terminal When output voltage between L exceedes default high low range, then signal can be provided to micro-control by exchanging overvoltage/under-voltage protecting circuit 246 Device 240 processed.Signal from exchange overvoltage/under-voltage protecting circuit 246 can cause microcontroller 240 to send a signal to ac converter Device circuit 232.

Therefore, when pressing AC power button 224 to open AC Power supply socket 210, microcontroller 240 can verify friendship Flow protection circuit 240,242.Microcontroller 240 can also verify battery protecting circuit 234, and will prevent from being less than in cell voltage Operation in the case of 10V.During these verifications (needing about 4 seconds), microcontroller 240 can cause the effective LED of AC power 272 (behind AC power button 224, and being shown in schematic diagram 24) send flashed green.If detect under-voltage bar Part-for example, total cell voltage will be then output to below about the voltage on any monomer of 10V or battery below about 2.8V- Before the electric energy of AC Power supply socket 210 is automatically cut off, microcontroller 240 can cause the effective LED 272 of AC power continuously to send out Go out flashed green one minute.On the other hand, if harmonics circuit 240,242 and internal battery voltage verification meet the requirements When, then microcontroller 240 can cause the effective LED 272 of AC power to send stable green glow.

In addition, during electric energy is provided from AC Power supply socket 210, the continuous monitoring power output of microcontroller 240.If Detect excessively stream (overpower) condition-for example, traction power can will be output to alternating current more than about 80W- so microcontrollers 240 The electrical discontinuity of supply socket 210, and AC power mistake LED 274 can be caused to send red flashing light, until pressing friendship again Power knob 224 is flowed to close AC socket 210.On the other hand, if microcontroller 240 detects the situation of underpower (traction power is below about 1W), then after one minute, microcontroller will be switched off the power supply of AC Power supply socket 210.

Also with reference to Figure 21, mainboard 230 also accommodates bridging start-up circuit 236, and it inserts internal cell 207 with priming supply The operability electrical connection of seat 209.Bridging start-up circuit 236 includes the safety relay 238 that is controlled by microcontroller 240, with order to There is provided or disconnect the electric energy that priming supply socket 209 is output to from internal cell 207.Especially, it is output to from microcontroller 240 First signal of safety relay 238 can cause safety relay to open, to prevent internal cell 207 and priming supply socket 209 electrical connection.On the other hand, the secondary signal for safety relay 238 being output to from microcontroller 240 can cause safety relay Device is closed, to allow the electrical connection of internal cell 207 and priming supply socket 209.

According to the signal from multiple protection circuits, microcontroller 240 transmits a signal to safety relay 238, Duo Gebao Protection circuit includes electricity folder checking circuit 248, reverse-current protection circuit 250 and Opposite direction connection detection circuit 266 and (illustrated Shown in Figure 23).If the signal that microcontroller 240 receives from all safety circuits all meets the requirements, then it will be peace All relay 238 is powered, to allow electric current to flow through priming supply socket 209 from internal cell 207.

According to the voltage detected at priming supply socket, whether electricity folder checking circuit 248 verifies charging cable crocodile clip It is connected on on-vehicle battery.More specifically, priming supply socket 209 comprises more than positive pole and negative power supply socket 286,287, also Including positive pole and negative pole sensing socket 288,289.At priming supply socket 209, socket 288,289 and outlet are sensed 286th, 287 electric insulation.Charging cable and its crocodile clip have special design (following reference chart 25 is described further), so as to energy It is enough by by charging cable crocodile clip be connected on the on-vehicle battery with least some remaining capacities come to sensing socket 288, 289 are powered.When using correct polarity, (current potential of positive pole sensing socket 288 senses socket 289- for example, extremely higher than negative pole Few high about 2.8V) when to be powered to sensing socket 288,289, they drive the optoisolator 290 in electricity folder checking circuits 248, Satisfactory electricity folder checking signal is provided to microcontroller 240 so as to press from both sides detection circuit from electricity.As described above, electricity folder checking signal It is the one of which signal needed for the closed safe relay 238 of microcontroller 240.Therefore, electricity folder checking circuit 248 is provided and prevented The spark of closed safe relay 238 is protected before electricity folder is connected into battery to be charged.Although shown as electricity folder verification letter Number it is low signal, but alternatively, when crocodile clip is attached on the terminal of on-vehicle battery, electricity folder checking circuit 248 can It is configured to produce high RST.

Reverse-current protection circuit 250 verifies whether on-vehicle battery is attempted by priming supply socket 209 to internal cell 207 are charged.If reverse-current protection circuit 250 detects greater than about 10A reverse current, it can send shutoff signal To microcontroller 240.Opposite direction connection detects circuit 266 according to the voltage detected at priming supply socket 209, verification charging electricity Whether cable crocodile clip is reversed at on-vehicle battery.

Microcontroller 240 also performs a variety of other security functions.These functions include on-vehicle battery overvoltage verification and it is vehicle-mounted Battery undervoltage/short-circuit calibration.Verified according to on-vehicle battery overvoltage, if the voltage at priming supply socket 209 is more than about 13.2V, then microcontroller 240 can stay open safety relay 238.According to on-vehicle battery it is under-voltage/short-circuit calibration, such as fruit dot Voltage at thermoelectricity supply socket 209 is less than 2.5V, then microcontroller 240 can stay open safety relay 238.Therefore, owe Pressure verification also provides short-circuit protection, is in contact to prevent positive pole and negative pole cable electricity folder.

, can be right by charging circuit 256 it illustrates the USB circuit plate 252 of portable charger 200 with reference to figure 22 Internal cell 207 is charged, and charging circuit 256 electrically connects with the operability of DC supply input connector 214.Charging circuit 256 receive pulse width modulating signal from microcontroller 240, and provide charging voltage to battery protecting circuit 234.

USB circuit plate 252 also accommodates USB power source circuit 254, and it is electrically connected with the operability of USB power source socket 208.USB electricity Source circuit 254 receives 5V DC current by battery protecting circuit 234 (as shown in figure 21) from internal cell 207.When passing through When pressing USB power source button 222 to enable USB power source circuit 254, it provides 5V/2.4A DC current to each USB power source Socket 208.USB power source circuit 254 provides following characteristics at D+, D- line of USB power source socket 208：Distributor (divider) 1 DCP, for providing every line 2.7V；BC1.2 DCP, for the short circuit between D+, D- line；China Telecom standard YD/T 1591-2009 short-circuit modes (Shorted Mode), for the short circuit between D+, D- line；And on D+ and D- lines it is 1.2V.

When enabling USB power source circuit 254, the effective LED 264 of USB power source behind USB power source button 222 sends stabilization Green glow.Similarly, when enabling USB power source circuit 254, microcontroller 240, which monitors, turns off detection circuit 292 for one minute, and one Minute shut-off detection circuit 292 sends low current signal to microcontroller 240, passes through being less than for USB power source socket 208 to respond 30mA traction current.After the low current signal of one minute is received from one minute shut-off detection circuit 292, microcontroller 240 USB power source circuit 254 can be cut off, 5V DC currents are disconnected from USB power source socket 208.Extraly, microcontroller 240 is logical Cross the voltage that battery protecting circuit 234 monitors internal cell 207.If each monomer voltage of internal cell less than 2.8V or Total internal battery voltage is less than 10V, then microcontroller 240 can cut off USB power source circuit 254.

Microcontroller 240 responds starts bridging initiating sequence from off-state by starting switch 200 is bridged next time. Bridge in initiating sequence, microcontroller 240 causes multiple events to occur in a specific sequence.First, in microcontroller 240 verifies The electricity of portion's battery 207.If internal cell 207 has the electricity (greater than about 11V output) more than 50%, microcontroller 240 may proceed to carry out bridging initiating sequence.Otherwise, bridging initiating sequence is exited.

Then, bridging starts the flashed green that effective LED 258 sends about 4 seconds, while the verification of microcontroller 240 comes from three The safety signal of individual bridging starting protection circuit.If Opposite direction connection detection circuit 266 indicates that charging cable electricity folder is attached to mistake Battery terminal, then bridging, which starts wrong LED 260, can send red flashing light by mistake, until pressing bridging start button 267 again Come the bridging start-up circuit 236 for closing of setting out.On the other hand, if any other safety condition is not met for, bridge Starting effective LED 258 can continue to send the flashed green up to 1 minute, while microcontroller 240 continues monitoring and met the requirements Safety check.After monitoring in one minute, microcontroller 240 can cut off bridging initiating sequence.

After safety check is satisfactorily completed, the closed safe relay 238 of microcontroller 240, with to priming supply socket 209 It is powered, and bridges and start the green glow that effective LED 258 sends stabilization.Microcontroller 240 then starts the countdown of five minutes. During the countdown of five minutes, bridging can be up to attempted three times and starts the connected vehicle of electricity folder.In order to detect successfully or lose The bridging lost starts vehicle and attempted, the voltage at the monitors ignition power outlet 209 of microcontroller 240.Start for bridging every time Vehicle is attempted, and microcontroller 240 will allow starting current (up to 500A) to flow through priming supply socket 209, for up to four seconds. If vehicle battery voltage is continued above 13.2V (this can cause the reverse current from on-vehicle battery to internal cell), detect Start to successful bridging.If after the starting current of four seconds, on-vehicle battery voltage is not above 13.2V, then detects The bridging of failure starts.At the end of countdown in 5 minutes or after successful bridging startup or in the bridging to fail three times After startup or electricity folder and vehicle or priming supply socket 209 disconnect whenever, microcontroller 240 can open safety Relay 238, internal cell 207 and priming supply socket 209 are disconnected.

During countdown in five minutes, the also continuous monitoring traction power (power draw) of microcontroller 240.Charger 200 are configurable for providing the load current (radio, compressor of air conditioner etc.) of similar 100A fragmentary auxiliary, until Bridging is attempted for the first time starts vehicle.If however, microcontroller 240 detect traction current continue to exceed 30A time it is big In 30 seconds, then microcontroller can cause safety relay 238 to open, and cause bridging to start wrong LED 260 and send quick flashing Feux rouges and cause USB power source LED to send the blue light of quick flashing.

Figure 23 shows microcontroller circuit plate 242, and it accommodates microcontroller 240 and LED floodlight 212, floodlight Button 218 and bridging start Opposite direction connection detection circuit 266.By a floodlight button 218, pass through microcontroller 240 Gate transistor 284 enables LED floodlight 212.Floodlight button 218 is pressed for the second time, passes through microcontroller 240 and gates crystalline substance Body pipe 284 disables LED floodlight 212.The operation that bridging starts Opposite direction connection detection circuit 266 is described above.

With reference to figure 24, an AC power button 224 can be pressed so that microcontroller 240 enables AC inverter circuit 232, and disable AC inverter circuit 232 by for the second time.When AC inverter circuit 232 is effective, microcontroller 240 cause the effective LED 272 of AC power to send stable green glow.If alternating current circuit verification is undesirable, as described above, Then microcontroller 240 causes AC power mistake LED 274 to send red flashing light.
