The central-processor 25 compares the current, voltage, and voltage noises, and when the transient voltage and current drops and the rapid rise and voltage generate noise and fast recovery, both conditions are met simultaneously. The central processing unit 25 outputs a signal to the output control circuit 27, and the output control circuit 27 continues to connect the vehicle. The battery 1 is powered by the vehicle main battery 1 to the external electrical device 3; 'the central processing unit 25 starts to send a signal to cause the timer 28 Start timing the main battery. The timer 28 is set according to the time when the battery is normally powered. The setting method is as follows:

Tsetm=(Cpm - Ck)/ Σ Ai In the embodiment of the vehicle battery power management method of the present invention, the total amperage of the external electrical appliance Σ Ai is 9.6A, the normal battery available power is 85% Cpm, and the second minimum is started again. The required power Ck is 1.4 Ah, and the time Tsetm set by the main battery power supply timer is 2 hours and 45 minutes. # During the power supply of the main battery 1, the current voltage detecting circuit 24 will continuously sample, send current and voltage values to the central processing unit 25 and the voltage protection circuit 26, and the voltage protection circuit 26 receives the current sent by the current voltage detecting circuit and The voltage value, if the abnormal voltage of the battery is found to be too high, higher than the main battery 1 pole • the high voltage VHHm ' sends a signal to the output control circuit π to cut off the output of the main battery 1 to protect the battery from continuing to supply power to cause permanent damage to the battery or Danger occurs, and the external electrical appliance 3 can be protected from over-electricity damage; if the abnormal voltage of the battery is found to be too low, lower than VLLm, a signal is sent to the output control circuit 27 to cut off the output of the main battery 1 to protect the battery from continuing to supply power. ^ The battery is permanently damaged or dangerous, and the external electrical device 3 can be protected from the low 1288516. This is one of the features of the present invention. In the present embodiment, the VHHra fork is about 16·〇ν, and the VLLm is set to about 9.6V. Before the timer 28 reaches the Tsetm, according to the set time, the central processing unit 25 sends a signal, and the buzzer 292 emits the sound of the second y. 'Warning to turn off the main battery i to turn on the backup battery 21; At the same time, a signal is output, and the display 291 indicates that the main battery 1 of the vehicle is about to arrive, and the main battery 1 is turned off to turn on the backup battery 21. When 2=timed_ arrives at Tsetm, the central processing unit 25 sends out the "credit battery 21 and cuts off the main battery two-three frequency sound, the center; f, gives the display, to remind the owner to keep ίί ' ίϋ' Ϊ: during the power supply, The current-voltage detecting circuit 24 will guarantee whether the ===== processor-to-tank reaches Tsetm, and the center=2 has 5^ to CHm, no matter when the 292 is issued, the phase-in-one disk is smeared.

Tsetb=(Cpb - 〇〇/ Σ Ai - In the embodiment of the vehicle battery power management method of the present invention, the total ampere of the external device is 9·6 Α, the normal battery available power is 8〇% Cpb, and the second time is 20 times again. The required power is L4Ah, and the backup battery timing is set to 1 hour. During the power supply of the backup battery 21, the voltage current detecting circuit % will continuously sample, and send the current A and the voltage V value to the central processing unit 25 And the voltage protection circuit 26, the voltage protection circuit 26 receives the current and voltage value sent by the voltage and current detection circuit 24. If the abnormal voltage of the backup battery 21 is too high, and is higher than the limit high voltage vHHb of the backup battery 21, a signal is sent to the output. The control circuit 27 cuts off the output of the backup battery 21 to protect the battery from continuing to cause permanent damage or danger to the backup battery 21, and protects the external electrical device 1288516 1288516

The earth is protected from overvoltage damage; the central processor 3 sends a signal to the buzzer 292 to emit a fourth frequency sound, and a battery abnormality sound is emitted; the central processing unit 3 sends a signal to display the injury battery on the display 291. 21 anomaly to warn the owner. If the battery abnormal voltage is found to be too low, &amp; the standby battery 21 limits the low voltage VLLb, a signal is sent to the output control circuit 27 to cut off the backup battery 21 output to protect the backup battery 21 from being continued: the battery causes permanent damage to the battery or Danger occurs, and the external electrical appliance can be protected from low voltage damage; the central processor 3 sends a signal to the bee 292 to emit a fourth frequency sound, and a warning sound of the battery abnormality is sent; the central processor 25 sends out a The signal indicates that the backup battery 21 is abnormal on the display 291 to warn the owner. This is yet another feature of the invention. In the present embodiment, VHHb is set to be about 16.0V and VLLb is set to be about 9.6V. Before the central battery 25 backup battery timing reaches the time, according to the set time, the central processing unit 25 sends a signal, and the buzzer 292 emits a second frequency sound, reminding the backup battery 21 to set the power ^到达 When it arrives, the backup battery 21 will be turned off; the central processing unit 25 sends a code: The display 291 displays the amount of power set by the backup battery, ie, the standby power (10). When the backup battery 21 reaches the heart 2, the =25 sends a signal, the drive output control circuit "provided; = the processor 25 sends the - signal to make the beep first to use the residual power for restarting. This is Further, one step, and during the backup battery 21 power supply, the voltage electricity production circuit 24 will continue to sample, send current and voltage values to the central processing AtM, t^21CLb 犄, no: 8 defensive 到达 no arrived at the camel ratio The central processor throws a second frequency sound to the buzzer 292 to warn the owner that the standby power is about to be exhausted, and the central processor 25 sends out _ signals, which are displayed on the display 12 1288516; The power is about to arrive. 'The standby control circuit will be turned off. After a specified time, the output signal will be sent to the central processing unit. The output control circuit 27 will cut off the output of the backup battery 21, and the central processing signal will beep. The device 292 emits a fourth frequency sound, 291', and the backup battery 21 has stopped the power supply signal to the display to be dangerous, and the battery is prevented from continuing to supply power, causing permanent damage to the battery or the occurrence of the remaining part of the battery. The vehicle needs to be restarted again. This situation has been seen before the old car is turned off, the backup battery 21 has not been fully charged or the battery characteristics. Can not save enough normal power. This is another test of the invention to supply power to the vehicle external electrical device 3 When the 'voltage and current detection start and stop】 between the detection of battery voltage and loop current, the vehicle moves. When the central production 3, according to the sampling time to detect whether the vehicle is restarted from the fish fast 25 received the vehicle start stop detection circuit 23 detect Measured to receive the re-start feature of the wish cell electrode, and the characteristics of the central processor 25 charging η 2 ί 24 detected that the charger 4 started to the vehicle main battery = 丨 broken car light has been activated and the charger 4 is the main The circuit 27 connects the main battery 1 and the backup battery 21 to start the S power supply; the further processing of the central processing unit 2.
