However, this structure causes the positive electrodes of the respective batteries to be connected to each other and the negative electrodes of the respective batteries to be connected to each other after the vehicle generator stops operating, and at this time, the battery having a higher voltage charges the battery having a lower voltage, which is a mutual charging phenomenon. The mutual charging phenomenon is repeated among different batteries, and the charging direction can be continuously changed, which causes the electric quantity stored in each battery to be continuously consumed, reduces the voltage of each battery and accelerates the loss of the batteries. Therefore, it is critical to avoid the mutual charging of the batteries for the vehicle to install a plurality of batteries.

The embodiment of the utility model provides a vehicle circuit system still provides, please refer to fig. 1.

The vehicle circuit system comprises a generator M1, a motor M2, a load M3, a vehicle-mounted battery E2 and the vehicle-mounted battery E1, wherein the generator M1 is connected to two ends of the vehicle-mounted battery E2, the motor M2 and the generator M1 are connected to the vehicle-mounted battery E2 in parallel, the positive electrode of the vehicle-mounted battery E2 is connected to the first positive electrode 1, the negative electrode of the vehicle-mounted battery E2 is connected to the negative electrode 3, and the load M3 is connected between the second positive electrode 2 and the negative electrode 3.

Referring to fig. 1, the first positive electrode 1 is connected to a vehicle ON switch ON of a vehicle starting system.

Referring to fig. 1, a vehicle accessory ON-range switch ACC of the vehicle starting system is connected in series between the vehicle ON-range switch ON of the vehicle starting system and the positive electrode of the vehicle-mounted battery E2.

Referring to fig. 1, a vehicle START switch START is connected in series between the vehicle ON switch ON and the motor M2.

The working principle of the vehicle circuit system provided by the embodiment is as follows:

when the vehicle is turned off and the vehicle key is stopped in the LOCK range (vehicle LOCK range) position, the load M3 is powered by the internal battery pack U, i.e., the load M3 is powered by the vehicle battery E1 through the second positive electrode 2 and the negative electrode 3; since the load M3 is usually a vehicle electric device such as a vehicle-mounted refrigerator or a vehicle-mounted air conditioner having a switch, the operating state of the load M3 is not affected by whether the vehicle is started or not; and, at this time, the switching device (i.e., contactor KM) is kept open, i.e., the first positive electrode 1 is disconnected from the positive electrode of the internal battery pack U, and therefore, the positive electrodes between the vehicle-mounted battery E2 and the vehicle battery E1 are disconnected from each other, preventing the mutual charging phenomenon of the vehicle-mounted battery E2 and the vehicle battery E1;

when the vehicle key is stopped in the ACC range (vehicle accessory power range) position, the vehicle accessory power range switch ACC of the vehicle starting system is closed, at which time the on-vehicle battery E2 can supply power for vehicle starting;

when a vehicle key is turned from an ON gear (vehicle ON gear) to a START gear (vehicle START gear) position, a vehicle accessory ON gear switch ACC is closed, a vehicle ON gear switch ON is closed, a vehicle START gear switch START is closed, a motor M2 is connected with an ON-vehicle battery E2, a motor M2 is started until engine ignition is successful, and a generator M1 STARTs to operate; in this process, it should be noted that when the vehicle key is turned from the ACC gear to the START gear, the middle of the vehicle key inevitably passes through the ON gear, and when the vehicle key is turned to the ON gear, the vehicle circuit system of this embodiment may utilize the power supply function of the vehicle-mounted battery E2 to energize the coil of the contactor KM inside the vehicle battery E1, so that the main contact of the contactor KM may be closed, and further the first positive electrode 1 is connected to the second positive electrode 2, which is to make preparation for the generator M1 to charge the vehicle battery E1, and when the subsequent generator M1 STARTs to operate, the vehicle battery E1 may continuously receive the charging function;

when the vehicle key is released, the vehicle key returns to an ON gear (vehicle ON gear) from a START gear (vehicle starting gear), a vehicle accessory electrifying gear switch ACC is closed, a vehicle ON gear switch ON is closed, a vehicle starting gear switch START is opened, a coil of a contactor KM is electrified, a main contact of the contactor KM is closed, and a generator M1 charges a vehicle-mounted battery E2 and a vehicle battery E1;

referring to fig. 1, when the electric quantity of the vehicle-mounted battery E2 is insufficient, the motor M2 cannot be started, and since the vehicle-mounted battery E2 is rotated to the ON position during the starting process, the vehicle accessory ON position switch ACC is closed, the vehicle ON position switch ON is closed, the coil of the contactor KM is energized, and the main contact of the contactor KM is closed, the vehicle battery E1 can also provide power simultaneously during the ignition process, so the vehicle starting position switch START is closed, the vehicle battery E1 and the vehicle-mounted battery E2 are connected in parallel to be connected with the motor M2, the motor M2 is ensured to be started, and the generator M1 is ensured to START to operate.

The embodiment of the utility model provides a still provide another kind of vehicle circuit system, please refer to fig. 2.

Most of the structure of the vehicle circuit system is the same as that of the vehicle circuit system shown in fig. 1, except that a time relay KT is added to the vehicle battery E1 of fig. 2 as compared to the vehicle battery E1 of fig. 1. The connection structure of the time relay KT to other structures of the vehicle battery E1 can be referred to the corresponding contents of the foregoing embodiments.

Due to the addition of the time relay KT, the operating principle of the present embodiment differs from the operating principle of the vehicle circuit system shown in fig. 1 in that:

when the vehicle key is turned from the ON position to the START position, the vehicle accessory ON switch ACC is closed, the vehicle ON switch ON is closed, the vehicle START switch START is closed, and the motor M2 is turned ON with the vehicle-mounted battery E2; at this time, the motor M2 and the vehicle battery E1 have not been turned on yet (because the connection between the first positive electrode 1 and the second positive electrode 2 of the vehicle battery E1 has not been made yet) due to the action of the time relay KT; at this time, the vehicle circuit system of the embodiment only depends on the vehicle-mounted battery E2 to ignite and start the motor M2, until the engine is ignited successfully, and the generator M1 starts to operate; therefore, the vehicle battery E1 can be well prevented from participating in the process of engine ignition, the electric quantity of the vehicle battery E1 is more specially used for electric equipment on the vehicle, and the vehicle-mounted battery E2 and the vehicle battery E1 are ensured to better perform respective functions;

however, when the vehicle battery E2 is not sufficiently charged to successfully ignite the engine, the vehicle circuit system provided in the embodiment can still assist the ignition start of the vehicle by using the vehicle battery E1; this is because the delay action time of the time relay KT is usually set to be only between a few seconds and a few tens of seconds, after the delay, the vehicle battery E1 is connected with the motor M2, and at this time, the motor M2 can still be ignited by the vehicle battery E1; that is, in the event that the vehicle cannot be normally started due to the insufficient electric quantity of the vehicle-mounted battery E2, the present embodiment provides that the vehicle electrical system can be started using the vehicle battery E1 after a certain period of time has elapsed, and therefore, in this case, the vehicle can still be successfully started in a subsequent ignition operation (e.g., a second or third time, etc.). As shown in fig. 2, when the electric quantity of the ON-board battery E2 is insufficient, the ON-board battery E2 itself cannot START the motor M2, and since the vehicle starting system has reached the ON position (the vehicle starting system may be a key-operated starting system or a key-operated starting system), the vehicle accessory ON position switch ACC is closed, the vehicle ON position switch ON is closed, when the time relay KT coil is energized for a set time, the normally open contact of the time relay KT is closed, the contactor KM coil is energized, the main contact of the contactor KM is closed, and if ignition is performed again, the vehicle ON position switch START is closed, the vehicle battery E1 is connected with the motor M2, the motor M2 is started, and the generator M1 STARTs to operate.

The working principle, working process and the like of the present embodiment can refer to the corresponding contents of the foregoing embodiments.

Although not shown, the vehicle circuit system shown in fig. 1 and 2 according to the present invention may be installed in a corresponding vehicle, and is particularly suitable for use in a large-sized vehicle such as a truck, and in this case, the vehicle is a vehicle having the corresponding vehicle circuit system, and the vehicle battery E1 on the vehicle may be used in a vehicle user device such as an air conditioner, a refrigerator, or an induction cooker in a cab of the truck.
