[0002] With the increase of electrical appliances installed on electrical equipment, the requirements for batteries of electrical equipment are getting higher and higher. Loading multiple batteries at the same time has become a demand and has been widely used.

[0003] Other batteries installed at the same time may be divided into different functions. For example, for a vehicle, the additional battery is used to power the vehicle air conditioner (also known as the parking air conditioner). In this way, the vehicle air conditioner can be used even when the vehicle is stopped and started. This scenario is particularly suitable for trucks and other vehicles, because truck drivers often need to park directly in the vehicle to rest. At this time, it is better to use a dedicated vehicle battery to power the vehicle air conditioner.

[0004] When multiple different batteries are loaded on an electrical device (such as a vehicle), the battery itself will encounter problems that need to be solved, and the design of the entire power supply system of the electrical device also becomes a requirement. If the design is not appropriate, a series of problems will arise. Summary of the invention

[0007] As a further improvement, the switching device is a contactor, the contactor coil is connected between the first positive electrode and the negative electrode, and the contactor main contact is connected between the first positive electrode and the second positive electrode.

[0008] As a further improvement, it also includes a time relay electrically connected between the first positive electrode and the negative electrode, and the time relay is a power-on delay type.

[0009] As a further improvement, the time relay coil is connected in series between the first positive electrode and the negative electrode, and the time relay normally open contact is connected in series between the first positive electrode and the contactor.

[0010] In order to solve the above problems, the present invention also provides an electrical device equipped with the battery as described above.

[0011] To solve the above problems, the present invention also provides a circuit system of an electrical equipment, including a generator, a motor, a load and an original battery, and also includes a battery as described above, wherein the generator is connected to both ends of the original battery, the motor and the generator are connected to the original battery in parallel, the positive electrode of the original battery is connected to the first positive electrode, the negative electrode of the original battery is connected to the negative electrode, and the load is connected between the second positive electrode and the negative electrode.

[0012] As a further improvement, the first positive electrode is connected to an on-shift switch of an electrical device.

[0013] As a further improvement, an electrical equipment accessory power-on switch is connected in series between the electrical equipment power-on switch and the positive electrode of the original battery.

[0014] As a further improvement, an electrical equipment starting switch is connected in series between the electrical equipment on-shift switch and the motor.

[0015] In order to solve the above problems, the present invention also provides another electrical device, including the electrical device circuit system as described above.

[0016] Beneficial effects of the present invention:

[0017] 1. The battery provided by the present invention adopts a double positive electrode structure, and a switch device is connected between the double positive electrodes, which not only realizes the independent power supply of the battery to the external electrical appliance, but also greatly improves the practicality of the electrical equipment; the battery can also be connected to the circuit system of the electrical equipment, so that the generator of the electrical equipment can charge the battery;

[0018] 2. The electric equipment circuit system provided by the present invention is provided with an original battery and a battery at the same time, and uses the switch device of the battery and the electric equipment starting system (key switch system) of the electric equipment to form an ingenious circuit structure, thereby ensuring that when the generator of the electric equipment stops working, the original battery and the battery will not be charged mutually; in addition, when the power of the original battery is insufficient, the motor cannot be started at the first start, that is, the electric equipment cannot be started; however, in the electric equipment circuit system provided by the present invention, the battery can be connected in time, so that the battery can power the motor, and the electric equipment can be started;

[0019] 3. In the further improved circuit system of the electric equipment of the present invention, a power-on delay type time relay is connected between the first positive electrode and the negative electrode, and the delay prevents the battery and the original battery from charging each other during the startup process;

[0020] 4. Connect the battery to the circuit system of the electrical equipment, and control the main circuit line through the different gear switches of the electrical equipment starting system. This not only makes the electronic control logic clear, but also facilitates troubleshooting when faults occur later. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The electrical equipment in this embodiment may be a machine in a factory, a vehicle, or a transportation vehicle such as a ship or an airplane. The following embodiments are described with a vehicle as a specific electrical equipment.

[0027] When a vehicle is loaded with multiple different batteries, since each battery needs to be charged by the vehicle generator during operation, the positive pole of each battery is usually connected to the positive end of the vehicle generator, and the negative pole of each battery is usually connected to the negative end of the vehicle generator. However, this structure results in that when the vehicle generator stops running, the positive poles of each battery are connected to each other, and the negative poles are also connected to each other. At this time, the battery with a higher voltage will charge the battery with a lower voltage. This is the mutual charging phenomenon. The mutual charging phenomenon will occur repeatedly between different batteries, and the charging direction may be constantly changed. It will cause the internal storage of each battery to be continuously consumed in vain, reduce the voltage of each battery, and accelerate the loss of the battery. Therefore, avoiding mutual charging of batteries is very critical for vehicles with multiple batteries installed.

[0028] To this end, the present invention provides a new battery based on the design of the battery itself to overcome the above-mentioned battery mutual charging problem, and also provides a corresponding vehicle circuit system and a corresponding vehicle.

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings.

[0030] Reference Figure 1 As shown, a battery E1 provided by an embodiment of the present invention is shown.

[0031] The battery E1 includes a first positive electrode 1 and a negative electrode 3 , and also includes a second positive electrode 2 , and a switching device (not distinguished by label) electrically connected between the first positive electrode 1 and the second positive electrode 2 .

[0032] Reference Figure 1 As shown, in this embodiment, the switch device is a contactor KM. The coil of the contactor KM is connected between the first positive electrode 1 and the negative electrode 3 , and the main contact of the contactor KM is connected between the first positive electrode 1 and the second positive electrode 2 .

[0033] This embodiment uses the contactor KM, which takes advantage of the performance of the contactor KM that can pass a relatively large current. In other embodiments, the contactor KM can also be replaced by other devices, such as a relay.

[0034] Another embodiment of the present invention provides another battery E1. Figure 2 As shown, the battery E1 in this embodiment, in addition to having the corresponding structure of the above-mentioned embodiment, also includes a time relay KT electrically connected between the first positive electrode 1 and the negative electrode 3, and the time relay KT is a power-on delay type. The coil of the time relay KT is connected in series between the first positive electrode 1 and the negative electrode 3, and the normally open contact of the time relay KT is connected in series between the first positive electrode 1 and the contactor KM. The battery is powered by a battery pack U.

[0035] Another embodiment of the present invention provides another battery, referring to Figure 3 As shown, the battery comprises: a box body 5; a first positive electrode 1, a second positive electrode 2, a negative electrode 3 and a battery switch 4 arranged on the box body 5. For other structures in the battery of this embodiment, reference may be made to the corresponding contents of the above-mentioned embodiments.

[0036] Although not shown in the figure, the batteries provided in the above embodiments of the present invention can also be directly installed in a vehicle as an original vehicle battery to form a vehicle equipped with the battery. In such a vehicle, the batteries provided in the above embodiments can be used as vehicle batteries to power various electrical devices on the vehicle, and because the battery has two positive electrodes (a first positive electrode and a second positive electrode).

[0037] The present invention also provides a vehicle circuit system, please refer to Figure 1 .

[0038] The vehicle circuit system includes a generator M1, a motor M2, a load M3 and a vehicle battery E2, and also includes the aforementioned battery E1, the generator M1 is connected to both ends of the vehicle battery E2, the motor M2 and the generator M1 are connected to the vehicle battery E2 in parallel, the positive electrode of the vehicle battery E2 is connected to the first positive electrode 1, the negative electrode of the vehicle 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.

[0039] Reference Figure 1 As shown, the first positive electrode 1 is connected to the vehicle on-shift switch ON of the vehicle starting system.

[0040] Reference Figure 1 As shown, the vehicle accessory power-on switch ACC of the vehicle starting system is connected in series between the vehicle on-speed switch ON of the vehicle starting system and the positive electrode of the vehicle battery E2.

[0041] Reference Figure 1 As shown, a vehicle start gear switch START is connected in series between the vehicle on gear switch ON and the motor M2.

[0042] The working principle of the vehicle circuit system provided in this embodiment is:

[0043] When the vehicle is turned off and the vehicle key stops at the LOCK position, the internal battery pack U supplies power to the load M3, that is, the battery E1 supplies power to the load M3 through the second positive electrode 2 and the negative electrode 3; since the load M3 is usually a vehicle electrical device such as a vehicle refrigerator or a vehicle air conditioner with a switch, the working state of the load M3 is not affected by whether the vehicle is started; and at this time, the switch device (that is, the contactor KM) remains disconnected, that is, the first positive electrode 1 is disconnected from the positive electrode of the internal battery pack U, so the positive electrodes of the vehicle battery E2 and the battery E1 are disconnected from each other, thereby preventing the vehicle battery E2 and the battery E1 from being charged mutually;

[0044] When the vehicle key stops at the ACC gear (vehicle accessory power-on gear) position, the vehicle accessory power-on gear switch ACC of the vehicle starting system is closed, and at this time, the vehicle battery E2 can provide power for vehicle starting;

[0045] When the vehicle key is turned from the ON position (vehicle connection position) to the START position (vehicle start position), the vehicle accessory power-on position switch ACC is closed, the vehicle connection position switch ON is closed, and the vehicle start position switch START is closed, the motor M2 is connected to the vehicle battery E2, and the motor M2 is started until the engine ignites successfully and the generator M1 starts to operate; in this process, it should be noted that when the vehicle key is turned from the ACC position to the START position, it must pass through the ON position in the middle, and when the vehicle key is turned to the ON position, the vehicle circuit system of this embodiment can use the power supply of the vehicle battery E2 to energize the contactor KM coil inside the battery E1, so that the main contact of the contactor KM can be closed, and then the first positive electrode 1 is connected to the second positive electrode 2. At this time, the generator M1 is ready to charge the battery E1. When the generator M1 starts to operate later, the battery E1 can continue to receive the charging effect;

[0046] Release the vehicle key, and the vehicle key returns from the START position (vehicle start position) to the ON position (vehicle connection position). At this time, the vehicle accessory power-on position switch ACC is closed, the vehicle connection position switch ON is closed, and the vehicle start position switch START is disconnected. The coil of the contactor KM remains energized, so the main contact of the contactor KM remains closed, and the generator M1 charges the vehicle battery E2 and the battery E1.

[0047] Reference Figure 1 As shown, when the vehicle battery E2 is low on power and the motor M2 cannot be started, since it has been rotated to the ON position during the starting process, the vehicle accessory power-on position switch ACC is closed, the vehicle connection position switch ON is closed, the contactor KM coil is energized, and the main contact of the contactor KM is closed. During the ignition process, the battery E1 can also provide power at the same time. Therefore, the vehicle start position switch START is closed, and the battery E1 and the vehicle battery E2 are connected in parallel with the motor M2 to ensure that the motor M2 starts, thereby ensuring that the generator M1 starts to operate.

[0048] The present invention also provides another vehicle circuit system, please refer to Figure 2 .

[0049] Most of the structure of the vehicle circuit system is similar to Figure 1 The structures of the vehicle circuit systems shown are the same, the only difference is that Figure 2 Compared with the battery E1 Figure 1 The battery E1 is provided with a time relay KT. The connection structure between the time relay KT and other structures of the battery E1 can refer to the corresponding contents of the above-mentioned embodiment.

[0050] Due to the addition of the time relay KT, the working principle of this embodiment is similar to Figure 1 The operating principle of the vehicle circuit system shown is different in that:

[0051] When the vehicle key is turned from the ON position to the START position, the vehicle accessory power switch ACC is closed, the vehicle connection switch ON is closed, and the vehicle start switch START is closed, and the motor M2 is connected to the vehicle battery E2; at this time, due to the action of the time relay KT, the motor M2 and the battery E1 are not yet connected (because the first positive electrode 1 and the second positive electrode 2 of the battery E1 are not yet connected); at this time, the vehicle circuit system of this embodiment only relies on the vehicle battery E2 to ignite the motor M2 until the engine ignites successfully and the generator M1 starts to run; in this way, it is possible to well avoid the battery E1 from participating in the engine ignition process, so that the power of the battery E1 is more dedicated to the electrical equipment on the vehicle, ensuring that the vehicle battery E2 and the battery E1 can better perform their respective functions;

[0052] However, when the vehicle battery E2 is insufficient to ignite the engine successfully, the vehicle circuit system provided in this embodiment can still use battery E1 to assist in the ignition and start of the vehicle; this is because the delay time of the time relay KT is usually only set to a few seconds to tens of seconds. After the delay, the battery E1 and the motor M2 will be connected. At this time, the battery E1 can still be used to ignite the motor M2; that is, in the event that the vehicle cannot be started normally due to insufficient power in the vehicle battery E2 itself, the vehicle circuit system provided in this embodiment can use battery E1 to start after a period of time. Therefore, in this case, the vehicle can still be successfully started in subsequent ignition operations (such as the second or third time, etc.). The above process can be referred to. Figure 2 As shown, when the vehicle battery E2 is low on power, the vehicle battery E2 itself cannot start the motor M2. Since the vehicle starting system has reached the ON position at this time (the vehicle starting system can be a key rotation start system or a push button start system), the vehicle accessory power-on position switch ACC is closed and the vehicle connection position switch ON is closed. When the time relay KT coil is energized and reaches the set time, the normally open contact of the time relay KT is closed, the contactor KM coil is energized, and the main contact of the contactor KM is closed. At this time, if the ignition is turned on again, the vehicle starting position switch START is closed, the battery E1 is connected to the motor M2, the motor M2 is started, and the generator M1 starts to run.

[0053] The working principle and working process of this embodiment can refer to the corresponding contents of the above-mentioned embodiments.

[0054] Although not shown in the figure, the present invention Figure 1 and Figure 2The vehicle circuit system shown can be set on a corresponding vehicle, and is particularly suitable for large vehicles such as trucks. In this case, the vehicle is a vehicle with a corresponding vehicle circuit system, and the battery E1 on the vehicle can be used for vehicle user equipment such as air conditioners, refrigerators or induction cookers in the truck cab.

[0055] The beneficial effects of the present invention are:

[0056] 1. The battery provided by the present invention adopts a double positive electrode structure, and a switch device is connected between the double positive electrodes, which not only realizes the independent power supply of the battery to the external electrical appliance, but also greatly improves the practicality of the electrical equipment; the battery can also be connected to the circuit system of the electrical equipment, so that the generator of the electrical equipment can charge the battery;

[0057] 2. The electric equipment circuit system provided by the present invention is provided with an original battery and a battery at the same time, and uses the switch device of the battery and the electric equipment starting system (key switch system) of the electric equipment to form an ingenious circuit structure, thereby ensuring that when the generator of the electric equipment stops working, the original battery and the battery will not be charged mutually; in addition, when the power of the original battery is insufficient, the motor cannot be started at the first start, that is, the electric equipment cannot be started; however, in the electric equipment circuit system provided by the present invention, the battery can be connected in time, so that the battery can power the motor, and the electric equipment can be started;

[0058] 3. In the further improved circuit system of the electric equipment of the present invention, a power-on delay type time relay is connected between the first positive electrode and the negative electrode, and the delay prevents the battery and the original battery from charging each other during the startup process;

[0059] 4. Connect the battery to the circuit system of the electrical equipment, and control the main circuit line through the different gear switches of the electrical equipment starting system. This not only makes the electronic control logic clear, but also facilitates troubleshooting when faults occur later.

[0060] The same or similar parts between the above-mentioned embodiments in this specification can be referenced to each other, and each implementation method focuses on the differences from other implementation methods, but it is not limited to the differences that cannot be replaced or superimposed on each other.

[0061] The above embodiments are only used to explain the technical solutions of the present invention rather than to limit them. Those skilled in the art should understand that any modification and equivalent substitution that does not depart from the spirit and scope of the present invention should fall within the protection scope of the claims of the present invention.
