Description

Technical Field

[0001] The present invention belongs to the technical field of charging isolation, and particularly relates to an isolation controller for intelligent dual batteries based on a motor vehicle. Background Art

[0002] The working principle of the currently commonly used dual-battery charging isolator is as follows: when the electrical equipment of the main battery is started, such as when the car engine is started, when the voltage of the main battery reaches a certain voltage value, generally between 27VNUM (NUM refers to the number of batteries), the dual-battery charging isolator is engaged, and the common positive terminals of the main battery and the auxiliary battery are connected in series to realize simultaneous charging of the main battery and the auxiliary battery by the car or ship generator. When the voltage of the main battery is lower than a certain voltage value, generally 26.7VNUM or below, the dual-battery charging isolator will disconnect, and the main battery and the auxiliary battery are isolated.

[0003] The existing device lacks remote monitoring and control. Users cannot obtain the battery status and cannot remotely control the isolator. Moreover, in extremely low-temperature situations, the main battery and the secondary battery of the existing device cannot supply power to the starter simultaneously, resulting in insufficient power supply.

[0004] Therefore, an isolation controller for intelligent dual batteries based on a motor vehicle is designed to solve the above problems. Summary of the Invention

[0005] To solve the problems raised in the above background art, the present invention provides an isolation controller for intelligent dual batteries based on a motor vehicle. When the device is in use, the two thick wires of the two-hole aviation socket of the isolator body are respectively connected to the positive poles of the main and auxiliary batteries. During use, the internal power monitor can monitor the battery capacity in real time. When the battery power is insufficient, the actuator inside the insulating cover is automatically started through the control end. Its execution rotating shaft drives the drive shaft to rotate, the drive shaft drives the outer bracket to rotate, and then drives the rotating seat and the outer battery clamping plate to rotate, realizing the switching between the main battery and the auxiliary battery, so as to ensure sufficient power for the starter.

[0006] During the power supply process, the operating electric telescopic rod can push the insulating rod, and the insulating rod smoothly pushes the contact electric sheet along the outside of the telescopic thin copper rod. Through the preset stroke of the displacement sensor, when the set value is reached, the contact electric sheet can be connected to the main battery or the auxiliary battery at the top, and the battery at the bottom of the bracket is switched to the standby state. On the other hand, the device can precisely control the execution structure, making the originally vertically arranged main battery and auxiliary battery in a horizontal state, so that in a low-temperature environment, the two groups of battery clamping plates of the device can complete the dual power supply of the main and auxiliary batteries, thus ensuring sufficient power supply for the starter.

[0007] To ensure the stability of the battery connection, the small motor inside the rotating seat can be started automatically. Its execution rotating shaft drives the connecting shaft to rotate. Since the two sets of locking gears on the outside are engaged, the locking gear at the top can drive the guide shaft and the fine grinding block on the outside to rotate synchronously, thus achieving the effect of reducing the rotation speed of the fine grinding block. Since the limiting spring on the outside is always in a stretched state, during the rotation of the fine grinding block, the polishing sheet inside the battery clamp can always adhere to the surface of the fine grinding block and complete the synchronous opening and closing effect in the rotating state, ensuring that the battery clamp can firmly hold the main and auxiliary batteries of different sizes, thereby effectively preventing missed connections.

[0008] To achieve the above object, the present invention provides the following technical solutions: An intelligent dual-battery isolation controller based on a motor vehicle, including a flexible isolation controller.

[0015] Preferably, for an isolation controller for an intelligent dual - battery based on a motor vehicle according to the present invention, electric telescopic rods and insulating rods are further provided on both sides of the telescopic thin copper rod. The output end of the electric telescopic rod is fixedly connected to the inside of the insulating rod, and the outside of the insulating rod is fixedly connected to the surface of the contact - type electric sheet.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, the two thick wires of the two - hole aviation socket of the isolator body are respectively connected to the positive electrodes of the main and auxiliary batteries. During use, the internal power monitor can monitor the battery capacity in real - time. When the battery power is insufficient, the actuator inside the insulating cover is automatically started through the control terminal. Its execution rotating shaft drives the driving shaft to rotate, the driving shaft drives the outer bracket to rotate, and then drives the rotating seat and the outer battery clamping plate to rotate, realizing the switching between the main battery and the auxiliary battery, so as to ensure sufficient power for the starter.

[0018] 2. During the power supply process, the operating electric telescopic rod can push the insulating rod, and the insulating rod smoothly pushes the contact - type electric sheet along the outside of the telescopic thin copper rod.

[0019] 3. In the present invention, to ensure the stability of the battery connection, the small motor inside the rotating seat can be automatically started.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figure 1 and Figure 7 shown:

[0032] An isolation controller for intelligent dual batteries based on a motor vehicle. The working principle of the commonly used dual-battery charging isolator is that when the voltage of the main battery is lower than a certain voltage value, generally 26.7VNUM or below, the dual-battery charging isolator will disconnect, and the main battery and the auxiliary battery are isolated. The existing device lacks remote monitoring and control, and users cannot obtain the battery status or remotely control the isolator. Moreover, in extremely low-temperature situations, the main battery and the secondary battery of the existing device cannot supply power to the starter simultaneously, resulting in insufficient power supply. On this basis, a flexible isolation controller 1 is added.

[0033] An isolation controller for intelligent dual batteries based on a motor vehicle can also perform intelligent control according to the states of the main and auxiliary batteries and the engine, so as to use the two batteries for simultaneous charging and separate use. The main functions are as follows:

[0034] 1. Isolation: Under normal circumstances, the connection between the main and auxiliary batteries is cut off to ensure that there is no internal consumption between the two batteries and extend the battery life.

[0035] 2. Protection: Automatically connect the main and auxiliary batteries during startup, and the vehicle can still be started when the main battery has insufficient power.

[0036] 3. Control: Automatically detect the voltage and implement the protection function. After startup, when the voltage of the auxiliary battery is insufficient, charge and maintain it.

[0037] 4. Power borrowing: When the main battery is out of power, press the emergency switch to borrow power from the auxiliary battery to start the engine.

[0038] 5. Auxiliary startup: In extremely low-temperature situations, the main battery and the auxiliary battery can supply power to the starter simultaneously. After normal startup, the isolation controller can automatically separate the main and auxiliary batteries.

[0039] As Figure 1 、 Figure 3 and Figure 7 shown:

[0040] In an optional embodiment: The flexible isolation controller 1 includes an isolator body 11, a power monitor 12, a contact electric sheet 13, a telescopic thin copper rod 14, and a battery clamp 15. The telescopic thin copper rod 14 is fixedly connected to the inside of the isolator body 11. The power monitor 12 is electrically connected to the bottom of the contact electric sheet 13. The contact electric sheet 13 is welded and fixed to the outside of the telescopic thin copper rod 14. The battery clamp 15 is movably connected to the outside of the contact electric sheet 13. Electric telescopic rods 9 and insulating rods 10 are also provided on both sides of the telescopic thin copper rod 14. The output end of the electric telescopic rod 9 is fixedly connected to the inside of the insulating rod 10, and the outside of the insulating rod 10 is fixedly connected to the surface of the contact electric sheet 13.

[0041] In this embodiment: The two thick wires of the two-hole aviation socket 20 of the isolator body 11 are respectively connected to the positive electrodes of the main and auxiliary batteries. During use, the internal power monitor 12 can monitor the battery capacity in real time. When the battery power is insufficient, the actuator 22 inside the insulating cover 21 is automatically started through the control terminal. The actuator 22 includes, but is not limited to, a stepping motor. An actuating rotating shaft is provided at its output end, and the actuating rotating shaft is fixedly connected to the driving shaft 23 through a coupling. The actuating rotating shaft drives the driving shaft 23 to rotate, the driving shaft 23 drives the outer bracket 24 to rotate, and further drives the rotating seat 25 and the outer battery clamping plate 15 to rotate, realizing the switching between the main battery and the auxiliary battery, so as to ensure sufficient power for the starter.

[0042] It should be noted that: When the main battery is damaged or out of power, press the emergency switch, and the isolation controller will automatically connect the main battery and the auxiliary battery in parallel, and the vehicle can be started by borrowing the power of the auxiliary battery.

[0043] A control method for an isolation controller for an intelligent dual-battery based on a motor vehicle, which is applicable to the above-mentioned isolation controller for an intelligent dual-battery based on a motor vehicle, specifically includes the following steps:

[0044] Step 1: First, when the engine is started, if the voltage of the main battery is lower than 26.7V, at this time, the isolation controller will automatically separate the main and auxiliary batteries, and the vehicle engine will first charge the main battery;

[0045] Step 2: When the engine is started, if the isolation controller detects that the voltage of the main battery is higher than 26.7V, the isolation controller will be started after a delay of 10S. At this time, the engine will charge the main and auxiliary batteries in parallel at the same time;

[0046] Step 3: When the isolation controller detects that the engine voltage is between 26.7V and 29.8V, it will maintain the state of charging the main and auxiliary batteries at the same time;

[0047] Step 4: If it is detected that the engine voltage exceeds 32V + 0.6V, the isolation controller will automatically separate the main and auxiliary batteries;

[0048] Step 5: When the isolation controller detects that the voltage of the main battery is lower than 25.8V, after a delay of 30S, the isolation controller will automatically separate the main and auxiliary batteries, and this state is after starting the engine and then shutting down;

[0049] Step 6: When not charging or discharging, and the voltage of the main battery is lower than 25.8V, the isolation controller will automatically separate the main and auxiliary batteries;

[0050] Step 7: When discharging when the engine is not working and the voltage of the main battery is lower than 25.8V, the auxiliary battery discharges, and the isolation controller will automatically separate the main and auxiliary batteries;

[0051] Step 8: When the emergency switch is pressed, the isolation controller will activate the following functions:

[0052] ⅰ) When the main battery is damaged or discharged, pressing the emergency switch will cause the isolation controller to automatically parallel the main battery and the auxiliary battery, allowing the vehicle to be started using the power of the auxiliary battery.

[0053] ⅱ) When the emergency switch returns to its initial state, the isolation controller will automatically separate the main battery and the auxiliary battery.

[0054] ⅲ) If the emergency switch is not turned off after 45 seconds of being pressed, the isolation controller will automatically separate the main battery and the auxiliary battery. At this time, if the emergency switch is not turned off, the main and auxiliary batteries will always be in an isolated state.

[0055] Step 9: When the ignition lock start signal is valid, the isolation controller will activate the auxiliary function:

[0056] First, the START signal of the isolation controller is connected to the ignition lock start signal. When the ignition lock start signal is valid, the isolation controller automatically parallels the main battery and the auxiliary battery.

[0057] Step 10: At the same time, when the main battery loses power, the isolation controller will perform the following processing:

[0058] ⅰ) When the main battery loses power during operation, the isolation controller will automatically separate the main battery and the auxiliary battery.

[0059] ⅱ) When the main battery returns to normal from a power loss, the isolation controller will automatically control the states of the main battery and the auxiliary battery according to Steps 1 to 9 above.

[0060] Step 11: When the auxiliary battery is severely discharged, the isolation controller will control the activation of the pulse charging function:

[0061] ⅰ) When the engine is running and the voltage of the auxiliary battery is still below 26.7V after it is connected, the isolation controller controls the auxiliary battery to be in a short-term intermittent charging mode.

[0062] ⅱ) When the engine is running and the voltage of the auxiliary battery is still below 25.7V after it is connected, the isolation controller controls the auxiliary battery to be in a long-term intermittent charging mode.

[0063] Furthermore:

[0064] As Figure 2 、 Figure 3 and Figure 4 shown:

[0065] In an alternative embodiment: The adjusting part 2 includes an insulating cover 21, an actuator 22, a drive shaft 23, a bracket 24, a rotating seat 25 and a limiting spring 26. The insulating cover 21 is fixedly installed on one side of the inner cavity of the isolator body 11. The actuator 22 is fixedly connected to the inner side of the insulating cover 21. One end of the drive shaft 23 is fixedly connected to the output end of the actuator 22 through a coupling. The surface of the bracket 24 is fixedly connected to the outer side of the drive shaft 23. The rotating seat 25 is fixedly connected to the outer side of the bracket 24. Both ends of the limiting spring 26 are fixedly connected to the surfaces of the battery clamping plate 15 and the rotating seat 25 respectively. A displacement sensor 8 is also arranged on the inner side of the isolator body 11.

[0066] In this embodiment: During the power supply process, the operating electric telescopic rod 9 can push the insulating rod 10. The insulating rod 10 steadily pushes the contact electric sheet 13 along the outer side of the telescopic thin copper rod 14. Through the preset stroke of the displacement sensor 8, when the set value is reached, the contact electric sheet 13 can be connected to the main battery or the secondary battery at the top, and the battery located at the bottom of the bracket 24 is switched to the standby state. On the other hand, the device can control the execution shaft torque of the actuator 22, so that the originally vertically arranged main battery and secondary battery are in a horizontal state, so that in a low-temperature environment, the two battery clamping plates 15 of the device can complete the dual power supply of the main and secondary batteries, thereby ensuring sufficient power supply for the starter.

[0067] It should be noted that: After the engine stalls and the engine voltage is detected to be lower than 26V, the isolation controller will automatically separate the main and secondary batteries.

[0068] Combined with the above content:

[0069] As Figure 5 and Figure 6 shown:

[0070] In an alternative embodiment: A small motor 3, a connecting shaft 4 and a guide shaft 5 are also arranged inside the rotating seat 25. The output end of the small motor 3 is fixedly connected to one end of the connecting shaft 4 through a coupling. The guide shaft 5 is rotatably connected inside the rotating seat 25. A locking gear 30 is also meshed and connected to the relative sides of the connecting shaft 4 and the guide shaft 5. A fine grinding block 6 is also fixedly connected to the outer side of the guide shaft 5. The outer wall of the fine grinding block 6 is slidably connected to the inner side of the battery clamping plate 15. A polishing sheet 7 is also arranged on the inner side of the battery clamping plate 15.

[0071] In this embodiment: To ensure the stability of battery connection, the small motor 3 inside the rotating seat 25 can be started automatically. Its driving shaft drives the connecting shaft 4 to rotate. Since the two locking gears 30 on the outside are meshed with each other, the locking gear 30 at the top can drive the guide shaft 5 and the fine grinding block 6 on the outside to rotate synchronously, thus achieving the decelerating rotation effect of the fine grinding block 6. Since the limiting spring 26 on the outside is always in a stretched state, during the rotation of the fine grinding block 6, the polishing sheet 7 inside the battery clamp 15 can always adhere to the surface of the fine grinding block 6 and complete the synchronous opening and closing effect in the rotating state, ensuring that the battery clamp 15 can firmly hold the main and auxiliary batteries of different sizes, thereby effectively preventing missed connections.

[0072] It should be noted that during charging, when the isolation controller detects that the voltage is higher than 27V and delays for 10S to start the isolation controller, at this time, the engine charges the main and auxiliary batteries in parallel simultaneously.

[0073] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
