Description

Technical Field

[0001] The utility model relates to a lead-acid battery liquid level detection system, in particular to a remote wireless maintenance system for vehicle-mounted batteries. Background Art

[0002] Liquid electrolyte batteries, such as common lead-acid batteries, provide electrical energy through electrochemical reactions. The electrochemical reaction involves the reaction of an acid, such as sulfuric acid, with the battery electrodes to generate an electrical potential. Due to the reliability and low cost of lead-acid batteries, lead-acid batteries are one of the main power sources for self-powered vehicles (including, for example, forklifts and reach trucks), backup power, and other applications. However, when lead-acid batteries are charged and discharged, as well as when heated, the electrolyte inside the battery will heat up and accelerate the evaporation of water vapor. The water vapor easily overflows from the assembly gap of the battery, causing the electrolyte to suffer water loss.

[0003] Insufficient electrolyte in lead-acid batteries can lead to a series of risks and problems. First of all, the electrolyte plays an important role in conducting electricity and participating in chemical reactions in lead-acid batteries. When the electrolyte is insufficient, the conductivity inside the battery will be affected, resulting in a decrease in the battery's output power. This will directly affect the normal operation of the battery and make it unable to meet the expected power demand.

[0004] Secondly, insufficient electrolyte will accelerate the aging and damage of the battery. Lack of electrolyte will cause the plates in the battery to be exposed to the air, which will cause oxidation and sulfidation of the plates. Long-term operation without electrolyte will cause serious sulfidation of the plates, eventually causing the battery to lose its charging and discharging capabilities, and even cause the battery to break. In addition, insufficient electrolyte will increase the internal resistance of the battery, reducing the battery's charging acceptance and cycle life.

[0005] Furthermore, insufficient electrolyte will also affect the safety performance of the battery. The battery generates heat during the charging and discharging process, and insufficient electrolyte will cause the heat dissipation performance inside the battery to decrease, making the battery more prone to overheating. Long-term overheating may cause the chemical substances inside the battery to be unstable, and even cause safety risks such as thermal runaway or explosion of the battery.

[0006] Therefore, in order to ensure the normal operation and safety performance of lead-acid batteries, the electrolyte level of the battery must be checked regularly and the appropriate amount of electrolyte must be added in time. At the same time, attention should also be paid to the charging and maintenance of the battery to avoid long-term storage and over-discharge in order to extend the battery life and improve its performance stability.

[0007] To this end, the existing patent has a sensor installed inside the battery for detecting the electrolyte level, which can achieve the effect of automatically detecting the liquid level and display the liquid level information through the vehicle-mounted sound and light alarm device. However, due to the high corrosion and high temperature difference environment inside the battery, the reliability of the sensor is difficult to guarantee, and there are problems such as high sensor cost and sensor standby power consumption. In addition, the vehicle-mounted sound and light alarm device can only be detected when someone is there. For vehicles that have been unmanned for a long time, the existing alarm method cannot produce a reliable effect. Summary of the invention

[0008] The utility model provides a remote wireless maintenance system for vehicle-mounted batteries, which solves the problems of unreliable alarm mode and power consumption in standby mode in the prior art.

[0009] The above technical problems of the utility model are mainly solved by the following technical solutions: a remote wireless maintenance system for a vehicle-mounted battery, characterized in that it includes a vehicle-mounted battery, a liquid level detection component arranged in the battery, a microprocessor, a wireless transmission module electrically connected to the microprocessor, a cloud server and a user terminal with a wireless signal receiving function; the liquid level detection component includes a mounting seat that passes through and is fixed on the upper cover of the vehicle-mounted battery, a hollow probe that passes through the mounting seat and vertically extends into the interior of the vehicle-mounted battery, a detection switch arranged at the bottom of the inner cavity of the hollow probe, and a detection switch sleeved on the hollow probe. The outer magnetic buoyancy ring and the hollow probe tube cannot be made of ferromagnetic materials. The bottom end of the hollow probe tube is set close to the bottom plate of the vehicle battery. The magnetic buoyancy ring includes an annular buoyancy body and an annular permanent magnet buried therein. The inner diameter of the annular buoyancy body is slightly larger than the outer diameter of the hollow probe tube. The detection switch includes a fixed positive electrode sheet and a negative electrode sheet that naturally droops due to gravity. The negative electrode sheet is generally close to the side wall of the hollow probe tube. The negative electrode sheet is provided with ferromagnetic material, and a gap is formed between the positive electrode sheet and the negative electrode sheet. The positive electrode sheet and the negative electrode sheet are electrically connected with wires. The two wires pass through the mounting seat and are electrically connected to the pins of the microprocessor.

[0010] The microprocessor in this system is electrically connected to the vehicle battery. The microprocessor is divided into a standby state and a wake-up state. The power consumption in the standby state is extremely low. When the vehicle is in a stopped state, the microprocessor will automatically wake up or standby periodically according to the system preset. In the awake state, the microprocessor will energize the detection switch in the liquid level detection component, and the magnetic buoyancy ring will float on the surface of the electrolyte. When the electrolyte in the vehicle battery is at a normal liquid level, the magnetic field of the magnetic buoyancy ring will not cause the negative electrode to flip too much. The negative electrode is naturally vertical due to gravity. At this time, the negative electrode is not in contact with the positive electrode, so the detection switch is in an open circuit state and no power is consumed as a whole. When the electrolyte level is too low, the distance between the magnetic buoyancy ring and the negative electrode becomes shorter. At this time, the magnetic field will cause the negative electrode to deflect outward, causing the negative electrode to approach the positive electrode. Once the two are in contact, the detection switch is in a pass state, and the microprocessor can detect this electrical signal and control the wireless transmission module to send a wireless signal to the cloud server. The communication mode of the wireless transmission module can be 2.4G, 4G, etc. The cloud server will back up the information corresponding to the vehicle information, and use wireless signals to send the information of insufficient electrolyte to the user terminal.

[0011] Furthermore, it also includes a vehicle-mounted prompting device electrically connected to the microprocessor. The utility model can also be configured to automatically perform a liquid level detection each time the vehicle is started, and control the vehicle-mounted prompting device to give a corresponding prompt according to the detection result, so as to facilitate the driver's observation.

[0012] Therefore, compared with the prior art, the utility model has the following characteristics: 1. Changes in the liquid level will drive the magnetic buoyancy ring to rise and fall, and a too low liquid level will cause the magnetic buoyancy ring to be too close to the negative electrode, causing the negative electrode to be attracted by the magnetic field and deflected, thereby realizing the conduction of the detection switch. In this way, the utility model will send the information to the user terminal wirelessly, so that the alarm information can be discovered by the driver in time; 2. When the liquid level is within a safe range, the detection switch is in a normally open state and does not consume electricity. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The microprocessor in this system is electrically connected to the vehicle battery. The microprocessor is divided into a standby state and a wake-up state. The power consumption in the standby state is extremely low. When the vehicle is in a stopped state, the microprocessor will automatically wake up or standby periodically according to the system preset. In the awake state, the microprocessor will energize the detection switch in the liquid level detection component, and the magnetic buoyancy ring will float on the surface of the electrolyte. When the electrolyte in the vehicle battery is at a normal liquid level, the magnetic field of the magnetic buoyancy ring will not cause the negative electrode to flip too much. The negative electrode is naturally vertical due to gravity. At this time, the negative electrode is not in contact with the positive electrode, so the detection switch is in an open circuit state and no power is consumed as a whole. When the electrolyte level is too low, the distance between the magnetic buoyancy ring and the negative electrode becomes shorter. At this time, the magnetic field will cause the negative electrode to deflect outward, causing the negative electrode to approach the positive electrode. Once the two are in contact, the detection switch is in a closed state, and the microprocessor can detect this electrical signal and control the wireless transmission module to send a wireless signal to the cloud server. The communication mode of the wireless transmission module is 4G. The cloud server will back up the information corresponding to the vehicle information, and use wireless signals to send the information of insufficient electrolyte to the user terminal.

[0023] See Figure 3 and Figure 4 The mounting seat is composed of a swivel body 211 and a stop ring 212. The swivel body is screwed together with the upper cover of the battery. A groove 110 for accommodating the stop ring is provided on the inner surface of the upper cover of the battery. A sealing ring 120 is provided in the groove to closely contact the stop ring. A sealant 130 is filled between the stop ring and the outer contour of the groove. This can greatly improve the sealing effect of the mounting seat and reduce the leakage of water vapor from the matching part of the mounting seat.
