Description

Technical Field

[0001] This invention relates to the field of vehicle battery charging technology, and in particular to a method, apparatus, equipment and medium for charging vehicle batteries. Background Technology

[0002] With the increasing popularity of new energy heavy-duty trucks, their low-voltage electrical systems (such as body controllers, gateways, instruments, lights, etc.) still require a 24V battery for power. After a long period of inactivity, vehicles often fail to start due to a depleted battery ("grounded"), severely impacting uptime and user experience.

[0003] Currently, the mainstream solution on the market is to recharge the battery when it is low on power. Its basic working principle is: when the battery's power level is detected to be below a certain set threshold, and the vehicle's main battery has sufficient power, a DC-DC converter will convert the high-voltage DC output from the main battery into low-voltage DC to charge the battery.

[0004] However, the aforementioned existing technology has the following drawbacks:

[0005] 1. Single parameter dependence: Existing solutions usually rely solely on the battery's charge level, neglecting the crucial parameter of the battery's health status.

[0006] 2. Inability to cope with battery sulfation: When a battery's plates become sulfated (its health deteriorates) due to prolonged shallow charging and discharging or being left to deplete, its internal resistance increases, and its ability to accept charging decreases significantly. At this time, traditional constant voltage or constant current charging modes are extremely inefficient, and a large amount of electrical energy will be converted into heat energy and consumed, or even fail to effectively increase the battery's capacity.

[0007] 3. Serious energy waste: In the above-mentioned sulfation state, in order to recharge a battery that cannot be charged, the vehicle's power battery will be kept awake for a long time, resulting in a large amount of power battery being wasted, which contradicts the original intention of energy saving in new energy vehicles.

[0008] 4. Reduced battery life: Traditional forced charging cannot reverse the sulfation phenomenon of batteries. On the contrary, it may accelerate the aging of batteries, leading to premature battery failure, increasing the user's operating costs and wasting resources. Summary of the Invention

[0009] This invention provides a method, apparatus, device, and medium for charging vehicle batteries, in order to solve the problems of existing vehicle battery charging methods that fail to consider the impact of battery health status on charging, resulting in inability to cope with battery sulfation, serious energy waste, and shortened battery life.

[0015] The vehicle power battery is controlled to charge the vehicle battery according to the charging method. When the charging method is the first charging method, the vehicle power battery is controlled to charge the vehicle battery. When the charging method is the second charging method, the pulse activator is first controlled to output pulse current to the vehicle battery to perform desulfurization treatment on the vehicle battery, and then the vehicle power battery is controlled to charge the vehicle battery.

[0018] When the first real-time battery state of charge SOC1 satisfies: SOC1 < SOC1_high, the first real-time battery health state SOH1 satisfies: SOH1 < SOH1_healthy, and the second real-time battery state of charge SOC2 satisfies: SOC2 > SOC2_work, the charging method is the second charging method.

[0019] Optionally, controlling the vehicle's power battery to charge the vehicle's storage battery includes:

[0020] The vehicle power battery is controlled to charge the vehicle battery until the first real-time battery health state SOC1 satisfies: SOC1≥SOC1_high, where SOC1_high represents the battery state of charge depletion threshold of the vehicle battery.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0045] Figure 1This is a flowchart illustrating a vehicle battery charging method according to an embodiment of the present invention. The vehicle battery charging method described in this embodiment is applicable to situations requiring battery charging. This method can be executed by a vehicle battery charging device, which can be implemented in software and / or hardware and specifically configured within a vehicle battery charging equipment. (Reference) Figure 1 Methods for charging vehicle batteries include:

[0046] S110. Obtain the first real-time battery state of charge and the first real-time battery health state of the vehicle's storage battery, as well as the second real-time battery state of charge of the vehicle's power battery.

[0047] For example, the vehicle battery in this embodiment of the invention can be a low-voltage lead-acid battery. When the vehicle triggers a power-off lock or a gateway timed wake-up event, the vehicle battery charging device in this embodiment of the invention can obtain the first real-time battery state of charge and the first real-time battery health status of the vehicle battery, as well as the second real-time battery state of charge of the vehicle power battery, through a battery sensor (a built-in sensor integrated in the battery management system (BMS) or a separately installed smart sensor).

[0048] It should be noted that the vehicle gateway timed wake-up event refers to the mechanism by which the gateway automatically wakes up at preset time intervals after the vehicle is turned off and put into sleep mode, relying on modules such as the internal real-time clock (RTC); the real-time battery state of charge (SOC) refers to the percentage of the battery's current remaining usable power relative to its rated capacity, which reflects the current level of electrical energy that the battery can output; the real-time battery state of health (SOH) refers to the rate of degradation of the battery's current actual performance (the core of which is the actual capacity) relative to its initial performance at the factory, which reflects the battery's health level after long-term use.

[0049] S120: Control the vehicle power battery to charge the vehicle storage battery based on the first real-time battery state of charge, the first real-time battery health state, and the second real-time battery state of charge.

[0050] Understandably, the first real-time state of charge of the vehicle battery can help determine whether the vehicle battery needs to be recharged, the first real-time health state of the vehicle battery can help determine whether the vehicle battery is suitable for recharging, and the second real-time state of charge of the vehicle power battery can help determine whether the vehicle power battery has enough charge to charge the vehicle battery. Therefore, to ensure efficient charging of the vehicle battery, the vehicle battery recharging device in this embodiment of the invention can be configured to control the vehicle power battery to charge the vehicle battery based on the first real-time state of charge and the first real-time health state of the vehicle battery and the second real-time state of charge of the vehicle power battery.

[0051] The technical solution of this invention addresses the problem of existing vehicle battery charging methods failing to consider the impact of battery health on charging, which leads to issues such as battery sulfation, severe energy waste, and shortened battery life due to the lack of consideration for battery health during charging.

[0052] Figure 2 A flowchart of another vehicle battery charging method provided in an embodiment of the present invention. Figure 2 The illustrated embodiment provides a detailed explanation of how to control the vehicle's power battery to charge the vehicle's storage battery based on a first real-time battery state of charge, a first real-time battery health state, and a second real-time battery state of charge. (Refer to...) Figure 2 Methods for charging vehicle batteries include:

[0053] S210. Obtain the first real-time battery state of charge and the first real-time battery health state of the vehicle's storage battery, as well as the second real-time battery state of charge of the vehicle's power battery.

[0054] S220. Determine the battery charging method based on the first real-time battery state of charge, the first real-time battery health state, and the second real-time battery state of charge, wherein the charging method includes either the first charging method or the second charging method.

[0055] In one feasible implementation, the battery charging method for the vehicle is determined based on the first real-time battery state of charge (SOC1), the first real-time battery health state (SOH1), and the second real-time battery state of charge (SOC2). This includes: when the first real-time battery state of charge (SOC1) satisfies: SOC1 < SOC1_high, the first real-time battery health state (SOH1) satisfies: SOH1 ≥ SOH1_healthy, and the second real-time battery state of charge (SOC2) satisfies: SOC2 > SOC2_work, the charging method is the first charging method. Here, SOC1_high represents the battery state of charge depletion threshold, SOH1_healthy represents the battery health state compliance threshold, and SOC2_work represents the battery state of charge working threshold of the vehicle's power battery. When the first real-time battery state of charge (SOC1) satisfies: SOC1 < SOC1_high, the first real-time battery health state (SOH1) satisfies: SOH1 < SOH1_healthy, and the second real-time battery state of charge (SOC2) satisfies: SOC2 > SOC2_work, the charging method is the second charging method.

[0056] It should be noted that when the first real-time state of charge (SOC1) of the battery satisfies SOC1 ≥ SOC_high, it indicates that the remaining battery power is sufficient. At this time, the vehicle is controlled to enter normal sleep mode, and no additional power is supplied to the battery. It should also be noted that the embodiments of the present invention do not limit the specific values ​​of the battery state of charge depletion threshold, the battery health status compliance threshold, and the battery state of charge operating threshold of the vehicle power battery. Those skilled in the art can set these values ​​according to actual conditions.

[0057] S230. Control the vehicle power battery to charge the vehicle battery according to the charging method. When the charging method is the first charging method, control the vehicle power battery to charge the vehicle battery. When the charging method is the second charging method, first control the pulse activator to output pulse current to the vehicle battery to perform desulfurization treatment on the vehicle battery, and then control the vehicle power battery to charge the vehicle battery.

[0058] For example, if the SOC1 of the vehicle battery is less than SOC1_high and SOH1 is greater than or equal to SOH1_healthy, the vehicle battery is determined to be healthy but low in power. In this case, the vehicle battery charging device in this embodiment of the invention will further check whether the SOC2 of the vehicle power battery is higher than its working threshold. If SOC2 > SOC2_work, the device will activate the DC-DC converter (DCDC converter) connected between the vehicle battery and the vehicle power battery to control the vehicle power battery to charge the vehicle battery.

[0059] If the vehicle battery's SOC1 < SOC1_high and SOH1 < SOH1_healthy, the vehicle battery is determined to have severe sulfation and be in poor health. In this case, the vehicle battery charging device in this embodiment of the invention will first activate the pulse activator, controlling it to emit a pulse current of a specific frequency and amplitude to desulfate the vehicle battery plates. After desulfation is completed, if the vehicle power battery's SOC2 > SOC2_work, the DC-DC converter (DCDC converter) electrically connected between the vehicle battery and the vehicle power battery will be activated to control the vehicle power battery to charge the vehicle battery. It should be noted that the pulse activator in this embodiment of the invention can be integrated with the DC-DC converter (DCDC converter), realizing the integration and reuse of hardware functions, improving system reliability, and reducing overall cost.

[0060] This invention, targeting sulfated vehicle batteries, pioneers a "repair first, charge later" approach. By using high-frequency pulses to break up lead sulfate crystals, the internal resistance of the battery can be reduced, restoring its charging activity and fundamentally solving the problem of sulfated batteries being unable to charge.

[0061] In one feasible implementation, controlling the vehicle power battery to charge the vehicle storage battery includes: controlling the vehicle power battery to charge the vehicle storage battery until a first real-time battery health state SOC1 satisfies: SOC1≥SOC1_high, where SOC1_high represents the battery state of charge depletion threshold of the vehicle storage battery.

[0062] It should be noted that if the first real-time battery health state SOC1 of the vehicle battery satisfies: SOC1≥SOC1_high, it means that the vehicle battery has sufficient charge and does not need to be recharged. Therefore, it is not necessary to control the vehicle power battery to charge the vehicle battery. Thus, this embodiment of the invention sets the vehicle power battery to charge the vehicle battery until the first real-time battery health state SOC1 satisfies: SOC1≥SOC1_high.

[0063] In another feasible implementation, controlling the vehicle power battery to charge the vehicle storage battery includes: controlling the vehicle power battery to charge the vehicle storage battery until the charging time of the vehicle power battery to the vehicle storage battery reaches a preset charging time.

[0064] It is understandable that prolonged charging may cause the battery to overheat and leak, and in extreme cases, even lead to fire or explosion. This embodiment of the invention protects the battery and improves charging safety by setting an upper limit on the charging time, while also preventing energy waste. It should be noted that this embodiment of the invention does not limit the specific value of the preset charging time; those skilled in the art can set it according to actual conditions.

[0065] In one feasible implementation, controlling the pulse activator to output a pulse current to the vehicle battery to perform desulfurization treatment on the vehicle battery includes: controlling the pulse activator to output a pulse current to the vehicle battery to perform desulfurization treatment on the vehicle battery, and continuously preset the desulfurization time.

[0066] It is understandable that the principle of pulse desulfurization is to decompose lead sulfate crystals using pulsed current at a specific frequency. However, if the time is too long, the continuous pulse impact will break through the battery plate coating, or cause plate deformation and loss of active material, thus accelerating battery degradation. By setting an upper limit on the time, the processing time can be precisely controlled, completing desulfurization without damaging the battery structure. It should be noted that the specific value of the preset desulfurization time in the embodiments of the present invention is not limited, and those skilled in the art can set it according to the actual situation.

[0067] The embodiments of the present invention can achieve efficient replenishment of healthy batteries and repair before recharging of sulfided batteries, thereby improving replenishment efficiency, reducing energy waste, reducing the power consumption of vehicle power batteries, extending the service life of lead-acid batteries (2-3 times), reducing user replacement costs, and reducing environmental pollution.

[0068] Based on the same inventive concept, this invention also provides a vehicle battery charging device.
