Intelligent charging method and charger with activation function

Abstract

The present invention provides an intelligent charging method and charger with an activation function. If the charger can identify the battery and the clamp is connected correctly, it directly enters charging mode. If the clamp is not connected correctly, a prompt message is generated. If the charger cannot identify the battery, a pulse current is input to determine the battery condition. If the battery can be saved, the battery is saved and then enters charging mode after the rescue is complete. If the battery cannot be saved, a prompt message is generated indicating that the battery is bad. This allows the battery to be saved, saving resources and costs.

Description

Technical Field

[0001] The present invention relates to the technical field of battery charging, and in particular to an intelligent charging method and charger with an activation function. Background Art

[0002] Lead-acid batteries are batteries with electrodes primarily made of lead and its oxides, and an electrolyte consisting of a sulfuric acid solution. As one of the safest batteries, they have long been widely used in industries such as energy storage and automotive. However, due to improper use by consumers, they are often prone to over-discharge, which causes the battery voltage to drop to a very low level. For many consumers, when they use a charger to charge their batteries, they find that the charger does not recognize that they are batteries that need to be charged. The voltage of the over-discharged battery is so low that the charger thinks it is not a battery or that it is completely damaged and cannot be charged. In fact, these batteries are only temporarily shocked, not completely dead. If thrown away and not used, it will result in a huge waste.

[0003] Current chargers on the market require the battery voltage to be above a certain level before charging. If the battery voltage falls below this minimum charging voltage, the charger cannot recognize it as a battery and will not charge the battery. This causes the battery to die due to prolonged periods of lack of charge, resulting in unnecessary waste and environmental pollution. Summary of the Invention

[0004] Based on the above problems, the present invention provides an intelligent charging method and charger with activation function, aiming to solve the technical problems in the prior art such as the battery voltage being too low causing the charger to be unable to recognize charging.

[0005] An intelligent charging method with activation function comprises the following steps:

[0006] Step A1: After the battery to be charged is connected to the charger clip, the battery to be charged is identified and output is output whether the battery to be charged is identified:

[0007] If yes, proceed to step A2;

[0008] If not, proceed to step A4;

[0009] Step A2: Check whether the clip is connected correctly:

[0010] If yes, proceed to step A3;

[0011] If not, a prompt message indicating a clip connection error will be generated;

[0012] Step A3, controlling the charger to enter a normal charging mode to charge the battery normally;

[0013] Step A4, controlling the charger to enter a detection and judgment mode, outputting a pulse current to the battery to be charged;

[0014] Step A5: After the pulse current ends, determine whether the battery to be charged can be saved and whether the clamp is connected correctly based on the detected output signal of the battery to be charged:

[0015] If the battery to be charged can be saved and the clip is connected correctly, proceed to step A6;

[0016] If the battery to be charged can be saved but the clamp is connected incorrectly, a prompt message "The battery can be saved but the clamp is connected incorrectly" is generated;

[0017] If the battery to be charged cannot be saved, a message indicating that the battery to be charged is broken is generated and the system then exits.

[0018] Step A6: Control the charger to enter the rescue mode to output a rescue current for a preset time period to the battery to be charged, and determine whether the rescue is successful:

[0019] If yes, proceed to step A7;

[0020] If not, a prompt message indicating battery rescue failure is generated;

[0021] Step A7: Control the charger to enter a normal charging mode to charge the battery normally.

[0022] Furthermore, in step A3 and step A7, the charger is automatically controlled to enter a normal charging mode, or is controlled to enter a normal charging mode based on an external first input;

[0023] In step A6 , the charger is automatically controlled to enter the rescue mode, or is controlled to enter the rescue mode based on an external second input.

[0024] Furthermore, step A5 includes:

[0025] When it is detected that the output terminal voltage of the battery to be charged increases, it is determined that the battery to be charged can be saved and the clamp is connected correctly;

[0026] When it is detected that the output terminal voltage of the battery to be charged is reduced, it is determined that the battery to be charged can be saved and the clamp connection is incorrect;

[0027] When the voltage at the output terminal of the battery to be charged is not detected and a pulse current is received at the output terminal of the battery to be charged, it is determined that the battery to be charged cannot be saved.

[0028] Furthermore, step A6 includes:

[0029] Step A601, outputting a rescue current for a preset time period to the battery to be charged to pre-charge the battery;

[0030] Step A602: After the preset time period ends, the output voltage of the battery to be charged is detected;

[0031] Step A603: Determine whether the output voltage of the battery to be charged is above a preset identification voltage:

[0032] If so, the rescue is judged to be successful;

[0033] If not, it is judged that the rescue failed.

[0034] Furthermore, step A6 includes:

[0035] Step A601: outputting a rescue current for a preset time period to the battery to be charged to perform a first pre-charging of the battery to be charged;

[0037] Step A603: Determine whether the output voltage of the battery to be charged is above a preset identification voltage:

[0038] If so, the rescue is judged to be successful;

[0039] If not, continue to step A604;

[0040] Step A604: outputting a rescue current for a preset time period to the battery to be charged to perform a second pre-charging of the battery to be charged;

[0041] Step A605: After the second pre-charging is completed, the output terminal voltage of the battery to be charged is detected, and the process continues to step A606;

[0042] Step A606: Determine whether the output voltage of the battery to be charged is above a preset identification voltage:

[0043] If so, the rescue is judged to be successful;

[0044] If not, it is judged that the rescue failed.

[0045] Furthermore, in step A3, the normal charging module and the charging switch module connected to the normal charging module are controlled to be turned on, so that the normal charging module outputs a charging current to the battery to be charged for normal charging;

[0046] In step A6, the current generator and the charging switch module connected to the current generator are controlled to be turned on, so that the current generator outputs a rescue current to the battery to be charged for pre-charging;

[0047] Among them, the current generator is pre-configured according to the charging current of the charger:

[0048] When the charging current of the charger is less than a first preset current, the normal charging module is configured to function as a current generator;

[0049] When the charging current of the charger is greater than the first preset current, the normal charging module and the current generator are different modules.

[0050] Furthermore, in step A601, a second preset current is set as an input source of the current generator, the magnitude of the rescue current is detected, and the second preset current is adjusted in real time based on the rescue current.

[0091] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0092] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0093] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0094] See also Figure 1 The present invention provides an intelligent charging method with an activation function, comprising the following steps:

[0095] Step A1: After the battery to be charged is connected to the charger clip, the battery to be charged is identified and output is output whether the battery to be charged is identified:

[0096] If yes, proceed to step A2;

[0097] If not, proceed to step A4;

[0098] Step A2: Check whether the clip is connected correctly:

[0099] If yes, proceed to step A3;

[0100] If not, a prompt message indicating a clip connection error will be generated;

[0101] Step A3, controlling the charger to enter a normal charging mode to charge the battery normally;

[0102] Step A4, controlling the charger to enter a detection and judgment mode, outputting a pulse current to the battery to be charged;

[0103] Step A5: After the pulse current ends, determine whether the battery to be charged can be saved and whether the clamp is connected correctly based on the detected output signal of the battery to be charged:

[0104] If the battery to be charged can be saved and the clip is connected correctly, proceed to step A6;

[0105] If the battery to be charged can be saved but the clamp is connected incorrectly, a prompt message "The battery can be saved but the clamp is connected incorrectly" is generated;

[0106] If the battery to be charged cannot be saved, a message indicating that the battery to be charged is broken is generated and the system then exits.

[0107] Step A6: Control the charger to enter the rescue mode to output a rescue current for a preset time period to the battery to be charged, and determine whether the rescue is successful:

[0108] If yes, proceed to step A7;

[0109] If not, a prompt message indicating battery rescue failure is generated;

[0110] Step A7: Control the charger to enter a normal charging mode to charge the battery normally.

[0111] Furthermore, in step A3 and step A7, the charger is automatically controlled to enter a normal charging mode, or is controlled to enter a normal charging mode based on an external first input;

[0112] In step A6 , the charger is automatically controlled to enter the rescue mode, or is controlled to enter the rescue mode based on an external second input.

[0113] If the voltage of the battery to be charged is above the preset recognition voltage (the preset recognition voltage is also the minimum recognition voltage and the minimum charging voltage of the charger), the charger can recognize the battery and, when the charger determines that the clip is properly connected to the battery, it will generate a prompt to inform the user that charging is possible. Specifically, this notification is made via an LED or LCD. At this point, the charger automatically activates the normal charging module to charge the battery to be charged, i.e., charging according to the default setting. Alternatively, the normal charging module can be activated based on external user input, such as by pressing the charge button.

[0114] If the charger can identify the battery, that is, the battery voltage is above the minimum identification voltage, but determines that the clip is not connected correctly, a prompt message indicating that the clip is not connected correctly is generated to inform the user. After the user disconnects the clip and reconnects it, the charger continues to identify the battery to be charged. If the battery to be charged and the clip are correctly connected, the battery to be charged can be charged normally. Specifically, the user is notified of the incorrect clip connection via an LED or LCD. Further, step A5 includes:

[0115] When it is detected that the output terminal voltage of the battery to be charged increases, it is determined that the battery to be charged can be saved and the clamp is connected correctly;

[0116] When it is detected that the output terminal voltage of the battery to be charged is reduced, it is determined that the battery to be charged can be saved and the clamp connection is incorrect;

[0117] When the voltage at the output terminal of the battery to be charged is not detected and a pulse current is received at the output terminal of the battery to be charged, it is determined that the battery to be charged cannot be saved.

[0118] If the charger cannot recognize the battery, it may be that the battery voltage is too low, indicating over-discharge, below the charger's minimum recognition voltage, or the battery is already defective. Further evaluation of the battery is necessary. This is done by inputting a pulse current into the battery and collecting the output signal to determine the battery's condition and whether the clamps are correctly connected, thereby determining whether the battery can be salvaged.

[0119] In another preferred embodiment of the present invention, if the charger cannot identify the battery to be charged, in step A4, the charger generates a prompt message to inform the user that the clamp is not connected to the battery. The user can then press a detection button to activate the rescue detection function, which generates a pulse current to determine whether the battery to be charged can be rescued and whether the clamp is connected incorrectly. A voltage detection module is added to detect the output voltage of the battery, and a pulse receiving module is added to receive the pulse current at the battery output.

[0120] After applying the pulse current, the output voltage of the battery is detected to rise. If no pulse current is received at the battery output, it means that the battery to be charged can be saved and the clamp is connected correctly. This activates the rescue mode, and the charger generates a controllable rescue current and voltage to activate the battery. Specifically, the rescue current can be a pulse current or a constant current. After the rescue time is over, the charger detects the output voltage of the battery to be charged. If the battery is above the preset identification voltage, it is considered that the charger can identify the battery to be charged, that is, the charger detects that the battery has voltage and is a rechargeable battery. At this time, it automatically enters the charging mode or waits for the consumer to manually select charging to enter the normal charging mode.

[0121] If the battery output voltage drops after applying the pulse current and the battery output voltage is not received, it indicates that the battery can be salvaged, but the clamp connection is incorrect. A prompt message will be displayed to inform the user that the battery can be salvaged, but the clamp connection needs to be reconnected. After the connection is correctly reconnected, continue with step A1 or directly press the rescue button to initiate rescue mode.

[0122] After the pulse current is applied, the output terminal voltage of the battery is not detected, but the pulse current of the battery output terminal is received, indicating that the battery is broken and cannot be saved, and a prompt message indicating that the battery cannot be saved is generated.

[0123] See also Figure 2 , further, step A6 includes:

[0124] Step A601, outputting a rescue current for a preset time period to the battery to be charged to pre-charge the battery;

[0125] Step A602: After the preset time period ends, the output voltage of the battery to be charged is detected;

[0126] Step A603: Determine whether the output voltage of the battery to be charged is above a preset identification voltage:

[0127] If so, the rescue is judged to be successful;

[0128] If not, it is judged that the rescue failed.

[0129] See also Figure 3 , further, step A6 includes:

[0130] Step A601: outputting a rescue current for a preset time period to the battery to be charged to perform a first pre-charging of the battery to be charged;

[0131] Step A602: After the first pre-charging is completed, the output terminal voltage of the battery to be charged is detected, and the process continues to step A603;

[0132] Step A603: Determine whether the output voltage of the battery to be charged is above a preset identification voltage:

[0133] If so, the rescue is judged to be successful;

[0134] If not, continue to step A604;

[0135] Step A604: outputting a rescue current for a preset time period to the battery to be charged to perform a second pre-charging of the battery to be charged;

[0136] Step A605: After the second pre-charging is completed, the output terminal voltage of the battery to be charged is detected, and the process continues to step A606;

[0137] Step A606: Determine whether the output voltage of the battery to be charged is above a preset identification voltage:

[0138] If so, the rescue is judged to be successful;

[0139] If not, it is judged that the rescue failed.

[0140] If the battery is charged in rescue mode and the rescue time expires but the battery voltage still fails to reach a preset identification voltage, a battery unrecoverable prompt message is generated. Preferably, if the battery voltage still fails to reach a preset identification voltage after the first rescue time expires, a rescue current is generated again to rescue the battery a second time. If the battery voltage still fails to reach a preset identification voltage after the rescue time expires, a battery unrecoverable prompt message is generated. Preferably, if the battery voltage still fails to reach a preset identification voltage, a battery unrecoverable prompt message is generated. The user can press the rescue button again to perform a second rescue. If the voltage still fails to reach a preset identification voltage, the battery unrecoverable prompt message is generated.

[0141] When a lead-acid battery receives a rescue current, its voltage rises rapidly. Once the voltage exceeds the preset identification voltage, the charger can enter the normal charging phase. If the rescue current fails to raise the battery above the preset identification voltage, the charger will notify the consumer to try again. If activation continues, the consumer is informed that the battery is no longer rechargeable. This technology significantly increases the likelihood of battery rescue and recharging, saving significant costs.

[0142] Specifically, the user can press the rescue button to activate the rescue function. When the rescue button is pressed, if it is the LCD interface, the charger will remind the user to pay attention to whether the clip is connected correctly, and further let the user ensure that the clip is connected correctly, avoiding the tedious rescue operation when the clip is not connected correctly, and then need to reconnect it.

[0143] Furthermore, in step A3, the normal charging module and the charging switch module connected to the normal charging module are controlled to be turned on, so that the normal charging module outputs a charging current to the battery to be charged for normal charging;

[0144] In step A6, the current generator and the charging switch module connected to the current generator are controlled to be turned on, so that the current generator outputs a rescue current to the battery to be charged for pre-charging;

[0145] Among them, the current generator is pre-configured according to the charging current of the charger:

[0146] When the charging current of the charger is less than a first preset current, the normal charging module is configured to function as a current generator;

[0147] When the charging current of the charger is greater than the first preset current, the normal charging module and the current generator are different modules.

[0148] Specifically, in step A4, the current generator and the pulse switch module connected to the current generator are controlled to be turned on, so that the current generated by the current generator is modulated into a pulse current and then output to the battery to be charged.

[0149] Specifically, if the charging current of the charger used is relatively small, generally for charging smaller lead-acid batteries, there is no need to set up a current generator, which increases the cost and complexity of the charger. The normal charging module is used as a current generator to provide pulse current and rescue current, reducing the internal structure of the charger.

[0150] Specifically, if the charging current of the charger used is relatively large, generally for larger lead-acid batteries, then there is no need to use a relatively large charging current in the rescue mode. Therefore, a current generator is designed separately to provide pulse current and rescue current.

[0151] Furthermore, in step A601, a second preset current is set as an input source of the current generator, the magnitude of the rescue current is detected, and the second preset current is adjusted in real time based on the rescue current.

[0152] Some chargers can detect the rescue current, while some cannot. If the rescue current can be detected, the second preset current can be adjusted in real time based on the rescue current output by the current generator and compared with the second preset current. This allows the rescue current to be controlled, which can help the battery quickly boost voltage in rescue mode.
