Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.

Referring to fig. 1, the present invention provides an intelligent charging method with an activation function, including the following steps:

step A1, after the clip of the charger is connected with the battery to be charged, identifying the battery to be charged and outputting whether the battery to be charged is identified:

if yes, continue step A2;

if not, continue step A4;

step A2, judging whether the clip is correctly connected:

if yes, continue step A3;

if not, generating prompt information of the connection error of the clamp;

step A3, controlling the charger to enter a normal charging mode to charge the battery to be charged normally;

step A4, controlling the charger to enter a detection and judgment mode, and outputting a section of pulse current to the battery to be charged;

step A5, after the pulse current ends, according to the detected output end signal of the battery to be charged, it is judged whether the battery to be charged can be rescued and whether the clip is correctly connected:

if the battery to be charged can be rescued and the clip connection is correct, continuing with step a 6;

if the battery to be charged can be saved but the clip connection is wrong, generating prompt information that the battery can be saved but the clip connection is wrong;

if the battery to be charged can not be rescued, generating a prompt message that the battery to be charged is bad, and then quitting;

step A6, controlling the charger to enter a rescue mode so as to output a rescue current of a preset time period to the battery to be charged and judging whether the rescue is successful:

if yes, continue step A7;

if not, generating prompt information of battery rescue failure;

and step A7, controlling the charger to enter a normal charging mode, and normally charging the battery to be charged.

Further, in step A3 and step a7, automatically controlling the charger to enter a normal charging mode, or controlling the charger to enter the normal charging mode based on an external first input;

in step a6, the charger is automatically controlled to enter a rescue mode, or the charger is controlled to enter the rescue mode based on a second input from the outside.

If the voltage of the battery to be charged is higher than the preset identification voltage, the preset identification voltage is the lowest identification voltage and the lowest charging voltage of the charger. When the voltage of the battery to be charged is higher than the lowest identification voltage, the charger can identify the battery, and when the charger judges that the clamp is connected with the battery correctly, prompt information capable of charging is generated to inform a user. Specifically, the user is informed by means of an LED or LCD. At the moment, the charger automatically starts a normal charging module to charge the battery to be charged, namely, the battery is charged according to a default design; the normal electric module can be turned on based on an external input of a user to perform normal charging for charging, for example, the user presses a charging button to perform normal charging.

If the charger can identify the battery, namely the voltage of the battery is higher than the lowest identification voltage, but the clamp connection is judged to be incorrect, prompt information that the clamp connection is incorrect is generated to inform a user, after the user disconnects the clamp for reconnection, the charger continues to identify the battery to be charged, identifies the battery to be charged and the clamp connection is correct, and then the battery to be charged can be charged normally. Specifically, the user is informed by means of an LED or LCD that the clip is not properly attached. Further, step a5 includes:

when the output end voltage of the battery to be charged is detected to be increased, the battery to be charged is judged to be rescued and the clamp connection is correct;

when the output end voltage of the battery to be charged is detected to be reduced, the battery to be charged is judged to be rescued and the clamp is wrongly connected;

when the output end voltage of the battery to be charged is not detected and the pulse current of the output end of the battery to be charged is received, the battery to be charged is judged to be not rescued.

If the charger cannot identify the battery to be charged, the voltage of the battery to be charged is too low, the battery is over-discharged and is lower than the lowest identification voltage of the charger, or the battery to be charged is not good, the quality of the battery to be charged needs to be further judged. The specific method is that, to waiting to charge battery input one section pulse current, through gathering waiting to charge battery output end signal and judging whether the quality and the clip of waiting to charge battery connect correctly to judge whether waiting to charge battery can save.

As another preferred embodiment of the present invention, if the charger does not recognize the battery to be charged, in step a4, the charger generates a prompt message that the clip is not connected to the battery to notify the user, the user can press the detection button to start the rescue detection function, and the user can determine whether the battery to be charged can be rescued and whether the clip is misconnected by generating a pulse current. A voltage detection module is added to detect the voltage of the output end of the battery, and a pulse receiving module is added to receive the pulse current of the output end of the battery.

Detect the output terminal voltage of battery after applying pulse current and rise, do not receive the pulse current of battery output end, then show that rechargeable battery can save to the clip is connected correctly. Just so open and save the mode, the charger produces a controllable current and voltage of saving and activates the battery, and is concrete, and it can be one section pulse current to save the current, perhaps is the constant current, after saving the time, the charger detects the output voltage of treating rechargeable battery, if the battery is more than predetermineeing identification voltage, then think that the charger can discern and treat rechargeable battery, and the charger detects the battery promptly and has voltage, for rechargeable battery, and at this moment, the automatic mode of charging that gets into or wait for the consumer manual selection to charge and get into normal charging mode.

Detect the output end voltage drop of battery after applying pulse current, not received the pulse current of battery output end, then explain that the battery can save, but the clip connection is wrong. A prompt is generated at this point telling the user that the battery can be saved, but the clip needs to be reconnected. After the reconnection is correct, the operation continues to step a1, or the user directly presses the rescue button to start the rescue mode.

The output end voltage of the battery is not detected after the pulse current is applied, but the pulse current of the output end of the battery is received, so that the battery is damaged and cannot be saved, and prompt information that the battery cannot be saved is generated.

Referring to fig. 2, further, step a6 includes:

step A601, outputting a rescue current of a preset time period to a battery to be charged so as to pre-charge the battery to be charged;

step A602, after a preset time period is over, detecting the voltage of the output end of a battery to be charged;

step a603, determining whether the voltage of the output terminal of the battery to be charged is above a preset identification voltage:

if yes, judging that the rescue is successful;

if not, judging that the rescue fails.

Referring to fig. 3, further, step a6 includes:

step A601, outputting a rescue current of a preset time period to a battery to be charged so as to pre-charge the battery to be charged for the first time;

step A602, after the first pre-charging is finished, detecting the voltage of the output end of the battery to be charged, and continuing to step A603;

step a603, determining whether the voltage of the output terminal of the battery to be charged is above a preset identification voltage:

if yes, judging that the rescue is successful;

if not, continuing to the step A604;

step A604, outputting a rescue current of a preset time period to the battery to be charged so as to perform secondary pre-charging on the battery to be charged;

step A605, after the second pre-charging is finished, detecting the voltage of the output end of the battery to be charged, and continuing to step A606;

step A606, judging whether the output end voltage of the battery to be charged is above a preset identification voltage:

if yes, judging that the rescue is successful;

if not, judging that the rescue fails.

If charge the battery under the mode of saving, the time of saving finishes, and battery voltage still can't reach and predetermine more than the identification voltage, then produce the prompt message that the battery can't be saved. Preferably, the time of saving finishes for the first time, and when battery voltage still can't reach and predetermine more than identification voltage, the electric current of saving is produced again and is rescued the battery for the second time, and the time of saving finishes, and battery voltage still can't reach and predetermine more than identification voltage, just produces the suggestion information that the battery can't save. Preferably, when battery voltage still can't reach and predetermine more than the identification voltage, the prompt message that the battery can't be rescued is produced, and the user can press the rescue button again and carry out the second rescue, still can't reach, indicates that the battery can't be rescued.

After the lead-acid battery obtains the rescue current, the voltage can rise rapidly, and once the voltage exceeds the preset identification voltage, the charger can enter a normal charging stage. If the rescue current does not allow the battery to exceed the preset identification voltage, the charger will notify the consumer to continue once more. If activation continues to be disabled, the consumer is notified that the battery has been disabled. The use of such techniques greatly increases the likelihood of battery rescue to achieve recharging, saving a significant amount of cost.

Specifically, the user can press and save the button and open and save the function, when pressing and saving the button, if be the LCD interface, the charger can notice to the user that whether the clip connects correctly, further lets the user ensure that the clip connects correctly, saves the loaded down with trivial details of operation when avoiding the clip to connect incorrectly, later still need reconnect once.

Further, in step a3, the normal charging module outputs a charging current to the battery to be charged for normal charging by controlling the normal charging module and the charging switch module connected to the normal charging module to be switched on;

in step a6, the current generator is controlled to be switched on with the charging switch module connected with the current generator, so that the current generator outputs a rescue current to the battery to be charged for pre-charging;

wherein, dispose the current generator according to the charging current size of charger in advance:

when the charging current of the charger is less than a first preset current, the normal charging module is configured to be used as a current generator;

when the charging current of the charger is larger than the first preset current, the normal charging module and the current generator are different modules.

Specifically, in step a4, the current generator is controlled to be turned on by the pulse switch module connected to the current generator, so that the current generated by the current generator is modulated into a pulse current and then output to the battery to be charged.

Specifically, if the charging current of the charger that uses is smaller, generally charge to less lead-acid batteries, then need not to set up a current generator again, the complexity of increase cost and charger uses the normal module of charging to provide impulse current and save the electric current as current generator, reduces the inner structure of charger.

Specifically, if the charging current of the charger used is large, the charger is generally directed to a large lead-acid battery, so that the large charging current is not needed to be used in the rescue mode, and therefore, a current generator is designed separately to provide the pulse current and the rescue current.

Further, 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.

Some chargers can detect and save the electric current, some chargers can not detect and save the electric current, if can save the detection of electric current size, save electric current size and the second according to the output of current generator and predetermine the electric current and compare, adjust the second in real time and predetermine the electric current, make like this save the electric current and can control, can help the battery to boost under saving the mode fast.
