The charging control method can be applied to the charger 100 shown in fig. 1, and the specific flow shown in fig. 3 will be described in detail below.
And step S101, after the charger is successfully connected with the intelligent battery, acquiring a charging overcurrent threshold of the intelligent battery.
In this embodiment, after the communication line between the charger 100 and the smart battery 200 is successfully connected and handshake established, the charger 100 may obtain the charging parameters including the charging overcurrent threshold I of the smart battery 200 from the smart battery 200 through the communication lineoCharging voltage VcAnd the like.
And S102, setting an initial output current value of the charger according to the charging overcurrent threshold, and charging the intelligent battery according to the initial output current value so that the intelligent battery does not generate charging overcurrent.
In the present embodiment, the charger 100 is based on the charging overcurrent threshold I of the smart battery 200oAfter the initial output current value of the charger 100 is reasonably set, it can be ensured that the intelligent battery 200 does not start charging protection due to charging overcurrent at the beginning of charging, and the electric quantity of the intelligent battery 200 can be fully charged at a faster charging speed through the set initial output current value. Wherein, the charger 100 may charge the smart battery 200 with the set initial output current value through the power line.
And step S103, acquiring a real-time charging current value acquired by the intelligent battery.
The charger 100 may obtain the real-time charging current value collected by the smart battery 200 through the communication line in the process of charging the smart battery 200.
And step S104, judging whether the real-time charging current value is smaller than the reference current value.
The reference current value may be calculated by the charger 100 according to the charging overcurrent threshold, the first preset current value, and the second preset current value of the smart battery 200.
Specifically, the reference current value may be according to formula Ia＝(IoCalculated as-delta) -delta/2, wherein IaFor reference current value, IoIn order to charge the overcurrent threshold, delta/2 is a first preset current value, and delta is a second preset current value.
It should be noted that Δ is a constant set in the charger 100, and Δ cannot approach the accuracy of current sampling to avoid the current-dependent samplingCauses the actual charging current of the smart battery 200 to exceed the charging overcurrent threshold Io。
In this embodiment, after acquiring the real-time charging current value collected by the smart battery 200, the charger 100 determines whether the real-time charging current value is smaller than the calculated reference current value, if so, performs step S105, and if so, performs step S106.
And S105, if the real-time charging current value is smaller than the reference current value, increasing a first preset current value on the basis of the initial output current value to obtain a new output current value, and charging the intelligent battery by taking the new output current value as the initial output current value.
In one example, the first preset current value may be Δ/2, assuming that the real-time charging current value obtained by the charger 100 is IrThe initial output current value set in the charger 100 is IeWhen the charger 100 determines the real-time charging current value IrLess than a reference current value Ia＝(Io-delta/2, at the initial output current value IeOn the basis of the first preset current value delta/2, a new output current value, namely I is obtainede+ Δ/2, and charging the smart battery 200 with the new output current value as the initial output current value, which is equivalent to resetting the initial output current value I of the charger 100e＝Ie+ delta/2, so as to continuously adjust the initial output current value I set by the charger 100 during the charging processeControlling the current output of the charger 100 until the real-time charging current value obtained by the charger 100 is greater than or equal to the reference current value Ia。
In step S106, if the real-time charging current value is greater than or equal to the reference current value, the initial output current value is maintained unchanged.
In this embodiment, when the charger 100 continuously adjusts the set initial output current value to finally make the real-time charging current value collected by the intelligent battery 200 be greater than or equal to the reference current value, the currently set initial output current value is maintained unchanged, that is, the initial output current value is not adjusted any more, and at this time, the charging current of the intelligent battery 200 reaches a stable state.
Alternatively, in step S102, in order to prevent the smart battery 200 from starting the charging protection due to the charging overcurrent as soon as the charging is started, and to fully charge the smart battery 200 with the electric energy at a faster charging speed, the initial output current value of the charger 100 may be set in the following two ways.
The first method comprises the following steps: comparing the obtained charging overcurrent threshold value with a third preset current value, and if the charging overcurrent threshold value is larger than the third preset current value, setting an initial output current value according to the charging overcurrent threshold value, the second preset current value and the third preset current value; and if the charging overcurrent threshold value is smaller than or equal to a third preset current value, setting an initial output current value according to the charging overcurrent threshold value and the second preset current value.
Specifically, if the charging overcurrent threshold is greater than the third preset current value, the charging overcurrent threshold may be determined according to formula Ie＝Io-Ic+ delta sets the initial output current value; wherein, IeTo an initial output current value, IoFor charging over-current threshold, Δ is a second predetermined current value, IcIs a third preset current value; if the charging overcurrent threshold is less than or equal to the third preset current value, the charging overcurrent threshold can be determined according to the formula Ie＝Io- Δ setting an initial output current value; wherein, IeTo an initial output current value, IoAnd delta is a second preset current value for the charging overcurrent threshold value.
In this embodiment, the third predetermined current value is also a current constant preset in the charger 100, and the magnitude of the third predetermined current value is much larger than the current sampling deviation between the charger 100 and the smart battery 200, for example, if the current sampling deviation is 2A, the third predetermined current value may be set to 10A.
In one example, assume that the third preset current value is IcThe charger 100 obtains the charging overcurrent threshold I of the smart battery 200oCharging voltage VcAfter the charging parameters are equal, judging a charging overcurrent threshold IoWhether the current value is larger than the third preset current value and is IcIf I iso>IcThen, a charger is arranged100 has an output voltage of VcThe initial output current value of the charger 100 is Ie＝Io-Ic+ Δ, if Io≤IcThen the output voltage of the charger 100 is set to VcSetting the initial output current value of the charger 100 to Ie＝Io-Δ。
For example, setting Δ to 1A, IcAt 10A, when the charging overcurrent threshold I of the smart battery 200 is obtainedoAt 32A, due to Io>IcThen the initial output current value I can be sete＝Io-IcWhen the initial output current value set in the charger 100 is 23A, considering the response time and the current sampling difference between the smart battery 200 and the charger 100, the charging current value actually collected by the smart battery 200 may be 21A to 25A, and the charger 100 continuously adjusts the set initial output current value according to the content shown in fig. 3 during the charging process, so that the charger 100 can finally use the charging current I close to the charging overcurrent threshold valuer<IoThe smart battery 200 is charged by 31.5A.
And the second method comprises the following steps: and setting an initial output current value according to the charging overcurrent threshold value, the second preset current value and the preset constant of the intelligent battery 200.
In particular, according to formula Ie＝k×(Io- Δ) setting an initial output current value; wherein, IeIs an initial output current value, k is a predetermined constant, IoAnd delta is a second preset current value for the charging overcurrent threshold value.
The value range of k is 0-1, the intelligent battery 200 can be guaranteed not to be started to be charged and protected due to triggering of charging overcurrent through setting of a proper k value, and the electric quantity of the intelligent battery 200 can be fully charged at a high speed.
For example, when Δ is set to 1A and k is set to 0.6, the charging overcurrent threshold I of the smart battery 200 is obtainedoAt 32A, the initial output current value I can be sete＝k×(Io- Δ) ═ 18.6A. The charger 100 continuously adjusts the set initial output current value according to the content shown in fig. 3 during the charging process, so that the charger 100 can be connectedCharging current I near charging overcurrent thresholdr<IoThe smart battery 200 is charged by 31.5A.
It should be noted that, in this embodiment, for the same charger 100 and smart battery 200, no matter whether the initial output current value set by the charger 100 changes, the current sampling difference between the charger 100 and the smart battery 200 remains substantially unchanged, and no large fluctuation occurs. For example, if the initial output current value set by the charger 100 is 13A and the real-time charging current value collected by the smart battery 200 is 12A, when the initial output current value is set to 14A again, the real-time charging current value collected by the smart battery 200 is approximately 13A.
It can be seen that, after the charger 100 in this embodiment is successfully connected to the smart battery 200, the charger obtains the charging overcurrent threshold of the smart battery 200, and sets a relatively reasonable initial output current value according to the charging overcurrent threshold to charge the smart battery 200, so that the smart battery 200 does not start charging protection due to charging overcurrent at the beginning of charging, and can fully charge the electric quantity of the smart battery 200 at a relatively fast charging speed; in addition, the charger 100 controls the current output of the charger 100 by acquiring the charging current value of the intelligent battery 200 in real time and continuously adjusting the initial output current value set by the charger 100 according to the acquired real-time charging current value and the reference current value, so that the charging current value of the intelligent battery 200 can gradually approach the set current value, and the reference current value is calculated according to the charging overcurrent threshold value, the first preset current value and the second preset current value of the intelligent battery 200, and finally the charger 100 can charge the intelligent battery 200 with the charging current approaching the charging overcurrent threshold value of the intelligent battery 200 and control the charging current of the intelligent battery 200 within the charging overcurrent threshold value, so that the electric quantity of the intelligent battery 200 can be smoothly charged at a faster charging speed, and the situation that when the charger 100 charges the intelligent battery 200 with the charging current approaching the charging overcurrent threshold value is effectively avoided, the smart battery 200 is likely to start charging protection due to the current sampling deviation between the charger 100 and the smart battery 200.
In order to execute the corresponding steps in the above embodiments and various possible modes, an implementation mode of the charging control device is given below. Referring to fig. 4, a functional block diagram of a charging control apparatus 300 according to an embodiment of the present invention is shown. It should be noted that the basic principle and the generated technical effects of the charging control device 300 provided in the present embodiment are the same as those of the above embodiments, and for the sake of brief description, no part of the present embodiment is mentioned, and corresponding contents in the above embodiments may be referred to.

In this embodiment, the current setting module 320 can set the initial output current of the charger 100 in the following two ways.
The first method comprises the following steps: the current setting module 320 is configured to compare the obtained charging overcurrent threshold with a third preset current value, and set an initial output current value according to the charging overcurrent threshold, the second preset current value, and the third preset current value if the charging overcurrent threshold is greater than the third preset current value; and if the charging overcurrent threshold value is smaller than or equal to a third preset current value, setting an initial output current value according to the charging overcurrent threshold value and the second preset current value.
Specifically, the current setting module 320 is configured to, if the charging overcurrent threshold is greater than a third preset current value, set the charging overcurrent threshold according to formula Ie＝Io-Ic+ delta sets the initial output current value; wherein, IeTo an initial output current value, IoFor charging over-current threshold, Δ is a second predetermined current value, IcIs a third preset current value; if the charging overcurrent threshold value is less than or equal to a third preset current value, according to the formula Ie＝Io- Δ setting an initial output current value; wherein, IeTo an initial output current value, IoAnd delta is a second preset current value for the charging overcurrent threshold value.
And the second method comprises the following steps: the current setting module 320 is configured to set an initial output current value according to the charging overcurrent threshold, the second preset current value, and the preset constant of the smart battery 200.
Specifically, the current setting module 320 is configured to set the current according to formula Ie＝k×(Io- Δ) setting an initial output current value; wherein, IeIs an initial output current value, k is a predetermined constant, IoAnd delta is a second preset current value for the charging overcurrent threshold value.
It is understood that the current setting module 320 may perform the above step S102.
The obtaining module 310 may also be configured to obtain a real-time charging current value collected by the smart battery 200.
It is understood that the obtaining module 310 may also perform the step S103.
The determining module 330 is used for determining whether the real-time charging current value is smaller than the reference current value.
The reference current value may be calculated by the charger 100 according to the charging overcurrent threshold, the first preset current value, and the second preset current value of the smart battery 200.
In particular, the reference current value may be according to formula Ia＝(IoCalculated as-delta) -delta/2, wherein IaFor reference current value, IoIn order to charge the overcurrent threshold, delta/2 is a first preset current value, and delta is a second preset current value.
It is understood that the determining module 330 may perform the step S104.
The current setting module 320 is further configured to, if the real-time charging current value is smaller than the reference current value, increase a first preset current value on the basis of the initial output current value to obtain a new output current value, and charge the smart battery 200 with the new output current value as the initial output current value; and if the real-time charging current value is greater than or equal to the reference current value, maintaining the initial output current value unchanged.
It is understood that the current setting module 320 may also perform the above steps S105 and S106.
