With the continuous development of science and technology, batteries are increasingly widely used in daily production and life. Currently, more and more electrical devices include two or more independent battery management systems (Battery Management System, BMS). When charging for the power utilization device, the user needs to operate the power supply side and be connected with every BMS respectively, just can charge to the battery that BMS corresponds, consequently, to the power utilization device including a plurality of BMS, the user needs to operate the power supply side many times and be connected with every BMS, leads to charging process complex operation.
In the related art, in order to facilitate the power supply side to charge the battery corresponding to each BMS at the same time, a plurality of charging interfaces are often set in the power utilization device, and accordingly, when the power utilization device is charged, a user also needs to use a plurality of power supply sides to be connected with the charging interfaces respectively, and after the connection is established between the plurality of power supply sides and the plurality of charging interfaces, the power supply sides are communicated with the BMS, so that synchronous charging of the plurality of batteries is realized, and the user does not need to switch the connection between the power supply sides and different charging interfaces. But the mode of the multi-charging-point interface brings the trouble of searching a power supply party for a user. Taking an example that the electricity utilization device is a vehicle, when the vehicle comprises two BMSs and two charging interfaces respectively corresponding to the two BMSs, a user needs to find two charging piles to charge batteries respectively corresponding to the two BMSs at the same time; or, the user charges the vehicle by self-building the charging piles, and two charging piles are also required to be built, which in turn increases the vehicle use cost of the user. Therefore, in the related art, a plurality of independent BMSs, because the battery corresponding to each BMS needs to be charged independently, the user needs to plug the power supply facilities and the arrangement lines of the corresponding power supply party, the charging process is complicated, and the charging duration and the user waiting duration are increased as a whole.

The charging control device comprises an input module, a charging switch module and a control module. The input module is used for being connected with the charging pile, the charging switch module is used for being connected with at least one battery, and each battery corresponds to a battery management system BMS. Based on this, a plurality of BMSs in the power consumption device can be aggregated by the charge control device. Specifically, when the electric device needs to be charged, the control module may be respectively connected to each BMS in a communication manner, so as to obtain charging parameter information of one or more batteries, and further determine first target charging parameter information by combining each charging parameter information. Next, the control module transmits first target charging parameter information to the charging post so that the charging post charges each first target battery according to the first target charging parameter information without manually switching the communication connection BMS with the charging post by a user. Meanwhile, the control module controls the charging loop where each first target battery is located to be conducted, so that one or more batteries are respectively charged through one charging pile, and the charging process is effectively simplified.
In addition, because the battery that corresponds respectively for a plurality of BMSs in the power consumption device can be charged simultaneously through charging control device, consequently, the user only need find a charging stake, both can realize the battery that corresponds respectively for a plurality of BMSs in the power consumption device through once operation and charge, effectively simplify the charging process, reduce the duration of charging and reduce user's waiting duration. In addition, based on the embodiment of the application, the user does not need to additionally establish and use redundant charging piles, so that the cost of the user is saved.

The charging control device transmits a charging request to each BMS in the electricity consumption device in response to the connection with the charging stake, so that each BMS determines whether to allow the charging stake to charge the battery corresponding to the own system. Alternatively, after acquiring the power supply information of the charging pile, the charging control device may use the power supply information as a part of the charging request, so that the BMS determines whether to allow the charging pile to charge the battery corresponding to the system according to the power supply information. Wherein, BMS can combine the factors such as there is difference, battery performance variation of different batteries in the use between the different battery individuals, judge whether current charging stake can satisfy the charge demand of the battery that self system corresponds to under the circumstances that satisfies the charge demand, allow charging stake to the battery that self system corresponds to, and under the circumstances that does not satisfy the charge demand, not allow charging stake to the battery that self system corresponds to, thereby improve battery charging process's reliability, reduce to cause life-span decay faster, overcharge, battery uniformity is less than the damage such as.
According to the embodiment of the application, after the charging control device establishes connection with the charging piles, the charging request information is sent to the M BMSs, and the user does not need to manually switch the BMSs in communication connection with the charging piles, so that the communication between the charging piles and the BMSs is realized.

Step 5201, determining a first number of first target batteries and a first charging current of each first target battery;
in step 5202, a first target charging current is determined based on the minimum charging current of the first charging currents and the first number of first target batteries.
Illustratively, the first charging current in the charging parameter information may include, but is not limited to, a current range allowed for battery charging, a maximum current value allowed for battery charging, and the like.
The charging control device can determine the first target battery to be charged according to the received charging parameter information, and obtain the first charging current corresponding to each first target battery, so that the minimum charging current in the required charging battery can be obtained.
The first target charging current is obtained by determining the minimum charging current of the m first charging currents and calculating the product of the minimum charging current and the number of the first target batteries.
Optionally, the first target charging parameter information may further include a charging voltage of the battery, wherein the charging voltage of the charging post needs to be greater than the voltage of the battery.
According to the embodiment of the application, the first target charging current is determined by determining the first number m of the first target batteries and the minimum charging current in the m first charging currents. Based on the above, when the charging pile outputs the charging current based on the first target current, the problem that the battery may have overcurrent can be solved, so that the reliability of the charging process is improved, and the service life of the battery is prolonged.
In some embodiments, after sending the first target charging parameter information to the charging pile and controlling the charging loop where each first target battery in the charging control device is located to be turned on, the charging control method further includes steps 601 to 603.
Step 601, receiving charging completion information of n second target batteries, wherein the second target batteries are charged batteries in m first target batteries, and n is more than or equal to 1 and less than or equal to m;

and 603, controlling the charging loops where the n second target batteries are located to be disconnected.
The second target charging parameter information comprises a preset charging current, and the preset charging current is smaller than the first target charging current.
Specifically, referring to step 601, the second target battery is a charged battery in the m first target batteries, and after the second target battery is charged, the BMS corresponding to the second target battery may send charging completion information to the charging control device, so that the charging control device timely disconnects the charging loop, so as to reduce the occurrence of overcharge of the second target battery.
The number of the second target batteries may be 1 or more, and it is understood that the number of the second target batteries is less than or equal to the number of the first target batteries.
Next, referring to the above-described steps 602 and 630, the charge control device transmits second target charging parameter information to the charging post in response to the charging completion information of the second target battery, so that the charging post charges each of the first target batteries according to the second target charging parameter information.
For example, the second target charging parameter information may include a preset charging current, and the preset charging current is smaller than the first target charging current. Alternatively, the preset charging current may be determined according to a working current range in which the switching submodule in the charging control device normally performs switching.
When the charging loop where the second target battery is located is controlled to be disconnected, the method specifically may include controlling a switch sub-module in the charging loop where the second target battery is located to be disconnected, so as to disconnect the charging loop. Optionally, the switch sub-module includes a switching element such as a relay.
According to the embodiment of the application, after receiving the charging completion information of the second target battery, the second target charging parameter information is sent to the charging pile, and the preset charging current is smaller than the first target charging current because the preset charging current is included in the second target charging parameter information, so that the output current of the charging pile can be reduced. And then, the charging loops where the n second target batteries are positioned are controlled to be disconnected, so that a switch sub-module in the charging loops can be protected, the service life of the switch sub-module is prolonged, and the reliability of charging the batteries is improved.
In some embodiments, after controlling the charging circuits of the n second target batteries to be disconnected, the method may further include step 604 and step 605.

Specifically, in the case where n is smaller than m, it is explained that among the m first target batteries, a battery whose charging is not completed is further included, and for convenience of description, the battery whose charging is not completed among the m first target batteries is hereinafter referred to as a third target battery.
Then, the charging control device may automatically determine the charging parameters required by the remaining third target battery, obtain third target charging parameter information, and send the third target charging parameter information to the charging pile, so that the charging pile charges the battery which is not charged in the first target battery according to the third target charging parameter information.
According to the embodiment of the application, after the charging loop where the second target battery is located is disconnected, the charging parameter information is determined again and sent to the charging pile, so that the battery which is not charged in the first target battery is charged continuously, the charging parameter can be automatically adjusted without manual operation of the charging battery by a user, the charging process is effectively simplified, and the convenience is improved.
In some embodiments, determining the third target charging parameter information according to the charging parameter information corresponding to each third target battery includes:
determining a second number corresponding to the third target battery according to the first number of the first target battery and the number of the second target battery;

Specifically, the number of the first target batteries is m, the number of the second target batteries is n, and the second number corresponding to the third target batteries can be obtained through calculation.
Alternatively, the charging parameter information corresponding to each third target battery may be transmitted to the charging control device by the BMS. For example, after the charging control device establishes connection with the charging pile every time, the charging control device sends a charging request to each BMS, the BMS feeds back charging parameter information of a battery corresponding to the system of the BMS to the charging control device, and the charging control device caches the charging parameter information of each battery until the charging is completed, and the charging control device can select to keep or delete the charging parameter information in the cache.
In the embodiment of the application, the charging control device may obtain third charging parameter information corresponding to each third target battery from the cache, so as to obtain a second charging current corresponding to each third target battery. The second charging current may include, but is not limited to, a current range allowed by battery charging, a maximum current value allowed by battery charging, and the like.
Next, the second target charging current is obtained by determining the smallest charging current among all the second charging currents, and calculating the product of the smallest charging current and the number of the third target batteries.
In the embodiment of the application, the second target charging current is determined according to the minimum charging current in the second charging current and the second number of the third target battery by acquiring the number of batteries which are not charged in the first target battery and acquiring the minimum charging current in the second charging current of the batteries which are not charged. Based on the method, the output current of the charging pile can be updated in time, and when the charging pile outputs the charging current based on the second target current, the problem that the battery possibly has overcurrent can be solved, so that the reliability of the charging process is improved, and the service life of the battery is prolonged.
In some embodiments, in charging each first target battery, the method further comprises: receiving fault alarm information sent by the BMS; and sending charging stopping information to the charging pile in response to the fault alarm information, and controlling the charging loop where each first target battery in the charging control device is located to be disconnected.
Specifically, each BMS in the power consumption device may detect in real time whether a battery corresponding to its own system has a fault, for example, a battery temperature rise abnormality, etc., and at this time, the BMS may generate fault alarm information and transmit the fault alarm information to the charge control device.
And after receiving the fault alarm information, the charging control device sends charging stopping information to the charging pile and controls the charging loop of each first target battery in the charging control device to be disconnected, so that the charging of the battery in the power utilization device is stopped.
In the embodiment of the application, the fault alarm information of the BMS can be responded in real time, so that the charging pile can be timely informed to stop power supply, and the charging loop is disconnected, so that the reliability of the charging process is improved.
