Patent CN113131519B (application number: CN 202110449209.6) discloses a home energy management optimization method based on mixed integer linear programming, comprising: 1. constructing an operation model of each load device in the household energy management system; 2. constructing a running model of the household and power grid bidirectional interaction equipment; 3. constructing a household energy management system optimization model with the minimum electricity charge of a user; 4. and solving by adopting a mixed integer linear programming method to obtain the optimal scheduling. The patent CN113131519B aims at the optimization problem of multidimensional constraint of a household energy management system model, so that the optimal dispatching of household load equipment is realized, the electricity cost of a user is reduced, and the household energy optimization control is realized to the maximum. However, in some scenarios (for example, when the user goes out for travel) when the frequency of use of the household energy storage battery is low, the method in the patent CN113131519B and the existing energy storage battery charging control system still charge and discharge the battery according to the full-load working state, which results in large loss of the household energy storage battery, and cannot effectively protect the service life and the use state of the household energy storage battery.

Based on the above, the embodiment of the application provides a wall-mounted energy storage battery, including charging plan subassembly, charging subassembly, battery pack and control assembly, the charging cycle number of battery pack in the future of default time period is confirmed to the charging plan subassembly, and control assembly charges the battery pack according to the charging cycle number control charging subassembly of battery pack in the future of default time period. According to the embodiment of the application, the loss of the household energy storage battery can be reduced according to the use frequency of the household energy storage battery, and the service life of the household energy storage battery is prolonged.

In some scenes, the wall-mounted energy storage battery can be applied to household wall-mounted energy storage batteries, and the service life of the wall-mounted energy storage battery can be prolonged.

The following describes a wall-mounted energy storage battery and a method for controlling efficient charge and discharge thereof according to embodiments of the present application with reference to specific examples.

The existing energy storage battery charging control system is used for charging and discharging the battery according to a full-load working state, namely, the charging process of the battery is kept at the highest charging power most of the time, the highest charging power of the battery is always higher than the rated charging power of the battery, or the temperature of the battery exceeds a normal temperature range in the charging process, so that the household energy storage battery is easily damaged in the charging process, and the loss of the battery in the charging process is larger. Thus, long-term high-power charging may shorten the life of the household energy storage battery.

Fig. 1 is a schematic diagram of a system structure of a household energy storage battery in an embodiment of the present application, as shown in fig. 1, the household energy storage battery in the embodiment of the present application includes a charging schedule component 1, a charging component 2, a battery component 3 and a control component 4, where the charging schedule component 1 determines a charging cycle number of the battery component 3 in a preset time period in the future, and the control component 4 controls the charging component 2 to charge the battery component 3 according to the charging cycle number of the battery component 3 in the preset time period in the future.

In this embodiment of the application, the charging cycle number of the battery assembly 3 in the future preset time period is predicted or determined by the charging plan assembly 1, so that the charging process of the battery assembly 3 can be controlled according to the charging cycle number of the battery assembly 3 in the future preset time period, so that the charging process of the battery assembly 3 is scientifically and reasonably arranged according to the charging cycle number of the battery assembly 3 in the future preset time period when the battery assembly 3 is charged by the charging assembly 2, the loss of the battery assembly 3 caused when the battery assembly 3 is charged by the charging assembly 2 is reduced as much as possible, and the service life of the battery assembly 3 can be prolonged.

Illustratively, when the charging schedule component 1 determines that the number of charging cycles of the battery component 3 in the future preset time period is large, in order to ensure the effect of using the battery component 3, that is, when the battery component 3 fully meets the use requirement of the large number of charging cycles, the charging schedule component 1 can control to increase the power of the charging component 2 for charging the battery component 3, and keep the power of the charging component 2 for charging the battery component 3 smaller than the maximum chargeable power, so that the user experience of using the household energy storage battery can be ensured.

Illustratively, when the charging schedule component 1 determines that the number of charging cycles of the battery component 3 in the future preset time period is small, in order to prolong the service life of the battery component 3, the charging power of the battery component 3 at the time of the small number of charging cycles can be correspondingly reduced, so that the service life of the household energy storage battery in use can be ensured.

For example, in the case where the user uses the home battery pack at a low frequency such as at home without one at home for traveling away from home, the charging power of the battery pack 3 can be reduced accordingly, and the protection effect of the battery pack can be improved.

The implementation method has the beneficial effects that the charging plan of the battery assembly is determined according to the charging cycle times in the future preset time period, the charging power of the battery assembly is reasonably controlled, the use experience of the user of the household energy storage battery can be ensured according to the charging cycle times in the future preset time period, and the service life of the household energy storage battery can be prolonged.

In some implementations, the charging schedule component 1 determines the number of charging cycles of the battery assembly 3 within a predetermined time period in the future based on a control instruction of the user, a location of the mobile powered device, or a usage habit of the user.

For example, the user may directly input a control instruction to the charging schedule component 1, enabling setting of the number of charging cycles within a preset time period in the future.

For example, the charging plan component 1 may communicate with a mobile phone App corresponding to the charging plan component 1, and the user may input the number of charging cycles in a preset time period in the future on the charging plan component 1 corresponding to the mobile phone App, so as to implement setting of the number of charging cycles in the preset time period in the future.

For example, the user may input a number of charging cycles of 1 day/time or 3 days/time for a preset period of time in the future on the charging schedule component 1 corresponding to the mobile phone App.

In a household energy storage system, mobile electrical devices (e.g., electric vehicles) often occupy a large portion of the power consumption of the household energy storage system. Thus, in use, the charging planning assembly 1 may obtain the location of a mobile powered device (e.g. an electric car), and the charging planning assembly 1 in turn predicts the number of charging cycles of the battery assembly 3 within a predetermined time period in the future based on the location of the mobile powered device.

For example, when the mobile electric device (e.g. electric car) is recently used during the travel of the user, the household energy storage system does not need to supply power to the mobile electric device (e.g. electric car), and the number of charging cycles of the battery assembly 3 in a future preset period of time is correspondingly reduced.

For another example, when the mobile electric device (e.g. electric automobile) is recently used on the way of the user going to work and needs to go home for charging, the household energy storage system needs to supply power to the mobile electric device (e.g. electric automobile) every day, and at this time, the number of charging cycles of the battery assembly 3 in a future preset period of time is correspondingly increased.

In a domestic energy storage system, the usage habits of different users are different, so that the number of charging cycles of the battery assembly 3 in a preset time period in the future can be determined by the charging schedule assembly 1.

For example, the first user has a usage habit of using less power to the household energy storage system during monday to thursday and more power to the household energy storage system during friday to sunday, and accordingly the charging schedule component 1 can predict a corresponding decrease in the number of charging cycles of the battery component 3 during monday to thursday and a corresponding increase in the number of charging cycles of the battery component 3 during friday to sundday.

The implementation method has the beneficial effects that the charging cycle times of the battery assembly in the future preset time period can be determined according to the control instruction of the user, the position of the mobile electric equipment or the use habit of the user, so that the charging plan assembly can intelligently determine the charging cycle times of the battery assembly, and the protection effect on the battery assembly is improved.

In some implementations, the charge cycle number includes a low charge cycle number, a normal charge cycle number, and a high charge cycle number.

In order to perform hierarchical control on the charging mode of the battery assembly 3 according to the number of charging cycles, the number of charging cycles may be divided into different number ranges, and further the charging mode of the battery assembly 3 may be hierarchical controlled according to the number of charging cycles.

Illustratively, the charge cycle number includes a low charge cycle number, a normal charge cycle number, and a high charge cycle number, which correspond to different charge modes of the battery assembly 3, respectively.

In some implementations, when the number of charging cycles is a low number of charging cycles, the control component 4 controls the charging component 2 to charge the battery component 3 in the low frequency operation mode.

Illustratively, when the battery assembly 3 is charged in the low frequency operation mode, the charging power of the battery assembly 3 may be reduced.

In some implementations, when the number of charging cycles is the normal number of charging cycles, the control component 4 controls the charging component 2 to charge the battery component 3 according to the normal operation mode.

For example, when the battery assembly 3 is charged in the normal operation mode, the charging power of the battery assembly 3 may be kept within a range close to the rated charging power.

In some implementations, when the number of charging cycles is a high number of charging cycles, the control component 4 controls the charging component 2 to charge the battery component 3 in the high frequency operation mode.

Illustratively, when the battery assembly 3 is charged in the high-frequency operation mode, the charging power of the battery assembly 3 may be maintained within a range greater than the rated charging power.

The beneficial effects that the realization mode brought are that, carry out hierarchical control to the charge mode of battery pack 3 according to the charge cycle number according to different quantity scope, can charge to the battery pack according to different modes respectively, improved the intelligent degree of controlling the charge power of battery pack, be convenient for carry out automated control.

In some implementations, the low charge cycle number is less than 1 charge cycle number of the battery assembly 3 in the future preset time period, the normal charge cycle number is 3 to 6 charge cycle numbers of the battery assembly 3 in the future preset time period, and the high charge cycle number is 7 to 12 charge cycle numbers of the battery assembly 3 in the future preset time period. The duration of the preset time period is 24h to 72h.

As an example, it may be determined that the low charge cycle number is less than 1 charge cycle number of the battery assembly 3 in the future preset time period, the normal charge cycle number is 3 to 4 charge cycle numbers of the battery assembly 3 in the future preset time period, and the high charge cycle number is 7 to 9 charge cycle numbers of the battery assembly 3 in the future preset time period, within the time period range of 24 hours of the preset time period.

As an example, it may be determined that the low charge cycle number is less than 1 charge cycle number of the battery assembly 3 in the future preset time period, the normal charge cycle number is 4 to 5 charge cycle numbers of the battery assembly 3 in the future preset time period, and the high charge cycle number is 9 to 10 charge cycle numbers of the battery assembly 3 in the future preset time period, within the time period of 48 hours of the preset time period.

As an example, it may be determined that the low charge cycle number is less than 1 charge cycle number of the battery assembly 3 in the future preset time period, the normal charge cycle number is 5 to 6 charge cycle numbers of the battery assembly 3 in the future preset time period, and the high charge cycle number is 10 to 12 charge cycle numbers of the battery assembly 3 in the future preset time period, within a time period of 72 hours of the preset time period.

The implementation method has the advantages that the number of charging cycles in a future preset time period can be determined, and the rationality of a charging plan of the battery assembly can be improved.

In some implementations, in the low frequency operation mode, the maximum charge amount of the battery assembly 3 is 60% -80%, the charging current is 10% -20% of the maximum charging current of the battery assembly 3, and the battery assembly 3 is charged after the electric quantity of the battery assembly 3 is reduced to 20%.

For example, in the low frequency operation mode, in order to protect the battery assembly 3 as much as possible, the maximum charge amount of the battery assembly 3 may be set to 60% to 80%, and long-term storage of the battery is suitable at 60% to 80% of the amount of electricity, thereby avoiding loss due to the overcharge of the battery assembly 3.

In the low frequency operation mode, for example, in order to protect the battery assembly 3 as much as possible, the charging current may be 10% -20% of the maximum charging current of the battery assembly 3, so as to implement trickle charging of the battery assembly 3, and at this time, the battery assembly 3 may be prevented from being excessively hot, the loss of the battery assembly 3 may be prevented, and the safety of the charging system may be also protected.

In the low-frequency operation mode, the battery assembly 3 is charged after the electric quantity of the battery assembly 3 is reduced to 20%, so that the charging times of the battery assembly 3 can be reduced, the loss of the battery assembly 3 can be reduced, the battery assembly 3 can be prevented from being damaged due to the too low electric quantity of the battery assembly 3 after the electric quantity of the battery assembly 3 is reduced to 20%, and the service life of the battery assembly 3 is prolonged.

In some implementations, in the normal operating mode, the maximum charge of the battery assembly 3 is 90% to 95%, the charging current is 80% to 100% of the maximum charging current of the battery assembly 3, and the minimum charge of the battery assembly 3 is guaranteed to be 60% of the maximum capacity of the battery assembly 3.

Illustratively, in the normal operation mode, the maximum charge amount of the battery assembly 3 is 90% -95%, and the charge amount range of the battery assembly 3 can be maintained at a high level, but the charge amount of the battery assembly 3 is maintained in a 90% -95% unfilled state, so that the service life of the battery assembly 3 can be improved.

In the normal working mode, the charging current is 60% -80% of the maximum charging current of the battery assembly 3, and the charging current of the battery assembly 3 can be limited in a reasonable range, so that the battery assembly 3 is prevented from being too high in battery temperature due to the overlarge charging current, the larger charging speed of the battery assembly 3 can be ensured, the use requirement of the battery assembly 3 in the normal working mode can be met, and the use experience of a user is improved.

In the normal operation mode, the minimum electric quantity of the battery assembly 3 is guaranteed to be 60% of the maximum capacity of the battery assembly 3, and by keeping the minimum electric quantity of the battery assembly 3 at 60% of the maximum capacity of the battery assembly 3, the battery assembly 3 can be guaranteed not to influence the use experience of the battery assembly 3 due to the fact that the electric quantity surplus is too small when the electric quantity is suddenly increased, and the use experience of a user in daily use is improved.

In some implementations, in the high frequency operation mode, the maximum charge amount of the battery assembly 3 is 95% -100%, the charging current is sequentially charged according to 80% -100%, 10% -20% and 0-10% of the maximum charging current of the battery assembly 3, and the minimum electric quantity of the battery assembly 3 is ensured to be 70% of the maximum capacity of the battery assembly 3.

Illustratively, in the high-frequency operation mode, the maximum charge amount of the battery assembly 3 is 95% -100%, and at this time, the electric quantity range of the battery assembly 3 can be maintained at a substantially full-charge level, so that the daily service life of the battery assembly 3 can be improved.

Illustratively, in the high-frequency operation mode, the charging current is charged in stages according to 80% -100%, 10% -20% and 0-10% of the maximum charging current of the battery assembly 3, and at this time, the charging can be performed in a manner that the charging current is firstly applied and then effectively applied, so that the battery assembly 3 can be prevented from being damaged due to the fact that the charging current is maintained at a high level for a long time.

In the high-frequency operation mode, the minimum electric quantity of the battery assembly 3 is 70% of the maximum capacity of the battery assembly 3, so that the battery assembly 3 can be ensured not to influence the use experience of the battery assembly 3 due to the fact that the residual electric quantity is too small when the electric quantity is suddenly increased, the time from the minimum electric quantity to the full state of the battery assembly 3 can be reduced, the influence of the insufficient residual electric quantity of the battery assembly 3 on the use experience is avoided, and the use experience of a user in daily use is improved.

In the high-frequency working mode, the minimum electric quantity of the battery assembly 3 is 70% of the maximum capacity of the battery assembly 3, so that the battery assembly 3 can be ensured to maintain a basically full-electric state when the battery assembly 3 is used frequently, the requirement of the battery assembly 3 is met, and the use experience of a user is improved.

The beneficial effects that foretell realization mode brought lie in, through the control to battery pack according to different modes according to different maximum charge, different electric currents, different minimum electric quantity charge, can satisfy the requirement of different frequency of use when improving the protection effect to battery pack, improve user's use experience.

In some implementations, the charging planning assembly 1 includes a positioning unit 11 and a receiving unit 12, where the positioning unit 11 is used to obtain a position of the wall-mounted energy storage battery, and the receiving unit 12 is used to obtain a position of the mobile electric equipment and a position change state of the mobile electric equipment.

The positioning unit 11 is used for acquiring the position of the wall-mounted energy storage battery, and the positioning unit 11 can position the wall-mounted energy storage battery through a built-in GPS module, i.e. acquire the installation and use positions of the wall-mounted energy storage battery.

Illustratively, the receiving unit 12 is configured to obtain a position of the mobile electric device and a position change state of the mobile electric device, and the receiving unit 12 may communicate with the mobile electric device through a network communication protocol, so as to obtain the position of the mobile electric device, thereby achieving monitoring of the position of the mobile electric device and the position change state of the mobile electric device.

The mobile electric equipment can be an electric automobile, and the use probability of the wall-mounted energy storage battery for the electric automobile can be predicted according to the installation position of the wall-mounted energy storage battery and the position and position change state of the electric automobile by acquiring the position of the electric automobile and the position change state of the mobile electric equipment, so that the charging plan of the battery assembly is controlled.

The wall-mounted energy storage battery charging control method has the beneficial effects that the use probability of the wall-mounted energy storage battery is predicted according to the installation position of the wall-mounted energy storage battery obtained through positioning and the position and position change state of the electric automobile, the number of charging cycles of the wall-mounted energy storage battery is determined, and then the charging schedule of the battery assembly is controlled, so that the intelligent degree of controlling the wall-mounted energy storage battery is improved.
