[0034] Among them, the charge and discharge module 11 refers to a module responsible for managing and controlling the charging process of the battery by the solar panel and the discharging process of the battery to the electrical equipment, and usually includes an MPPT (maximum power point tracking) controller of the solar panel and a charge and discharge manager of the battery, etc.; the aviation plug refers to a connector between the solar panel and the multi-output controllable solar controller, and between the multi-output controllable solar controller and the battery; the solar panel is a device that converts solar energy into electrical energy; the battery refers to a device used to store the electrical energy generated by the solar panel during the day so as to supply power to the electrical equipment at night or on cloudy days, etc.

[0035] The multi-channel control module 12 is connected to the battery, and the multi-channel control module 12 is also respectively connected to multiple controlled devices.

[0036] Among them, the multi-channel control module 12 refers to a module that controls multiple output channels; the controlled device refers to an electrical equipment that performs power management and control through the multi-output controllable solar controller, such as Figure 1 the control main board, sound column, radar, and router shown in

[0037] The multi - output control module 12 includes a power acquisition unit capable of obtaining the current battery power of the storage battery, a signal output unit for outputting corresponding control signals according to the current battery power, and a control unit for controlling the start - stop state of the multiple controlled devices based on the control signals.

[0038] Among them, the power acquisition unit can adopt a power acquisition chip with the model of Maxim Integrated MAX17043. The current battery power represents the electric energy currently stored in the storage battery, usually expressed as a percentage or a specific power value.

[0044] Please refer to Figure 2 , Figure 2 which is the schematic structural diagram of the multi-output control module 12 provided by the embodiment of the present utility model.

[0045] The multi-output control module 12 includes:

[0046] A DC converter (not shown), the DC converter is connected to the battery, and the DC converter is also connected to the data transmission unit and the control unit.

[0047] Among them, the DC converter is a DC-DC converter, which is used to convert the original DC voltage output by the battery into the working voltage of the controlled device.

[0049] Among them, the preset DC voltage represents the working voltage of the controlled device.

[0050] For example: Figure 2 As shown, the DC converter receives the 24V DC voltage output by the battery, and the working voltage of the controlled devices (control main board, sound column, radar, router) is 12V DC voltage. Therefore, the DC converter converts the 24V DC voltage into 12V DC voltage to supply the controlled devices.

[0063] Among them, the switch state represents the current working state of the relay, which can be a closed state or an open state.

[0064] Specifically, the relay can switch the state of the contact according to the received control signal to realize the on-off control of the circuit. When the contact of the relay switches to the closed state, the controlled device is powered, so it is in the on state. When the contact of the relay switches to the open state, the controlled device has no power supply, so it is in the off state.

[0065] The power supply adaptation module includes:

[0066] An inverter adapter, the inverter adapter is connected to the storage battery, and the inverter adapter is also connected to the device to be adapted through an aviation plug.

[0067] Among them, the inverter adapter is a DC-AC converter, which is used to convert the original DC voltage output by the storage battery into the working voltage of the device to be adapted.

[0076] The signal output unit includes:

[0077] A main control chip U2, which is respectively connected to the power acquisition unit and the data transmission unit, and the main control chip U2 is also respectively connected to the multiple relays.

[0078] Wherein, the main control chip U2, namely the STM32F103RCT6 chip, refers to the central processing chip of the multi-output control module 12. The power acquisition unit is connected to the storage battery to obtain the current battery power. This chip receives the current battery power sent by the power acquisition unit, and then outputs multiple control signals according to the current battery power and the preset control logic to control the start and stop states of the multiple controlled devices.

[0079] Please refer to Figure 4 , Figure 4 which is a schematic diagram of a control logic provided by an embodiment of the present application.

[0080] Specifically, whether to turn on the power supply is controlled according to the current battery power. When the current battery power is greater than Q1, the power supply is turned on, and when the current battery power is less than Q2, the power supply is turned off.

[0081] When the main control chip U2 receives the current battery power, it outputs multiple control signals to the multiple relays respectively according to the current battery power to control the start and stop states of the multiple controlled devices; the main control chip can also receive the autonomous control data sent by the cloud platform through the data transmission unit, and output autonomous control signals to the multiple relays according to the autonomous control data to control the start and stop states of the multiple controlled devices.

[0082] Among them, the autonomous control data represents the data for controlling the start and stop states of each controlled device sent by the user through a remote location (such as an application program of a smart phone), and the autonomous control signal is a signal output by the main control chip according to the autonomous control data for controlling the start and stop states of the controlled devices, which is a specific and executable instruction that can directly control the working state of the relay, thereby affecting the running state of the controlled device.

[0083] Specifically, the power acquisition unit obtains the battery voltage multiple times, removes the singular values (voltage fluctuations caused by the start and stop of loads such as motors), takes the average value, measures the battery voltage after taking the average value according to the working environment temperature, obtains the current battery power by looking up the look-up table, and sends the current battery power to the main control chip U2. The main control chip U2 outputs multiple control signals according to the current battery power. Please refer to Figure 5 , Figure 5 FIG. is a schematic diagram of a look-up table provided by an embodiment of the present application. This look-up table takes a lithium iron phosphate battery as an example and is made according to the measured data (capacity values corresponding to different voltages under different temperature conditions measured under the condition of 0.33C discharge). After finding the current battery power, the current battery power is corrected according to the battery parameters. For example, for a 12v60Ah lithium iron phosphate battery with an internal resistance of 120 milliohms, when the current is 1A, the supply voltage drops by δv = 0.12 * 1 = 0.12v due to the internal resistance, and when the current is 3A, the supply voltage drops by δv = 0.12 * 3 = 0.36v due to the internal resistance. The corrected voltage is the sum of the battery voltage and the supply voltage drop value. The capacity value corresponding to the corrected voltage is found in the look-up table and used as the corrected current battery power.
