[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0026] like Figure 1 The embodiment of the present invention is a split portable power supply device, including a battery 110, a base 120, a power assist system 130 and a power management system 140. The modular battery 110 and the base 120 are split designs, and the battery 110 is not fixed inside the device.

[0027] like Figure 2 As shown, the battery is used to store electric energy, and the number of the batteries is 3. Each battery is provided with a battery connector and a battery protection circuit board, and the battery connector has a power pin, a communication pin, a scene pin and a position pin for separate charging and discharging. The battery has a unique ID code; and the battery connector is electrically connected to the protection circuit board.

[0028] like Figure 3 As shown, the base 120 is provided with a battery slot, a plurality of power input interfaces 122, a plurality of power output interfaces 123, a color LCD screen display module 124, a lighting lamp 125 for lighting and sending a distress signal, and a pull rod 126 for easy movement. A base connector 121 is provided at the bottom of the battery slot.

[0029] like Figure 4 As shown, the mobility assist system 130 includes a wheel hub motor 131 , a driver 132 , and a start button 133 .

[0030] like Figure 5 As shown, the power management system 140 includes a photovoltaic module 141 , a communication module 142 , an inverter module 143 and a logic control module 144 .

[0031] In a specific implementation, when the battery 110 is inserted into the battery slot of the base 120, the battery connector 111 is combined with the base connector 121. Figure 6 As shown, the battery detects whether the battery is in a multi-battery scenario through the level signal of the scene identification pin 7 on the base connector 121. If the scene identification pin is grounded (connected to its own pin 11), it is a multi-battery scenario, otherwise it is a single-battery scenario. In a multi-battery scenario, the battery can only open the charge / discharge port through the instruction of the power management system 140. The battery can also detect the physical position of the battery in this power supply device through the level signal combination of the address identification pins 8 / 9 / 10 on the base connector 121. The relationship between the address and the level signal combination is shown in the following table.

[0032]

[0033] When we need to move the device, we slide the start button 133 on the pull rod 126, such as Figure 4 As shown. The power assist system 130 is activated, and there are 3 speeds adjustable. The wheel hub motor 131 rotates under the control of the driver 132 to provide power assist for the mobile device.

Select the corresponding socket connection according to the needs of the power-consuming device. If it is an AC power-consuming device, the power of the battery 110 enters the inverter module 143 of the power management system 140 through the discharge port, and then enters the power-consuming device through the 5-hole or 3-hole socket of the AC output interface to power the device. If it is a DC power-consuming device, the power of the battery 110 enters the transformer module 145 of the power management system 140 through the discharge port, and then enters the power-consuming device through the DC output interface to power the device.

[0035] When the battery needs to be charged, we plug the external power cord into the power input interface 122 of the base 120. This power supply device provides an AC power input interface 220V three-pin socket. The AC power supply can be a mains power grid or a diesel generator; there is a DC power input interface XT60, and the DC power supply can be solar discharge or vehicle discharge. Select the corresponding socket connection according to the type of external power supply. If it is AC power, it enters the inverter module 143 of the power management system 140 through the AC input interface, and then enters the charging port of the battery 110 to charge the battery. If it is DC power, it enters the photovoltaic module 141 of the power management system 140 through the DC input interface, and then enters the charging port of the battery 110 to charge the battery.

[0036] The communication module 142 of the power management system 140 is connected to each device in the power supply device through a communication circuit, obtains the status information of the battery 110 and the power assist system 130 in real time, receives instructions from each device, and sends instructions to control the actions of each device through the logical judgment of the logic control module 142 to complete the above-mentioned charging and discharging power management.

[0037] In this embodiment, the number of batteries is 3.

[0038] In this embodiment, the connector has 3 power pins, 3 communication pins, 1 scene pin, and 4 location identification pins.

[0039] In this embodiment, the power-assisting system is a driver driving two wheel hub motors.

[0040] In this embodiment, the communication module includes one or more of RS485, CAN, Bluetooth, and WIFI.

[0041] In this embodiment, the input interface includes a DC input interface and an AC input interface. The DC input interface is used to connect solar power generation and vehicle power supply; the AC input port is used to connect to the mains and diesel generator.

[0042] In this embodiment, the output interface includes USB-A, USB-C, cigarette lighter port, 5521 port, and XT60 port, and can supply power to electronic devices having the above interfaces.

[0043] In this embodiment, the output interface also includes a 5-hole socket and a 3-hole socket of AC220V, which can supply power to electrical equipment with the above interfaces.

[0044] In this embodiment, the power output interface also includes a wireless charging module.

[0045] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work.
