Description

Technical Field

[0001] This utility model relates to a power supply and distribution system that integrates power generation and lithium battery energy storage, belonging to the category of power generation and distribution systems. Background Technology

[0002] With the diversification of energy demands and increasing environmental protection requirements, power supply and distribution systems are gradually developing towards high efficiency, flexibility, and low carbon emissions. Traditional power supply and distribution solutions rely on fixed power grids or diesel generator sets, which have significant limitations in mobile platforms and remote areas. A fixed power grid refers to the power supply and distribution system connected to a fixed power grid, which is then rectified and inverted before being supplied to electrical equipment. In remote areas, there is no fixed power grid to connect to. Diesel generator sets generate electricity by igniting an engine to drive a generator rotor. While diesel generator sets can solve the power problems of mobile platforms and remote areas, they suffer from high noise and pollution, and can only output power at rated capacity, unable to adjust output power according to the actual needs of the electrical equipment, resulting in low energy utilization.

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] Example 1

[0022] like Figure 1 The power generation and lithium battery energy storage integrated power supply and distribution system shown includes a main control unit, which is connected to control the power generation unit and the lithium battery energy storage unit respectively. The power generation unit is connected to the lithium battery energy storage unit through a regulated AC power link, and the lithium battery energy storage unit is connected to the power distribution unit through a regulated DC power link. The output terminals of the power distribution unit are connected to output 600V DC voltage and 24V DC voltage respectively.

[0023] Generally, based on the selection of readily available products in the existing technology, the power take-off unit can collect information such as output voltage, output current and remaining fuel in real time, and send the above information to the main control unit.

[0024] Example 2

[0025] Based on Example 1, a voltage regulator chip with a standard voltage of 380V is present on the regulated AC power link. Therefore, the power take-off unit can convert chemical energy into mechanical energy via an engine, and then convert the mechanical energy into electrical energy via a generator for output. The output electrical energy voltage is AC380V, and the frequency is 50Hz.

[0026] Furthermore, there is a voltage regulator chip with a standard voltage of 600V on the regulated DC power line.

[0027] Furthermore, the main control unit uses CAN bus communication to connect and control the power take-off unit and the lithium battery energy storage unit.

[0028] Furthermore, CAN bus communication uses the CAN2.0B protocol.

[0029] Example 3

[0030] Based on Embodiment 1, the lithium battery energy storage unit includes a lithium battery pack and a BMS module. The BMS module is connected to control the lithium battery pack. The power take-off unit and the power distribution unit are both connected to the lithium battery pack, and the main control unit is connected to the BMS module. The lithium battery energy storage unit is equipped with a power management system and a lithium battery pack, which can manage and control the storage and output of electrical energy by the lithium battery pack.

[0031] Furthermore, the main control unit includes a DSP chip, operation buttons, and a display screen.

[0032] Furthermore, the main control unit connects to control the on / off state of the power distribution unit via direct connection to control relays and contactors.

[0033] Furthermore, the power take-off unit is connected to the charging port of the lithium battery energy storage unit.

[0034] Generally, the connection method of the power distribution unit is as follows: Figure 5 As shown, the built-in switching power supply module can convert DC600V power to DC24V power, and can connect and disconnect the DC600V and DC24V power outputs under the control of the main control unit.

[0035] Therefore, the control buttons can control the main control unit to issue control commands. The main control unit can control the lithium battery energy storage unit to start or stop outputting DC600V power, and the main control unit can control the power take-off unit to start or stop outputting AC380V power. The main control unit can also control the lithium battery energy storage to use the AC380V power from the power take-off unit for charging. The main control unit collects the output voltage, output current, and remaining power of the lithium battery energy storage unit, as well as information about the power take-off unit, and displays it on the screen. Based on the remaining power of the lithium battery energy storage unit and the remaining fuel in the power take-off unit, it automatically starts or stops the power take-off unit, extending the system's power supply time under the same fuel supply conditions. The power distribution unit can convert the DC600V power output from the lithium battery energy storage unit to DC24V power, and simultaneously connect or disconnect the system's external DC600V and DC24V power supplies under the control of the main control unit.
