[0037] First embodiment

[0038] As shown in Figures 1 to 4 The present application provides a modular energy storage emergency vehicle, which comprises:

[0039] The energy storage device 2 is designed to store electric energy and provide backup power for power consumption equipment in emergency situations; the energy storage device mainly consists of two parts: first, the container part; inside the container 2-1, a plurality of areas 2-2 for storing different electronic devices are arranged, such as Figure 2As shown, these areas are mainly separated by vertical partitions within the container; secondly, the electronic circuit part mainly includes electronic devices distributed in each area of the container and busbars arranged at the bottom of the inner cavity, and the electronic devices are connected with the busbars; in order to ensure the safety of the container, a grounding busbar 2-3 is arranged on the container.

[0040] The transport vehicle 1 is specially designed for loading and transporting energy storage devices, ensuring that these devices can be quickly and efficiently transported to emergency sites in need. In order to provide flexibility and efficiency of the transport vehicle, the transport vehicle is composed of two parts: a tractor head and a low flatbed semitrailer. The tractor head is responsible for providing power and traction, while the low flatbed semitrailer is used to carry the energy storage devices. The energy storage devices are designed in the form of containers, which are fixed on the low flatbed semitrailer in a detachable manner, making the loading and unloading process more convenient and rapid. This design not only improves the transportation efficiency, but also ensures quick response in emergency situations, thereby providing strong support for emergency rescue work.

[0041] In this embodiment: the electronic equipment mainly includes:

[0042] The energy storage battery pack is a device specially designed for storing electrical energy, which can effectively store electrical energy and provide stable power supply for various loads when needed. This battery pack usually has high energy density and long service life, which can meet the needs of different application scenarios.

[0043] The DC charger is a device that converts AC power into DC current and voltage suitable for charging the energy storage battery pack. It converts AC power into DC power and adjusts the size of current and voltage to ensure that the energy storage battery pack can be safely and efficiently charged. The DC charger usually has overcurrent, overvoltage and short circuit protection functions to ensure the safety of the charging process.

[0044] Several charging modules are responsible for converting the DC power output by the energy storage battery pack into AC power required by the load. These modules usually have high efficiency and high stability, and can adjust the output voltage and frequency according to the needs of the load. Through the cooperative work of multiple charging modules, stable power supply to the load can be realized, while improving the reliability and flexibility of the system.

[0045] The main function of the discharge module is to orderly release the electrical energy in the energy storage battery pack according to actual needs. It can control the rate and time of discharge to ensure efficient use of electrical energy. In some application scenarios, the discharge module can also realize energy recovery and reuse, further improving the overall efficiency of the system.

[0046] The power manager is a control system that manages and controls the working state of electronic devices. It can monitor the power consumption of the device in real time, optimize power distribution, and ensure that the device runs in the best state. The power manager can also achieve remote monitoring and control, provide fault diagnosis and early warning functions, and improve the reliability and maintenance efficiency of the entire system.

[0047] In order to better understand the technical solutions of the present application, the following is a non-limiting example:

[0048] The charging module can provide charging pile equipment with a variety of power ranges to meet the needs of different users.

Secondly, there are 60KW to 120KW single-gun charging piles, which are suitable for fast charging scenarios and can quickly replenish the energy of electric vehicles.

[0049] In addition, there are 30KW to 125KW 380V three-phase alternating current charging piles, which are suitable for industrial or commercial sites and can provide stable high-power output to meet the charging needs of large electric devices. Finally, there are 10KW to 50KW 220V alternating current charging piles, which are suitable for home or small commercial use, providing a safe and reliable charging solution. Whether it is for home, commercial or industrial use, this application can provide suitable charging pile equipment to meet your charging needs.

[0050] In this embodiment, some wall hangers are specially designed and arranged on the outer side wall of the container. The number of these wall hangers can be adjusted according to actual needs to meet different application scenarios. Each wall hanger has a certain load-bearing capacity and stability to ensure that the main module of the charging pile can be safely hung. In this way, the main module of the charging pile is ingeniously fixed on the outer side wall of the container, saving space and facilitating the installation and maintenance of the equipment. In addition, the design of the wall hanger can be optimized according to the size and weight of the charging pile to ensure the reliability and safety of the entire system.

These four battery packs are first connected in series and then connected in parallel to form a single cluster of 2P208S low-voltage battery system. Specifically, each battery pack contains a certain number of battery units connected in series to achieve the required voltage level. Then, the four series-connected battery packs are connected in parallel to increase the capacity of the battery system. Through this combination of series and parallel connection, a low-voltage battery system with 2P (i.e., two times in parallel) and 208S (i.e., 208 series units) configuration is finally formed. This configuration allows the energy storage battery pack to maintain a low voltage while having a high energy storage capacity, suitable for various application scenarios such as electric vehicles, energy storage power stations, etc.

[0052] Between each electronic device and the busbar, a circuit breaker is provided to ensure the safe operation of the circuit.

[0054] At the same time, a control terminal for remote data interaction with the power manager is also included. This control terminal can be a smartphone, tablet computer, or computer device, which connects to the power manager through a wireless network to achieve remote monitoring and control. Users can view the status of the power manager, data of the environmental monitoring system, and alarm information of the fire extinguishing system through the control terminal, and can also remotely control the power manager and the fire extinguishing system, improving the convenience and flexibility of operation.

[0055] Finally, a photovoltaic charging interface is provided on the DC charger. This interface can connect solar panels or other photovoltaic devices to provide power for electronic devices using solar energy. This not only protects the environment, but also provides stable power for electronic devices in the absence of commercial power supply, increasing the range and flexibility of electronic devices.

When discharging is needed, the semi-trailer will be placed at the use location, supported and leveled by the auxiliary support on the semi-trailer to ensure the stability and safety of the container. At the same time, the tractor head can leave to transport other energy storage stations, thereby improving the overall transportation efficiency.

[0058] In terms of battery system, the embodiment adopts the design of single cluster 2P208S low-voltage battery system, which can effectively reduce the cost of using end voltage reduction module. Through this optimization, the embodiment not only reduces the overall manufacturing cost, but also improves the system efficiency.

[0059] In addition, the embodiment also specially designs the bottom busbar, which helps to reduce the cost of wire harness. Through the use of the bottom busbar, the embodiment avoids the wiring error caused by too many concentrated busbar wire harnesses, thereby improving the reliability and safety of the system.
