[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figure 1 As shown, this utility model embodiment provides a mobile energy storage and charging integrated circuit, including an energy storage system and a charger system. The energy storage system includes a battery pack (BAT) and a DC socket (DCCZ), and the charger system includes an AC socket (ACCZ), a charging module (VF), a main control board (PCBA), and an AC-DC voltage conversion module.

[0024] The AC socket ACCZ is electrically connected to the input terminal of the charging module VF through the circuit breaker QF1, and the output terminal of the charging module VF is electrically connected to the charging gun CDQ; the output terminal of the circuit breaker QF1 also converts the AC power into DC power through the AC-DC voltage conversion module to power the main control board PCBA.

[0025] The DC socket DCCZ is connected to the input terminal of the battery pack BAT, and the output terminal of the battery pack BAT is electrically connected to the input terminal of the charging module VF through the circuit breaker QF2; the battery pack BAT also supplies power to the main control board PCBA after current conversion through the DC-DC voltage conversion module.

[0026] The main control board (PCBA) is primarily used to integrate the microprocessor and control circuitry, coordinating the operation of various modules, including:

[0027] Controls the input / output mode switching of the charging module: AC input / DC input / energy storage discharge;

[0028] Receives data from the detection board and executes protection logic for overcurrent, overvoltage, and overheat protection;

[0029] It supports the OCPP protocol and local / remote control, enabling card-swipe startup, password startup, and access to the operation platform.

[0030] When AC380V±10% voltage is input to the AC socket ACCZ terminal, circuit breaker QF1 is turned on. The AC socket ACCZ outputs voltage through circuit breaker QF1 to the charging module VF, which outputs 150V-1000V DC voltage. Then, the charging gun CDQ charges the new energy vehicle or replenishes the battery pack BAT. At the same time, the AC-DC module supplies power to the main control board PCBA and other equipment (such as the electricity meter PJ, detection board JCB, router RD1, pile-end communication conversion module SECC, and vehicle-end communication conversion module EVCC, etc.).

[0031] In the absence of AC power, an external charging pile or external power source can input DC500V-750V voltage through the DC socket DCCZ to directly charge the battery pack BAT. The battery pack BAT sends its voltage and current requirements via CAN communication. At the same time, QF10 and QF3 conduct to output voltage to the DC-DC voltage conversion module to power the main control board PCBA and other devices (such as the electricity meter PJ, detection board JCB, router RD1, pile-end communication conversion module SECC, and vehicle-end communication conversion module EVCC, etc.).

[0032] When neither AC nor DC power can be provided, i.e. there is no input and power is needed, circuit breaker QF2 is turned on. The battery pack BAT outputs voltage through circuit breaker QF2 to the charging module VF, which outputs 150V-1000V DC voltage to charge new energy vehicles. At the same time, QF10 and QF3 are turned on to output voltage to the DC-DC voltage conversion module to power the main control board PCBA and other devices.

[0033] This invention enables charging of new energy vehicles or replenishment of battery packs (BAT) via circuit breaker QF1 and AC power supply system when only AC power is available; and replenishment of battery packs (BAT) via DC power input DC charging socket DCCZ when only DC power is available. In outdoor situations where neither AC nor DC power is available, new energy vehicles can be charged via battery packs (BAT) within the energy storage system. This achieves dual-input charging function (AC and DC) and dual-mode replenishment capability, effectively overcoming the limitations of existing equipment and significantly improving its compatibility and flexibility of use.

[0034] This utility model supports adaptive adjustment of charging power, with a maximum output current ≥200A. Furthermore, through the design of AC-DC voltage conversion module and DC-DC voltage conversion module, this utility model achieves dual-loop control power supply function: AC220V is converted to 12V through AC-DC module, and DC500V-750V is converted to 12V through DC-DC module, forming a redundant control power supply.

[0035] Meanwhile, circuit breakers QF1 and QF2 can be combined into an interlocking device. The hardware interlock between circuit breakers QF1 and QF2 ensures that the AC input and DC input do not close at the same time, thus preventing circuit conflicts.

[0036] Specifically, such as Figure 1 As shown, on the battery pack BAT, CHARG is the energy storage charging port, DISCHARGE is the main energy storage discharging port, and DC is the auxiliary power discharging port for the battery pack BAT. When the system is cold, the auxiliary power discharging port of the battery pack BAT has a voltage output used as the control power for the entire system. COM1-7 / 8 are the control power supplied to the BAT from the charging system. When the system is low on power, the external AC220V is output as DC12V through AC-DC to provide control power to the battery pack BAT.

[0037] In this embodiment, the output terminal of the charging module VF is electrically connected to the charging gun CDQ through the fuse FU1 and the shunt TS1. The fuse FU1 is used for hardware overcurrent protection of the output, and the shunt TS1 is used for output current monitoring and measurement.

[0038] Furthermore, such as Figure 1 As shown, a surge protection device (SPD) is also configured between the AC socket ACCZ and the circuit breaker QF1. The surge protection device SPD is used for lightning protection and high voltage protection. How the surge protection device SPD is connected in the circuit between the AC socket ACCZ and the circuit breaker QF1 is prior art, and will not be described in detail here.

[0039] Furthermore, circuit breakers QF10 and QF3 are connected in series between the battery pack BAT output terminal and the DC-DC voltage conversion module. Circuit breaker QF3 is the switch for both the DC-DC module and the battery pack BAT, while circuit breaker QF10 is the main control power switch from the BAT, used for precise control of the battery BAT output. How the circuit breakers control the switching and power output is existing technology and will not be elaborated further in this embodiment.

[0040] In addition, the charging system also includes an electricity meter PJ, which is used to measure the output electricity of the charging pile.

[0041] Preferably, the charger system also includes a detection board JCB. The detection board JCB is mainly used to integrate sensors and detection circuits for real-time monitoring of current, voltage, and temperature in the circuit, in order to monitor abnormalities in the circuit in real time.

[0042] Furthermore, the charging system also includes a router RD1, which has LAN, 4G, and WIFI network functions to achieve wireless communication, remote monitoring of equipment status, and data uploading to the operation platform, so that users can view it from a mobile client.

[0043] in addition, Figure 1 The SECC module in the charging station is the charging pile communication conversion module, converting Chinese standard (GB) to European standard (EC) and Chinese standard (GA) to American standard (US). The EVCC module is the vehicle-side communication conversion module, converting European standard (EC) to Chinese standard (GB) and American standard (GA) to Chinese standard (GB). Communication protocols for GB, EC, GA, and Japanese standards are configured in the program, and can be selected individually or in combination as needed. Therefore, the CDQ charging gun supports GB, EC, GA, and Japanese charging interfaces, with an output voltage of 150V-1000V, and is compatible with protocols such as CCS and CHAdeMO.

[0044] It is understood that the specific model selection of the electricity meter PJ, detection board JCB, router RD1, main control board PCBA, pile-end communication conversion module SECC, and vehicle-end communication conversion module EVCC is a conventional choice for those skilled in the art. For example, the model of the electricity meter PJ is MAX-JSY-MK-229, the model of the detection board JCB is MAX-CP02538, the model of the router RD1 is AR350, the model of the main control board PCBA is MAX-CP01589, the model of the communication conversion module SECC is KM-SECC, and the model of the communication conversion module EVCC is KM-EVCC-002. However, the embodiments of the present invention are not limited to the above models. Those skilled in the art can of course choose other models of electricity meter PJ, detection board JCB, router RD1, main control board PCBA, pile-end communication conversion module SECC, and vehicle-end communication conversion module EVCC. Since these are conventional choices for those skilled in the art, this embodiment will not elaborate further or limit them here.

[0045] In summary, this utility model provides a mobile energy storage and charging integrated circuit with AC / DC dual input / output functions, including an energy storage system and a charging system. When only AC power is available, the circuit breaker QF1 charges the new energy vehicle through the AC power supply system; when only DC power is available, the circuit breaker QF2 charges the new energy vehicle through the DC power supply system; and in outdoor conditions, the new energy vehicle can be charged through the battery pack BAT within the energy storage system. This achieves AC and DC dual input charging functions and dual-mode power replenishment capabilities, effectively overcoming the limitations of existing equipment and significantly improving its compatibility and flexibility of use.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment have been appropriately combined to form other embodiments that are easy for those skilled in the art to understand.
