[0001] The utility model relates to the technical field of vehicle energy, in particular to a vehicle-mounted integrated power supply module. Background Art

[0002] Conventional vehicle-mounted power modules only have a small-power generator for power generation and only one starting battery. The vehicle's power, energy, and power supply and distribution voltage platform are insufficient and single. After the vehicle is turned off, the lack of electricity limits the use of load equipment. When it is necessary to expand equipment applications, there are great limitations. In addition, without an energy management module, effective management of power supply and distribution cannot be achieved, resulting in poor energy utilization. Utility Model Content

[0003] The main technical problem to be solved by the present invention is to provide an on-vehicle integrated power supply module, which solves the problem that the vehicle's power, energy and power supply and distribution voltage platform are insufficient and single, and after the vehicle is turned off, the use of load equipment is restricted due to insufficient power. When the equipment application needs to be expanded, there are great limitations, and there is no energy management module, which makes it impossible to achieve effective management of power supply and distribution, resulting in poor energy utilization.

[0006] The DC-AC bidirectional conversion module is connected to the AC load to supply AC energy to the load equipment; the energy management module is connected to the storage battery pack, the DC-AC bidirectional conversion module and the DC-DC bidirectional conversion module respectively.

[0007] In a preferred embodiment: the reserve battery pack is also bidirectionally connected to a DC source, and the DC source is also connected to the energy management module. The DC source receives a charging communication instruction or a discharging communication instruction from the energy management module to charge the reserve battery pack or absorb the electrical energy of the reserve battery pack and convert it into power to assist the vehicle.

[0008] In a preferred embodiment: the DC-AC bidirectional conversion module is also connected to an AC source for accessing mains power or alternating current, and the AC source is also connected to the energy management module.

[0015] In order to make the technical solutions and features of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0016] Example 1

[0017] refer to Figure 1To solve the practical problems of insufficient energy storage and power limitation, this embodiment provides an on-vehicle integrated power supply module, including a DC-AC bidirectional conversion module, a reserve battery pack, a starting battery unit, and a DC-DC bidirectional conversion module.

[0018] The reserve battery pack is configured based on actual energy and power requirements and is bidirectionally connected to a DC-DC bidirectional conversion module and a DC-AC bidirectional conversion module. The DC-DC bidirectional conversion module interfaces with a DC high-voltage load and a starter battery unit, respectively. The starter battery unit can also feed excess power back to the reserve battery pack via the DC-DC bidirectional conversion module.

[0019] To address the issue of a single power source, the reserve battery pack is also connected to a DC power source to charge the reserve battery pack, enabling slow or fast charging. The DC-AC bidirectional conversion module is also connected to an AC power source to access mains power or alternating current. After the AC source is connected to the on-board integrated power module, it charges the reserve battery pack, enabling slow or fast charging.

[0020] To address the issue of a single power distribution platform, the DC-DC bidirectional conversion module interfaces with the DC high-voltage load and the starting battery unit, outputting power at different DC voltage platforms, such as air conditioners, fresh air blowers, lights, and lifts. The DC-AC bidirectional conversion module interfaces with AC loads to supply AC energy to any load devices, such as induction cookers and kettles.

[0021] The starting battery unit is connected to a DC low-voltage load to provide electrical energy thereto. The DC low-voltage load is usually an original vehicle load, such as a starter, a lamp, a fan, a lift, etc.

[0022] This embodiment can supply sufficient electrical energy to the on-board electrical equipment after the vehicle is turned off, thereby expanding the availability of the vehicle load equipment.

[0023] This embodiment also includes an energy management module. The DC source, AC source, reserve battery pack, DC-AC bidirectional conversion module, and DC-DC bidirectional conversion module interface with the energy management module. By collecting and transmitting communication signals, the module coordinates charging and discharging based on the energy supply and demand within and outside the on-board integrated power module. Specifically, after the DC source is connected to the on-board integrated power module, it receives charging or discharging communication instructions from the energy management module to charge the reserve battery pack or absorb electrical energy from the reserve battery pack and convert it into power to assist the vehicle. As a key component of the mild hybrid architecture, this module, combined with energy management control strategies, optimizes the original vehicle power system. The AC source also interfaces with the energy management module. After the AC source is connected to the on-board integrated power module, it receives charging communication instructions from the energy management module to charge the reserve battery pack. The DC high-voltage load also interfaces with the energy management module. After the DC high-voltage load is connected to the output terminal of the on-board integrated power module, it receives communication instructions from the energy management module to allow discharge, provides real-time feedback on its operating status, and dynamically adjusts its output to achieve optimal and stable operating performance.

[0024] By setting up an energy management module, after each power supply and distribution equipment or load equipment is connected, the communication data of the connected equipment is collected, and combined with the energy management control strategy, control instructions are sent for charging and discharging. This process is real-time and controllable. The application of the energy management module realizes the efficient use of energy and maximizes the reduction of energy consumption and vehicle use costs. The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
