Description

Technical Field

[0001] This application relates to the field of charger technology, and in particular to a charging conversion efficiency enhancement system. Background Technology

[0002] Electric bicycles and electric tricycles are widely used in the market. As the range of electric vehicles increases, the capacity of their lithium batteries also increases, leading to longer charging times. Currently, electric vehicle lithium batteries are charged using a single charger. If customers want faster charging, they must replace the charger with one that has a higher charging current, resulting in low flexibility. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides a charging conversion efficiency enhancement system, comprising at least two charger modules, a conversion system, and at least two power output terminals. The conversion system includes an MCU module, a relay module, and a first communication module. Each charger module includes a second communication module and a power output module, which are communicatively connected. The MCU module is controllably connected to the relay module. The power output module of each charger module is connected to each power output terminal via the relay module, and any power output terminal is connected to a battery pack.

[0004] Preferably, the relay module includes switches S1, S2, S3 and S4. The power output modules of the two charger modules are respectively connected to one of the power output terminals through switches S1 and S3, and the power output modules of the two charger modules are respectively connected to the other power output terminal through switches S2 and S4.

[0005] Preferably, the charger module further includes a 12V power supply module, which is electrically connected to the MCU module and the relay module respectively.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

[0012] Example

[0013] To address the aforementioned technical problems, this embodiment provides a charging conversion efficiency enhancement system, such as... Figure 1As shown, the system includes at least two charger modules, a conversion system, and at least two power output terminals. The conversion system includes an MCU module, a relay module, and a first communication module. Each charger module includes a second communication module and a power output module. The second communication module and the first communication module are communicatively connected. The MCU module is controllably connected to the relay module. The power output module of each charger module is connected to each power output terminal via the relay module. Each power output terminal is connected to a battery pack. When a battery pack is connected to one of the power output terminals, the MCU module controls the relay module to switch on and off, causing the relay module to conduct to both charger modules simultaneously. This allows both charger modules to charge the battery pack simultaneously, achieving fast charging. This system enhances the charger's flexibility and improves charging efficiency.

[0014] Specifically, this embodiment uses two charger modules and two power output terminals as an example. The relay module includes switches S1, S2, S3, and S4. Each switch is connected to the current output terminal of the charger module. The power output modules of the two charger modules are connected to one of the power output terminals via switches S1 and S3, and to the other power output terminal via switches S2 and S4. When the MCU module detects that a battery pack is connected to one of the power output terminals, it sends an electrical signal to the relay module, thereby opening switches S1 and S3 and closing switches S2 and S4. Communication is then established through the first and second communication modules, enabling both chargers to charge the battery pack simultaneously, thus achieving fast charging and improving charging efficiency.

[0015] Furthermore, when both power output terminals are connected to the battery packs, switches S1 and S4 are turned on, while switches S2 and S3 are turned off, allowing the two chargers to charge the two battery packs respectively. Once one battery pack is fully charged, the switches can be used to connect the output terminals of the two chargers to the partially charged battery pack, thus quickly charging that battery pack, increasing charging efficiency and improving flexibility.

[0016] Furthermore, the charger module also includes a 12V power supply module, which is electrically connected to both the MCU module and the relay module, thereby providing power to both modules. Simultaneously, the conversion system also includes a voltage regulator module, which is connected to both the MCU module and the relay module. For example, the voltage regulator module uses voltage-regulating components such as Zener diodes. The specific circuit structure of the voltage regulator module can utilize commercially available voltage regulator circuits to achieve voltage regulation. Furthermore, the 12V power supply module, power output module, and communication module in the charger module can also use existing common circuit structures that achieve 12V power supply, communication, and current output. This embodiment does not impose limitations or elaborate further. The focus of this solution is on the module composition of the conversion system and the connection structure between each module and the charger module. The MCU module controls the relay module to switch on and off according to actual operating conditions, thereby enabling multiple chargers to charge a single battery pack, achieving increased efficiency.

[0017] Furthermore, the conversion system also includes a 4G communication module that communicates with the MCU module and with the mobile terminal. A 12V power supply module is electrically connected to the 4G communication module. The charger body module's second communication module is connected to the MCU module, which in turn connects to the 4G communication module. The 4G communication module then connects to mobile terminals such as smartphones. This allows users to monitor the charging status in real time via their mobile terminals, or control the charger to turn charging on or off, improving the convenience of charging operations.

[0018] In summary, this application's solution incorporates multiple charger modules, a conversion system, and multiple power output terminals. The conversion system includes an MCU module, a relay module, and a first communication module. Each charger module includes a second communication module and a power output module, which are communicatively connected. The MCU module is controllably connected to the relay module. Each charger module's power output module is connected to each power output terminal via the relay module, and any power output terminal is connected to a battery pack. When a battery pack is connected to one of the power output terminals, the MCU module controls the relay module to switch on and off, enabling the relay module to conduct to two charger modules simultaneously. This allows both charger modules to charge the battery pack simultaneously, achieving rapid charging. This efficiency-enhancing system improves the charger's charging flexibility and increases charging efficiency.

[0019] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
