Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicles, and in particular relates to an intelligent charging system and a charging method for a two-wheeled electric motorcycle. Background Art

[0002] As a new energy vehicle, electric two-wheeled motorcycles (two-wheeled electric motorcycles) are environmentally friendly, convenient, and efficient. From the perspective of user experience, the static power consumption of the entire vehicle has gradually become a focus of their attention. In addition to outputting high power to power the motor and DCDC (DC-DC converter), high-speed two-wheeled electric motorcycles also need to focus on protecting the battery to ensure that its continuous power supply is not affected.

[0003] The battery of a two-wheeled electric motorcycle has a small capacity and therefore needs to be recharged frequently. When the two-wheeled electric motorcycle is in a dormant or long-term consignment state, the stored energy of the battery will be consumed.

[0004] At present, the two-wheeled vehicle industry rarely involves the battery replenishment strategy of two-wheeled electric motorcycles. For electrical components that need to maintain power, the main treatment methods in the two-wheeled vehicle industry can be summarized as follows:

[0005] (1) Mainstream electric two-wheelers based on the 72V platform usually use a key switch to maintain power, and the driver can completely control the power on and off by cutting off the voltage source. This system can only be operated manually, and remote operation cannot be achieved, which limits the operation;

[0006] (2) A few smart electric motorcycles choose to use DCDC, using the battery pack (drive battery pack) that comes with the two-wheeled vehicle to convert its internal 72V voltage into 12V voltage to provide a stable power supply for some electrical components. Although this method can achieve remote operation and maintain the power of electrical components, the continuous use of the battery pack will reduce the range of the electric two-wheeled vehicle to a certain extent, reduce the number of times the battery pack is charged and discharged, greatly reduce the service life of the battery pack, and increase safety risks. Summary of the invention

[0007] In order to solve the problems in the prior art that the capacity of the battery used to maintain the power of the electrical components of the electric two-wheeled vehicle is small, the battery pack is continuously used to power the battery, which reduces the cruising range, reduces the number of charge and discharge times of the battery pack, greatly reduces the service life of the battery pack, and increases safety hazards, the present invention provides a two-wheeled electric motorcycle intelligent power replenishment system and power replenishment method. The purpose is to overcome the shortcomings of the prior art and to provide a technical solution that uses a small-capacity battery to maintain the power of the electrical components that need to be maintained, and can realize the ability to independently replenish the small-capacity battery.

[0069] In order to facilitate remote control of the power replenishment operation, in this embodiment, the power replenishment system also includes a cabin-driver integrated domain controller CDDC and a service platform TSP. The cabin-driver integrated domain controller CDDC is equipped with a terminal TBOX. The vehicle controller GCU, the cabin-driver integrated domain controller CDDC and the service platform TSP are connected by signals in sequence.

The terminal TBOX can assist the low-voltage controller LPDC in intelligent power replenishment. In the vehicle sealing mode, the user can remotely perform the power replenishment operation through the APP, and the power replenishment operation is more convenient and user-friendly.

[0070] like Figure 1 and Figure 2 As shown, a two-wheel electric motorcycle intelligent power replenishment method, the power replenishment method uses the above-mentioned two-wheel electric motorcycle intelligent power replenishment system, and the power replenishment method includes the following steps:
