High-voltage interlocking loop configuration structure of electric motorcycle

Abstract

The invention provides a high-voltage interlocking loop configuration structure of an electric motorcycle, which comprises a front-section frame of the electric motorcycle and a plurality of high-voltage components, the plurality of high-voltage components are intensively arranged at the front-section frame, the plurality of high-voltage components comprise a charging seat, a main battery, an on-vehicle charger and a motor controller, the main battery, the on-vehicle charger and the motor controller are respectively provided with a high-voltage interlocking loop (HVIL) connecting module and form a series loop; the plurality of high-voltage components can effectively shorten the length of a power line for connecting the plurality of high-voltage components by means of a concentrated configuration structure, so that the line loss during power transmission can be reduced, and the power utilization safety of the electric motorcycle can be ensured by means of the arrangement of the high-voltage interlocking loop (HVIL) connecting module.

Description

technical field [0001] The present invention relates to an arrangement structure of an electric motorcycle, in particular to the arrangement structure of a high-voltage interlock circuit of an electric motorcycle. Background technique [0002] Electric vehicles are vehicles that convert electrical energy into kinetic energy, and their circuit systems have high-voltage electricity of tens of volts. Therefore, in order to ensure the safety of electric vehicles, the High Voltage Interlock Loop (HVIL) technology has been widely used. for electric vehicles. [0003] For example, HVIL technology basically adopts HVIL connection module and manual maintenance switch device (Manual Service Disconnect, MSD). device, etc.) for signal series connection. In emergency rescue or maintenance, personnel can open the HVIL connection module or manual maintenance switch device to interrupt the circuit of the signals in series, which can make the electric vehicle's circuit system power off, an...

AI Technical Summary

Problems solved by technology

[0004] Vehicles that convert electrical energy into kinetic energy include electric vehicles and electric motorcycles as mentioned above. Electric motorcycles also contain a variety of high-voltage electrical components. During emergency rescue or maintenance, personnel may also encounter electric shocks, etc. The problem of unsafe electricity use

With the development of electric motorcycle technology, the safety of electric motorcycles has also received attention. When electric motorcycle manufacturers apply HVIL technology to electric motorcycles, the high-voltage components of electric motorcycles are connected by power lines. Connected to each other, the power supply also generates power loss during the transmission of the power line. Limited by the frame or body structure of traditional electric motorcycles, how to configure the positions of various high-voltage components to meet wiring and safety requirements , and reduce the power transmission loss caused by the power line, is the problem that the electric motorcycle industry needs to solve
