Abstract
A modular vehicle system is provided, comprising an electric vehicle, particularly a light electric vehicle, with at least a control device; an on-board power supply system for energy supply of an electric drive unit; an interface, connected to the on-board power supply system for connection of at least one module; and first locking means arranged at the interface. The modular vehicle system further comprising a module, with a module control, configured to communicate with the control device; an electric arrangement;
a connecting element, separably connectable to the interface, for connection of the electric arrangement with the on-board power supply system; and second locking means arranged at the connecting element, formed for engagement with the first locking means, wherein at least one of the locking means is movable between a free position and a locking position. To increase the safety of operating the system, the module control is configured to send an identification signal to the control device upon connection of the connecting element to the interface; and the control device is configured to receive the identification signal, to compare the identification signal with at least one compatibility parameter, and in case that the identification signal corresponds to the compatibility parameter, to send an activation signal to at least one switch unit to connect the electric arrangement with the on-board power supply system.
