Abstract: A ground pad module for charging a power-driven vehicle is designed to be arranged on an underground accessible to the vehicle. The ground pad module includes a fan unit arranged within the ground pad module and configured to cool at least one electrical and/or electronic assembly arranged within the ground pad module by an air flow that can be supplied to the ground pad module from an exterior area. An inlet channel of the air flow is designed such that if the ground pad module is arranged as intended, water penetrating through an inlet opening of the inlet channel must overcome at least one step in a component of a flow direction of the water before it reaches the fan unit and/or the assembly with the component facing a direction opposite to the force of gravity.

Abstract: A method for charging an energy store in a motor vehicle by inductive energy transmission from an energy transmission unit to the motor vehicle is disclosed. The energy transmission unit can be anchored in a stationary manner on an accessible surface and is part of an inductive charging station. A communication channel is constructed between the inductive charging station and the motor vehicle for the purpose of preparing for and/or carrying out charging of the energy store. The inductive charging station provides a light signal which is to be perceived by a driver of the motor vehicle and which is not transmitted via the communication channel for signaling the readiness for charging the energy store. A charging system is also disclosed.
