Definitions
- the invention relates to a stationary induction charging device according to the subject matter of claim 1.
- the invention particularly relates to an inductive vehicle charging system with such a stationary induction charging device.
- Inductive vehicle charging systems for charging battery-electric vehicles have stationary induction charging devices that can be arranged on a surface - such as the floor of a garage or a parking lot - which in practice are also referred to as GA (ground assembly). They are designed to interact electromagnetically with an induction charging device assigned to the battery-electric vehicle, which is referred to as VA (vehicle assembly), so that electrical energy can be transferred from the vehicle charging system to the battery-electric vehicle and vice versa.
- GA ground assembly
- VA vehicle assembly
- waste heat is generated in the stationary induction charging device, which means that there is a risk of it overheating, particularly at high ambient temperatures.
- the object of the invention is therefore to provide an improved or at least another embodiment of a stationary induction charging device and/or an improved inductive vehicle charging system for charging a battery-electric vehicle with electrical energy.
- a stationary induction charging device that can be arranged in a fixed position on a substrate for an inductive vehicle charging system designed to charge a battery-electric vehicle with electrical energy is proposed, which has at least the following
- a housing having a base plate and a cover arranged on the base plate, the base plate having a collar which projects beyond the cover and runs around it at least in sections,
- an inductive charging device which is arranged in an interior of the housing delimited by the base plate and the cover in thermal contact with the base plate and is designed for electromagnetic interaction with an induction charging device assigned to the battery-electric vehicle, so that electrical energy can be transferred from the stationary induction charging device to the battery-electric vehicle and vice versa, and
- a cooling device which is designed to convectively dissipate heat from the base plate to the ambient air surrounding the stationary induction charging device and is in thermal contact with the collar.
- the stationary induction charging device During operation of the stationary induction charging device, losses occur in the form of heat, particularly at the inductive charging device, which is mainly introduced into the base plate and from there dissipated convectively to the ambient air on the one hand and by heat conduction to the subsurface on the other. a relatively effective temperature control of the stationary induction charging device can already be achieved.
- the achievable dissipable heat per unit of time, i.e. the cooling capacity is however proportional to the temperature difference between the base plate on the one hand and the ambient air and the subsurface on the other.
- the transmission power of the stationary induction charging device is currently throttled when a predetermined transmission power is called up from the stationary induction charging device and a certain ambient temperature is reached or exceeded. This means that less heat is lost in the stationary induction charging device, so that overheating can be avoided with the given heat that can be dissipated per unit of time.
