Device for recharging batteries of electric vehicles for goods transport and travel

Abstract

The invention relates to a device for recharging batteries of electric vehicles for the transport of goods and travel, in particular long-distance trucks, coaches, vans and motorhomes. In order to make goods transport and travel more climate-friendly, the invention proposes that island overhead lines be provided above the driving route in order to recharge the batteries of the electric vehicles by direct power feed-in during the journey. This is a major step towards improving the climate, as it makes electric vehicles suitable for transporting goods and for long-distance travel. With such a solution, electric vehicles can travel thousands of kilometers without needing to recharge.

Description

[0001] The invention relates to a device for recharging batteries of electric vehicles for the transport of goods and travel, in particular long-distance trucks, coaches, vans and motorhomes.

[0002] The transport sector contributes approximately 20% to climate change, a threat to us all. Trucks, coaches, vans, and motorhomes travel thousands of kilometers on fossil fuels without refueling. Electric trucks, coaches, vans, and motorhomes have limited battery capacity due to their weight. They can only cover a fraction of the distance of their fossil fuel-powered counterparts without recharging their batteries. The number of charging stations in Europe is relatively small. Furthermore, the vehicle must leave the road or highway, necessitating a longer stop to recharge its battery.

[0003] European freight transport using vehicles powered by fossil fuels is clearly partly responsible for 1. The hot and long periods of the year result in many heat-related deaths and crop failures, 2. The devastating, horrific floods that destroyed European infrastructure and resulted in many deaths, 3. Severe storms destroying European infrastructure, resulting in many deaths.

[0004] The purpose of the invention is to make the transport of goods and travel more climate-friendly.

[0005] This problem is solved within the scope of the invention by providing island overhead lines above the driving route to recharge the batteries of electric vehicles by direct power feed-in while driving. This is a major step towards climate improvement, as it makes electric vehicles suitable for transporting goods and for long-distance travel. With such a solution, electric vehicles can travel thousands of kilometers without a charging stop.

[0006] The most effective and therefore highest efficiency can be achieved by directly feeding power into the grid while driving under the island overhead lines. The traction battery then does not need to have such a large storage capacity and can therefore be smaller and lighter. In addition, the lifespan of the traction battery is increased, resulting in a significant cost advantage. The traction battery is not discharged under the island overhead lines, but rather recharged. By far the greatest cost reduction is achieved by eliminating charging times at charging stations.

[0007] The solution according to the invention is advantageous insofar as the roads with island overhead lines are drivable for electric vehicles and all other road users with road approval.

[0008] A further development of the invention consists in the length of the island overhead lines corresponding to the average charging time of the battery of the electric vehicles.

[0009] Furthermore, it is part of the invention that the distances between the island overhead lines correspond to the average driving time of the electric vehicles until recharging.

[0010] The spacing of the island overhead lines on the roads is calculated based on the average travel time of electric vehicles until recharging. In mountainous areas, this reduces the travel time between two island overhead lines.

[0011] The island overhead lines can be supplied with energy by regional power providers, preferably generated by wind power, photovoltaics, or biomass power plants, and potentially stored temporarily in energy storage systems. Naturally, the same voltage should be present everywhere, for example, 380 V three-phase current. To limit the voltage drop across the island overhead lines, a certain length of these lines should not be exceeded.

[0012] It is conceivable that when driving under the island's overhead power lines, the vehicles will operate in autopilot mode (lane keeping assist, distance keeping assist, steering assist, etc.) to allow the drivers a break.

[0013] Island overhead lines should preferably not be located in the area of ​​entrances and exits, toll bridges, overpasses and tunnels.

[0014] To overtake slow or defective vehicles in areas with island overhead lines and prevent congestion, it is advantageous for electric vehicles to have a dedicated overtaking autopilot. When activated, this autopilot lowers the pantograph and switches from direct power feed-in to battery operation. After overtaking, the autopilot automatically raises the pantograph again and switches the motor back from battery operation to direct power feed-in.

[0015] The detection and access to the island overhead lines is preferably achieved using AI or GPS. Upon reaching the island overhead line, the electric vehicle's pantograph raises and the vehicle's drive motor switches from battery operation to direct drive. During this process, the electric vehicle's data is recorded for subsequent electricity billing. At the end of the island overhead line, the electric vehicle's pantograph lowers again and the drive motor switches from direct drive to battery operation. The electric vehicle's electricity consumption is then transmitted to the electricity provider.

[0016] The amount of electricity consumed by the electric vehicle is recorded in this way and billed to the vehicle owner.
