Whether your inductive charging system is to be to the specification of a standard, or you wish to set all parameters yourself, INTIS will adapt and optimise its inductive charging technology to the requirements of your particular application.
We have the ability to rapidly and effectively complete development cycles due to the systems integration expertise of our highly experienced engineers, coupled with INTIS’ own extensive prototyping and testing facilities.
Using inductive charging
We can carry out retrofits of most vehicles. Here is an overview of the interface possibilities and requirements.

Advantages and Features of Inductive Charging
The vision of inductive technology is that we don’t have to think about charging …
Vehicles can be used to move people or goods and the energy they need to perform is just there, automatically and with no effort required. Inductive energy transfer technology is an enabler of the autonomous electric transport system of tomorrow.
Inductive energy transfer technology is advantageous for applications where:

Example scenario – CEP logistics centre
A CEP company wishes to electrify its delivery fleet in order to reduce costs and improve their environmental credentials. The vehicles’ battery capacity is enough to cover the daily delivery route, so charging happens overnight at their logistics centre. The inductive charging technology is hidden and out of the way, so personnel can walk all round the vehicles to load them. Once the drivers are ready, the vehicles can just be driven away with no further action required. In the evening, the vehicles are simply parked and start charging automatically.
Example scenario – electric ferry
Small vehicle and passenger ferries are used to cross a canal at various points. Currently they are operated using diesel engines, which run the whole day. However, the ferries only have a short crossing time and spend most of the day docked waiting for or loading passengers and vehicles.
Electric ferries outfitted with inductive charging technology charge automatically while the ferry is being loaded and unloaded. Because the ferry in this application spends a relatively long time docked, compared to the crossing time, the battery can be charged gently. This increases battery life and further reduced the lifecycle cost of the total system. Because there are no moving parts, the inductive charging system does not suffer from wear and tear. No personnel is required for connecting to the charging infrastructure.
