News Charging your car wirelessly? A reality for Volvo

For the next three years, the main taxi operator in Gothenburg, Sweden, will use a small fleet of 100% electric Volvo XC40 Recharge models. Revolution, these cars will be recharged using wireless technology!

Evaluate new solutions

“The goal is simple, it’s about experimenting with promising new technologies in real conditions. After evaluation, they could be deployed in the future.” says Volvo. The charging stations used are delivered by Momentum Dynamics, one of the specialists in wireless charging systems. But how does this technology work?

How it works ?

Charging begins automatically when a compatible vehicle parks above a dedicated parking space. A charging plate integrated in the street allows the vehicle to be charged without having to handle a terminal, plug in a charger or get out of the car. The charging plate sends energy to a receiver unit placed in the vehicle. Volvo specifies that its 360° camera system makes it possible to perfectly align the vehicle with the device.

The vehicles used are taxis

How fast can this system charge the car?

For this Volvo XC40 Recharge model, the wireless charging power is more than 40 kW. The charging speed is thus four times faster than an 11 kW wired AC charger and almost as fast as a 50 kW wired DC fast charging system. As part of the experimentation of this fleet of taxis, the vehicles will be used for more than twelve hours a day and will travel 100,000 km per year. This charging test will also be a durability test for these 100% electric models for commercial use.

A future solution?

Even though wireless charging is still in the experimental stage, the technology works. Equipping parking spaces could make it easier for users to charge their electric car. In the meantime, there is no system that is compatible with all batteries or cars. A solution that could become the solution if all stakeholders define a common standard.
