How does battery-charging without physical contact work?

I thought that you need a physical contact between the charger and the battery so the electricity actually arrives inside the battery.
Now my new electrical toothbrush seems to work differently. It has a battery, the manual confirms. It also has a charger. But all I need to do is to put the toothbrush on the charger.

How does that work? Both parts are plastic covered.
Yes, a Sonicare product.
