German energy storage system developer Tesvolt has signed a strategtic invested deal with a company developing technology wireless charging for electric vehicles as they drive along.
The deal with Stercom Power Solutions aims to accelerate inductive wireless charging of electric cars, buses and lorries up to 200kW. Test routes with magnetic coils under the asphalt are already in place in Sweden, Isrel, Italy and France and BMW has predicted blanket coverage of inductive charging by 2030
“Our aim is to work together to bring highly efficient charging systems to the market and even in the medium term to enable inductive supercharging with up to 200 kW charging power. This would also make it more efficient to charge while driving in the future,” said Simon Schandert, founder and Chief Technical Officer at Tesvolt.
Tesvolt specialises in developing energy storage systems based around prismatic lithium battery cells from Samsung SDI combined with a patented and TÜV-certified Active Battery Optimizer (ABO) smart cell control system. The system are built series at a gigafactory in Wittenberg.

Wireless charging involves transferring electrical energy in an inductive process from a magnetic coil in or on the floor to a receiver coil in the electric vehicle. This allows for many short but high-speed charging processes – for example on shopping centre forecourts, in multi-storey car parks as well as at home. Car makers like Audi and BMW are already installing charging coils in new vehicle models.
Having inductive charging via the road would allow smaller battery packs in a vehicle, reducing the weight ad boosting efficiency without having range anxiety.
“So far the only wireless charging suitable for mass-production has just 3.2 kW. We want to introduce an inductive charging station to the market with a charging power of 44
