Some will be 22-kW units, while others will be 100 kW DC fast chargers.
Deutsche Telekom representatives revealed to German media that the company intends to build 12,000 charging stations.
The investment is expected to begin this summer, using distribution boxes that already have strong electric connections.
The plan is to double the current charging infrastructure in Germany by adding 11,500 three-phase 22 kW stations and some 500 100 kW DC fast chargers.
It would shoot Deutsche Telekom to the market leader as there are only 10,800 charging public charging stations available in Germany, although that depends on the execution, locations and pricing.
Deutsche Telekom could be tempted to join the party because plug-in car sales in Germany have lately become the highest in Europe.
