Car-charging network ChargePoint announced that it would buy General Electric’s electric vehicle (EV) charging stations today for an undisclosed amount of money. ChargePoint also announced a $43 million investment, led by Siemens, which will be used to improve European infrastructure for EVs.

The purchase of the GE stations will add close to 10,000 charging stations to ChargePoint's network, with 1,800 commercial charging stations and 8,000 residential. GE’s charging hardware and software won’t be changed, but ChargePoint said in a press release that existing GE station customers and owners would be able to “take advantage of smart features such as access control, pricing capabilities, and software solutions like energy management and scheduled charging.” Drivers who previously used GE charging stations can now track their usage and search for ChargePoint stations through the company’s mobile app.

The latest $43 million investment in the company with money from Siemens closed out a $125 million funding round (Daimler was the other largest investor in this round). Siemens supplies ChargePoint with direct-current charging components. Ralf Christian, CEO of the Siemens Energy Management Division, will join the ChargePoint board of directors.

ChargePoint is the largest operator of an EV charging network in the world, supporting more than 36,000 independently owned charging spots. Last year, the company completed a pair of charging corridors from Boston to Washington, DC and from Portland, Oregon to San Diego. Charging stations were spaced 75 miles apart.

In Europe, policy is set to push automotive buyers toward more EV purchases. Just last November, BMW, Volkswagen Group, Ford, and Daimler agreed to build nearly 400 “ultra-fast” charging points along European roads based on the Combined Charging System (CCS) standard. The network is set to be completed in 2020.

As of last year, there were just two million EVs on the road around the world. But that number is expected to increase quickly, potentially even to nine million or more by 2020.
