Siemens is pooling development and production of converters for hybrid and electric vehicles at a new international headquarters in Erlangen, Germany.

The German power technology group said it is adding 1,300 square meters of space for inspection and testing to a 1,200 square meter manufacturing plant for converters. The combination of the two functions will let it respond faster to automotive customer demand, Siemens said.

Joerg Grotendorst, CEO of Siemens eCar Powertrain Systems, said the company wants to send "a clear signal" to the market for electromobility.

"In combination with our motor production in Bad Neustadt, we are now in a position to equip tens of thousands of vehicles a year with our innovative electric powertrains," he said in a press release.

Sales of electrically powered vehicles have lagged behind the official goals set by various governments, despite strong sales growth by individual car brands. Nissan and Renault have already sold more than 200,000 EVs and the brands' CEO, Carlos Ghosn, continues to predict a healthy future for them. Specialist electric sports car maker Tesla is also posting continued strong sales growth.

In Germany, the government is sticking to a goal of having 1 million EVs on the roads by 2020. That is despite lackluster sales and relatively low numbers so far. According to official records, registrations of pure EVs in Germany dropped to 8,522 in 2014 from 12,156 in 2013. Registrations of hybrids fell to 27,435 from 85,575 a year earlier.

In the US, the government has already conceded that its 1 million EV target for this year will take a few more years to be realized. Less than 300,000 EVs and plug-in hybrids have so far been sold.
