EnBW puts new DC test system from ZERA into operation
Together, Netze BW and EnBW are preparing for the future challenges in DC metrology and electromobility. Particularly in the case of fast charging stations, a significantly higher power can be delivered to the e-vehicle using direct current. The advantage is essentially shorter charging times.
Charging stations are subject to calibration law
With the amendment of the Mess- und Eichgesetz – MessEG (German Measurement and Calibration Regulation) in 2015, it was determined that charging stations for e-mobility are subject to calibration law.
In determining values for energy (kWh) or for the time elapsed during the charging process, only conformity-assessed or calibrated charging stations* may be used in commercial transactions (§ 31 Para. 1 page 1 MessEG). This serves to ensure consumption-based billing for the customer and provides confidence.
As the operator of the largest fast charging network in Germany, EnBW is also driving forward the expansion of ultramodern HPC (High Power Charging) charging locations throughout Germany. With a charging capacity of up to 300 kilowatts, e-cars can charge up to 100 kilometres of new range there within five minutes. The company already operates more than 700 fast-charging locations of its own and will more than triple this to 2,500 by 2025. One new location is added every day on average, where you can charge your e-car.

More than 700 own fast-charging locations
With a charging capacity of up to 300 kilowatts, e-vehicles can be charged to get 100 kilometres of new range within five minutes. The company already operates more than 700 fast-charging locations of its own and will more than triple this to 2,500 by 2025. One new location is added every day on average, where you can charge your e-vehicle.
Increasing demand for DC test technology
Due to the strong roll-out of the DC charging infrastructure and the ambitious plans for the further expansion of EnBW’s fast charging network for electromobility, there is an increasing need to take a closer look at DC measuring technology.
Since March 2022, the new DC meter test system from ZERA has been in operation at EnBW’stest laboratory. With this new testing technology, EnBW will further expand their expertise in the area of DC measurement. Initially, the facility will be used to cover internal tasks. First test services are now also offered to external customers.

Our stationary solutions for testing DC meters
Our new, stationary DC test systems combine DC amplifiers with digital measurement technology from the STM6000 series. They provide the performance of all measurement tasks as well as as well as the data communication. A DC-capable reference meter with connected DC transducer ensures the high measurement accuracy. DUTs up to 600 A and 1000 V can be calibrated or tested.
A comprehensive overview including all safety components is available on our product pages.
Our mobile solutions for testing EV charging stations
Our test cases of the EMOB series allow measuring currents of up to 32 A (AC) and 200 A (DC). By using our battery-operated reference meter of the s2 series and the software-guided test sequence via notebook, testing of charging stations, wallboxes etc. is as comfortable and as simple as it gets.
