Kempower’s charging system to support 12 satellites per Power Unit

The Finnish manufacturer has long had a decentralised satellite charging system in its portfolio: the Power Unit and the satellites with the actual charging cable can be positioned several metres apart. Most of the technology is located in the power supply units to minimise the space required at the parking space itself. The Finns are now updating the system in two ways. It will get more power and more satellites per power unit. The former will be available from the current quarter, the latter from the beginning of Q4.

The upgraded charging solution, which Kempower now presented at the Nordic EV Summit, specifically consists of a 600 or 1,200 kW Power Unit that is connected to up to twelve charging points, which increases the flexibility and scalability of power distribution. “More power and more plugs give customers greater flexibility to fit charging infrastructure to different needs, including various charging site layouts, demand profiles, and use cases,” the manufacturer explained.

We already know the 1,200 kW unit from Kempower’s megawatt charging system. In that case, however, Kempower bundled 2×600 kW power units. The satellites then have a special liquid-cooled MCS charging plug and can thus deliver a total output of 1.2 megawatts. However, Kempower now also has a system variant for the reverse case – that as many vehicles as possible should be charged in parallel with less power – with its new 12-series solution.

“Kempower has analyzed over 23,000,000 charging sessions worldwide. Based on the data, we know that when stopping, EV drivers primarily want an available plug to connect their vehicle to the charger so they can quickly take a break and continue their journey afterward,” said Jussi Vanhanen, CMO at Kempower. “By increasing the number of connectors in our satellite system from 8 to 12, we are meeting the needs of EV drivers and enhancing the efficiency of charging operators, as charging power can be distributed to vehicles more effectively.”

Update 18 June 2025

The Finnish charging station manufacturer has started deliveries of its improved satellite fast-charging solution announced in April. In the first phase, the system can dynamically distribute up to 1.2 megawatts to eight charging points – both CCS and MCS. Delivery of the system for up to twelve charging points is scheduled to follow at the beginning of the fourth quarter.

However, it will also be possible to upgrade Kempower’s existing fast-charging infrastructure in terms of both power and the number of charging points.
