Kempower boosts the electrification of heavy-duty vehicles by launching liquid-cooled satellite charger
7.6.2022 09:00:00 EEST | Kempower Oyj | Press release

The decarbonization of the heavy-duty transport sector is crucial if the world is to achieve its net-zero aspirations. Trucks, buses and coaches are currently responsible for around 25% of CO2 emissions from road transport in the European Union and approximately 6% of the region’s total emissions. In the United States, medium and heavy-duty trucks account for about 29% of road transport’s total emissions – and approximately 7% of the country’s total – despite being less than 5% of the total vehicles on the road. Moreover, while the pace of electrifying heavy-duty vehicles is increasing, emissions are continuing to rise, primarily due to the growing amount of freight traffic on roads.
The new charger model looks similar to Kempower’s existing S-Series charging satellite system, with the liquid-cooled cables replacing the traditional air-cooled cables. It also features the same user interface and experience as the company’s current satellite charger, which has received positive feedback from drivers for being intuitive and simple to use.
Providing 400kW of continuous power means that the liquid-cooled satellite charger will enable vehicles to be charged more quickly by delivering higher power. This improvement will help overcome one of the last remaining barriers to the electrification of heavy-duty transport.
“We drew upon the Kemppi Group’s 70 years of welding heritage and expertise in cooling welding cables during the development of this product, guaranteeing high levels of safety and quality. Our customers can install liquid and air-cooled fast charging satellites in separate charging systems or combine both products into the same system, optimizing investment costs while dynamically allocating unused power to different charging satellites. Our technology also makes it possible to prioritize the liquid-cooled charging satellites to always receive full power, dynamically redistributing power when other satellites are being used,” commented Tomi Ristimäki, Kempower’s CEO.
“We believe that electric will be the winning technology for heavy-duty vehicles in the long run. This product launch is the latest example of how we’re supporting its development,” Ristimäki adds.
Kempower will showcase the Kempower S-Series liquid-cooled charging satellite system at EVS35, the world’s largest EV event, between June 11th-15th in Oslo, Norway. The product will subsequently be available globally, with deliveries expected to begin in the third quarter of 2022.

Kempower ChargEye data shows more charging plugs drive higher public charging site utilization in North America25.8.2026 16:00:00 EEST | Press release
New Kempower white paper analyzes real-world data from Kempower ChargEye-connected public charging sites across North America.
Kempowerin datan mukaan latauspisteiden määrän lisääminen kasvattaa julkisen latausaseman käyttöastetta25.8.2026 16:00:00 EEST | Tiedote
Kempower on julkaissut uuden raportin, jossa analysoidaan yhtiön ChargEye -latauksenhallintajärjestelmään liitetyistä julkisista latausasemista eri puolilta Pohjois-Amerikkaa saatavaa dataa. Tulokset osoittavat, että latauspisteiden lukumäärällä on huomattavasti vahvempi yhteys latausaseman käyttöasteeseen kuin aseman lataustehon kokonaismäärällä. ChargEye on Kempowerin pilvipohjainen sähköajoneuvojen latauksenhallintajärjestelmä, jolla latausoperaattorit voivat ohjata ja optimoida latauslaitteiston ja ajoneuvojen lataamista. Raportissa tarkastellaan, miten latausaseman suunnittelu voi vaikuttaa käyttöasteeseen, jaettuun tehoon ja aseman pitkän aikavälin kannattavuuteen. ChargEyen data osoittaa, että latauspisteiden lukumäärällä on noin kolme kertaa suurempi vaikutus aseman käyttöasteeseen kuin asennetulla latausteholla. ”Julkisessa lataamisessa infrastruktuurin käyttöaste on yhä tärkeämpi kysymys tehonjaon rinnalla,” sanoo Kempowerin Pohjois-Amerikan markkinoista ja tuotteista vastaav

Denverin julkiset koulut ja Winn-Marion ottavat käyttöön Kempowerin latausratkaisut kasvavalle sähköbussikalustolle Yhdysvalloissa19.8.2026 10:00:00 EEST | Tiedote
Yhdysvalloissa Coloradon osavaltiossa Denverin julkiset koulut ovat saaneet käyttöönsä uutta Kempowerin latausinfrastruktuuria piirin kasvavan sähköbussikaluston tarpeisiin Hilltopin bussiterminaaliin. Kempower toimi teollisuuden automaatio- ja sähköratkaisujen toimittaja Winn-Marionin johtamassa hankkeessa laitteistotoimittajana ja teknologiakumppanina. Koulupiiri hankki äskettäin 25 uutta Blue Bird Vision -sähköbussia kasvattaen sähköbussikalustonsa 28:aan, mikä on piirin mukaan Coloradon suurin. Uusi latausinfrastruktuuri on valmiina uuden lukuvuoden alkaessa 24. elokuuta. ”Koulubussikannan sähköistämiseen tarvitaan latausinfrastruktuuria, joka toimii päivittäisten kuljetusaikataulujen vaatimusten mukaisesti”, sanoo Kempowerin Pohjois-Amerikan toimitusjohtaja Monil Malhotra. ”Kempowerin teknologia pitää sähköiset koulubussit ladattuina, käyttövalmiina ja liikenteessä, jotta Denverin julkiset koulut voivat tarjota oppilaille päivittäin luotettavia ja vähäpäästöisiä kuljetuksia.” Buss
The first Kempower Mega Satellite Flex in Sweden will be delivered to Dagab’s depot in collaboration with Erinion18.8.2026 10:00:00 EEST | Press release
The first Swedish delivery of the new Kempower Mega Satellite Flex charging solution will take place at Dagab’s depot in Bålsta in August, with commissioning scheduled for the autumn. Dagab is responsible for the Axfood Group’s supply chain and manages the entire logistics chain from warehousing to transport. The solution is being supplied, commissioned and monitored by Erinion, Kempower’s end-to-end partner for charging infrastructure for heavy-duty fleets and part of the Scania Group. Dagab currently has nearly 40 electric trucks in operation, 13 of which are based at the logistics centre in Bålsta. To meet the growing charging demand, a Kempower Mega Satellite Flex is now being installed, capable of charging both today’s CCS-equipped trucks and next-generation MCS vehicles from the same charging unit. This provides a flexible and future-proof solution as the vehicle fleet continues to be electrified. The platform builds on Kempower’s distributed charging architecture and is being in
