Kempower and Polarium to boost  
DC fast charging solutions with cutting-edge energy storage support

Polarium, a leading energy storage developer, and Kempower, a pioneering company specializing in rapid DC charging solutions, are proud to announce a partnership to boost EV fast charging solutions with cutting-edge energy storage support. This collaboration aims to address the pressing need for enhanced EV charging capabilities, particularly for larger vehicles, constrained by current grid limitations across Europe. 

With the rapid rise in the number of electric vehicles, the demand for efficient charging solutions has never been more urgent. However, existing grid constraints pose significant challenges to meet this demand. This partnership aims to bridge this gap by integrating Polarium Battery Energy Storage Systems (BESS) with Kempower’s charging solutions, providing reliable and sustainable power distribution while minimizing peak loads and optimizing energy consumption. 

Through Polarium’s cutting-edge energy storage technology, Kempower’s chargers will be empowered to accommodate multiple electric vehicles seamlessly without requiring costly grid upgrades. This ensures faster charging times of more and larger vehicles, such as trucks and public transportation, while maintaining equal power distribution across all units, preventing peak loads that result in higher demand charges. 

“Partnering with Kempower aligns perfectly with Polarium’s mission to unlock endless energy. By merging our expertise in BESS with Kempower’s innovative charging infrastructure, we’re positioned to overcome Europe’s grid limitations. Through this collaboration, we’re integrating cutting-edge energy storage solutions into EV charging infrastructure, ensuring Kempower’s customers receives optimal charging experiences.” says Håkan Tezcanli, Key Account Manager at Polarium. 

“No matter the route or distance, power supply is key when making DC fast charging a reality, especially for trucks. With Polarium’s support, we can ensure that our charging infrastructure meets current and future energy demands, supporting the roll-out of EVs as constant connectivity is crucial for everything to run smoothly. In simple terms, without energy storage support, the grids are not strong enough to handle the high-power charging needs.” Says Jussi Vanhanen, Chief Market Officer at Kempower. 

This collaboration marks a significant step towards creating the world’s most desired EV fast charging solutions, positioned to transform transportation across Europe. 

Kempower and Polarium will be showcasing their latest innovations at KEY – The Energy Transition Expo, taking place from February 28th to March 1st, 2024, in Rimini, Italy.
