Energy & Power battery solutions for heavy vehicles

Full day operations or opportunity charging

Scalable modular system

Liquid thermal management

Forsee Power’s FLEX battery modules are intended for heavy electric or hybrid vehicles that can be charged either occasionally or overnight at the depot thanks to the high power / energy ratio.

Integrating a liquid thermal management system, advanced electronics and NMC cells with proven technology, FLEX battery modules benefit from a high level of reliability and safety, thus ensuring a full warranty for manufacturers.

Forsee Power electrifies maintenance locomotives

Since 2020, we supply the railway manufacturer Socofer, selected by Getlink (formerly Eurotunnel) to equip 19 maintenance locomotives. It integrates the Forsee Power FLEX 7 batteries already proven in many Transport projects (buses, industrial vehicles, boats), composed of NMC type lithium-ion technologies combining energy and power. The goal is to replace the current diesel locomotives with a 100% electric solution.

The mission of Socofer and Forsee Power meets a precise specification, on three rolling equipment in charge of the maintenance of terrestrial and submarine infrastructures: the cleaning trains, the catenary trains and the PRD trains – for the maintenance of the pressure relief duct.

Wrightbus’ StreetAir EV bus runs 18-hour service with FLEX 7

Since 2013, Forsee Power has been the battery partner of Wrightbus when it comes 100%-electric bus applications. Wrightbus equips its StreetAir EV buses with robustness batteries, which require an outstanding lifespan, and was concerned about the recharge rate. Forsee Power recommended its FLEX 7 battery systems with no need to charge the battery during the whole day and with over 10 years of lifespan .

The performance of this 300 kWh battery solution on-board – 6 string of 7 battery modules per bus –  makes it easy for the 10.6-meter-long single deck to cover up to 200 miles before charging is required.
