Lion Smart to study fast charging truck batteries
The feasibility study has been commissioned by an unnamed ‘premium OEM’, and is intended to enable significantly shorter charging times for electric HGVs. With the vast majority of electric trucks requiring overnight charging, such a battery system could greatly reduce the need for additional chargers in truck depots.
LION states that the concept under development focuses on an immersion-cooled high-performance battery featuring an integrated battery management system with both single-cell monitoring and electrochemical impedance spectroscopy (EIS). The firm says this combination will effectively enable analysis of battery condition in real time and deliver efficient thermal management – something that it believes will ultimately be necessary to the 15-minute charging goal.
LION’s immersion cooling technology underwent a number of successful tests last year, with the 400V LION Smart battery ‘significantly’ exceeding test parameters and performance requirements under stress conditions. In July 2024, a German vehicle manufacturer carried out track tests with a prototype of the ‘Lion Light’ battery. Vehicles with battery voltages of 400 and 800 volts performed ’30 per cent above the current market standard’, according to reports.
Regarding the feasibility study, LION E-Mobility CEO Joachim Damasky said: “This order is a clear signal of confidence in our technological expertise in the field of immersion-cooled battery systems. Our technology is designed for industrial applications with high requirements. The collaboration shows that our approach is perceived as a future-proof solution for heavy-duty electric transportation.”
