Northvolt secures partnership with Umicore and BMW

Northvolt has secured a partnership with Belgian chemicals company Umicore and German carmaker BMW to design and commercialize a process that would give automotive lithium-ion batteries a second life as an energy storage system, before recycling them. BMW will provide expertise in battery cell development and Umicore in developing battery active materials and recycling. BMW …

Ny gruppe under DBS Groups: Genanvendelse af Litium batterier

EU anslår, at der på tværs af Europa indsamles blot omkring 10% af de litium batterier, som indføres til eller produceres i EU. I Danmark estimeres det, at omkring 50% at de litium batterier, som sælges i produkter, ikke indsamles på trods af klare regler om producentens eller sælgers ansvar for korrekt bortskaffelse. Den manglende genindvindelse …

Low-complexity online estimation for LiFePO4 battery state of charge in electric vehicles

This paper proposes a low-complexity online state of charge estimation method for LiFePO4 battery in electrical vehicles. The proposed method is able to achieve accurate state of charge with less computational efforts in comparison with the nonlinear Kalman filters, and also can provide state of health information for battery management system. According to the error …

Lithium batteries – fire and safety hazards

Due to the use of certain chemical compounds in combination with high energy densities and the use of control electronics (potential of technical defect) required for secondary batteries, lithium batteries are associated with specific potential hazards which need to be taken into special consideration with regard to safety. Spectacular incidents have raised public awareness of …
