Mercedes-Benz develops programmable power converter for 800-V EV systems
Mercedes-Benz is developing a programmable power converter designed to manage energy flows at the individual battery-cell or cell-group level in future electric vehicles (EVs). The technology uses software-controlled micro-converters to deliver a stable high-voltage output of up to 800 V, regardless of differences in cell state of charge or ageing. Unlike conventional battery architectures, in…
ABB E-mobility and Oreve expand electric truck charging network
ABB E-mobility and French charge point operator Oreve are expanding their partnership to deploy 12 additional high-power charging sites for electric vehicles (EVs), particularly heavy-duty trucks, along major freight routes in France. The expansion will add approximately 100 charging points and 18 MW of installed capacity by the end of 2028. The companies have already…
How AI surrogate models can speed up EV battery cooling design
Cooling design has a direct effect on how an electric vehicle (EV) battery pack handles fast charging and high loads, and how long its cells last. Every change to the cell chemistry or pack layout can mean another round of thermal simulation, and some of those simulations take hours to run. Much of the information…
Lithium-metal battery testing demonstrates fast charging at 3.6C
Blue Solutions has released new fast-charging test results for its Gen4 lithium-metal battery technology, which is being developed for electric vehicles (EVs). In tests using 10 Ah nickel manganese cobalt (NMC) pouch cells, the batteries recovered 70% of their capacity in under 11.5 minutes at 40° C with a charging rate of 3.6C. At 25°…
