Electric Vehicle Batteries
Enter a New Era

T

he first feature article of this
issue of IEEE Power Electronics Magazine, "Electric Vehicle Batteries Eye Solid-State Technology," is by yours truly and investigates the developments in solid-state
batteries for electric vehicles (EVs)
and hybrid EVs and what is driving
them. Besides offering lower cost,
lighter weight, higher energy density,
and greater range, the solid-state version, with solid electrodes and electrolytes, is also expected to provide a
higher degree of safety.
In essence, based on data from
the market research firm Yole Développement, the article shows that
to commercialize solid-state batteries, four different types of technology players are joining forces to share
knowledge and overcome challenges.
Plus, the article identifies key automotive original equipment manufacturers (OEMs) that have made substantial
investments in companies developing
solid-state batteries.
In the next article, "A Novel Current-Balancing Method for Paralleled
MOSFETs in High-Current Solid-State
Switch Applications" by Alinaghi Marzoughi and K haled Bahei-Eldin, a
novel method to parallel individual
power semiconductor devices in solidstate switch applications is proposed.
The authors believe that this method
can also be extended to any other low/
