16 The push for e-powertrain progress
COVER STORY
Upstarts and heavy-hitter suppliers alike are fast-tracking advances in
existing e-propulsion technology - as well as radical new solutions.
21 Battle for the box BATTERY PACK TRENDS
EV battery enclosures are a hotbed of subsystem design, materials
innovation and vehicle integration.
25 Returning to the SAE presidency
for 2023 PEOPLE
Boeing veteran Todd Zarfos brings a " prudently aggressive "
mindset to help advance SAE's goals in the mobility ecosystem.
26 Balancing the 'dominos' in EV
thermal management THERMAL MANAGEMENT
Excessive internal valve leakage is an inefficiency that worsens
upstream system inefficiencies. Effective valve design is the solution.
28 Deep breathing for EV batteries
BATTERY VENTING
Optimum venting is a key to maximizing EV battery pack performance
and safety. An expert offers five important design considerations.
ON THE COVER
New innovations in e-propulsion tech are the focus of this month's
cover story. A new generation of e-motors include externally-excited
machines, novel internal cooling, PCB stators with etched copper
conductors and much more. The rundown begins on page 16.
