ANSI report identifies new priorities for EV battery safety and charging
The American National Standards Institute (ANSI) has released its October 2026 Gaps Progress Report, which tracks standards development for electric vehicles (EVs) in the US. The report reviews progress on 30 previously identified standardization gaps and proposes three new ones: Damaged EV battery triage, monitoring, storage, and transfer Accessible and inclusive EV charging equipment and…
How does impedance spectroscopy detect early EV battery degradation?
A battery management system (BMS) normally judges cell health from terminal voltage, current, and temperature. From these readings, capacity fade is usually estimated with a model rather than any actual measurement. However, impedance spectroscopy looks at the processes inside the cell, so it can show what is changing before the loss becomes obvious. Here, we…
EV diagnostic tools gain integrated access to OEM repair procedures
Autel U.S. has partnered with ALLDATA, an AutoZone company, to integrate original equipment manufacturer (OEM) repair information into its MaxiSYS diagnostic software. The integration connects vehicle fault codes with corresponding factory repair procedures without requiring technicians to switch between separate systems. The functionality is available on several MaxiSYS tablets, including the Ultra EV platform designed…
ZF expands electric drivetrain repair portfolio for the aftermarket
