he electric vehicle (EV)
market globally is growing
fast, and stunning growth
is projected to continue
through 2040 and beyond.
While it's the kind of
growth that reflects strong customer enthusiasm,
manufacturers recognize that
for most drivers, purchasing an EV is a
fundamental shift that may hinge on
their concerns about the vehicle's range
and reliability.
At the upper limit, EVs can travel 350plus
miles on a single battery charge,
creating real cause for excitement in the
automotive industry - but also a nagging
source of range anxiety for drivers.
The fear that a driver will run out of
battery power while on the road, without
access to a charging station when they
need it, is real.
In fact, range anxiety is credited as a
leading factor in why consumers are not
gravitating toward EVs as quickly as automotive
manufacturers had projected.
Some potential EV owners also have
concerns regarding the safety and reliability
of EV batteries, which have been
amplified by media stories of EV fires.
Battery lifetime is another issue for consumers,
with fears of batteries needing to
be replaced within a few years, at huge
expense (Figure 1).
How can EV manufacturers effectively
overcome the most common fears of
drivers?
The semiconductor automated test
equipment (ATE) sector can help. To meet
this challenge, EV manufacturers must
first embrace the critical role of battery
management systems (BMS) and then demand
the generation of highly accurate
battery data for existing and future EVs.
By enabling more accurate cell-by-cell
monitoring - a significant advance in overall
EV battery monitoring - the ATE industry
can drive improvements in the verification
of the monitoring accuracy that's essential
for continued growth of the EV industry.
Increasing range, extending battery
life, and ensuring the safety and reliability
of lithium-ion (Li-ion) batteries
are the three key technical challenges
that automotive systems engineers can
