FIG 2 Number of EV charging stations around the globe
in 2022. Data from [4].
800 V vehicles coming soon [12]. Outside of China,
companies such as Audi, Hyundai, Porsche, and Kia
recently announced 800 V vehicles, with Lucid
announcing a 900 V vehicle [13]. The ramp to 800 V
may be slow though-while innovation may be happening,
one analyst predicts that from a market point
of view, by 2025 only 12% of EVs on the road will be
800 V capable [14].
On the other hand, Tesla executives have gone on
record saying that they don't see sufficient value to
going towards 800 V vehicles [15], which likely means
that superchargers will remain at 500 V for the near
future. Thus, while all the standards allow >750 V
maximum voltage, the majority of charging ports
available may only be 500 V. This situation demonstrates
how the exact implementation of the standard,
not the standard itself, determines the power
semiconductor required.
In conclusion, we return to the question posed at
the beginning of the column-what will be the
impact on WBG semiconductor trends? The divide
between 800 and 400 V vehicles and chargers points
to a potential semiconductor differentiation. If the
predominant voltage remains in the 500 V and below
range, GaN is obviously an option. This situation is
now more likely as consumer EV and charging station
suppliers coalesce around Tesla. For 750 V+
chargers, a multi-level topology would be required
for GaN, and thus SiC might continue to be favored.
Both voltages enable different tradeoffs in charging
time, efficiency, and costs. Recent proposals for
hybrid solutions with IGBT may make for the best
cost-efficiency trade-off, but the equation is very different
due to differences in cost and voltage/current
capabilities between GaN and SiC [16], [17].
