The bi-directional
bonus for
EVs
Ford's 2022 F-150 Lightning can be
equipped to power a home's typical
energy needs for up to three days.
Bi-directional charging is a value-added feature that seems certain to help
accelerate EV adoption.

lthough other automakers have talked
about the potential for electric vehicles
(EVs) to use their increasingly powerful
batteries for purposes beyond propelling
the vehicle, it was Ford that brought the capability
known as bi-directional charging to prominence
when it revealed details of its new F-150 Lightning
last May. A subsequent high-visibility marketing
campaign dramatically showed the Lightning using
its bi-directional charging capability to power a sizeable
home during a power outage.
Now, just months before the Lightning hits dealer
showrooms, the outsized response to the Lightning
- Ford has twice doubled the truck's projected annual
production volume to a current 150,000 units - and
the gee-whiz nature of its Intelligent Backup Power
capability may accelerate the industry's march toward
bi-directional charging as a standard feature for most

EVs. Although there is specific hardware and software required on
both sides of the charging cable to derive the benefits of the socalled
vehicle-to-grid (V2G) capability, none of it requires a dealbreaking
investment for either OEMs or consumers. And fast-moving
innovations in onboard power electronics - particularly the vital
AC/DC inverters that are at the heart of bi-directional capability -
promise to reduce costs and broaden possibilities.
" I think every electric vehicle, eventually, will be bi-directional capable
- it's really only a matter of time, " maintained Matt Londre,
president of Willow Glen Electric and regional leader of Northern
California for Qmerit, which manages a national network of certified
electricians that help ensure EV buyers receive safe, reliable homecharging
installations. Qmerit currently collaborates with Ford, GM,
Audi, BMW, Lucid, Rivian, Volvo and Mercedes-Benz as a preferred
installer of home chargers.
" Once the F-150 Lightning comes out with it, kind of bringing the
bi-directional capabilities even more mainstream, " Londre added, " it's
going be a very large and popular thing. Almost 'table stakes.' "
