The future of the EV market begins with ultracapacitors
EVs are seeing market success, there are a few factors inhibiting their
widespread success. Consumers have concerns related to range and
charging. Before trading their gas cars in for EVs, they want to be sure
they will be able to charge their vehicles quickly and that those
vehicles will hold their charge for convenient lengths of time.
Ultracapacitors will lead the way in meeting these concerns and bringing
EVs to the mass market.
continues to drive improvements in energy storage technology, and
engineers are searching for ways to increase energy density in
ultracapacitors. While not currently available, researchers have a goal
of matching the energy density available in lead acid storage batteries.
When this is achieved, ultracapacitors can completely replace
batteries, and with rapid recharge rates, recharging in minutes as
opposed to hours, the technology will revolutionize the green vehicle
improvements and gains towards increased energy density begin with a
lower ESR, or equivalent series resistance. The ESR measures resistance
within the capacitor, and as the rating goes up, efficiency is lost. So,
a lower ESR means higher efficiency, which boosts the power and
improves performance. In the near future, it is likely ultracapacitors
with a decreased ESR of at least 10 percent will be available. This
would boost the power capabilities of the ultracapacitor by 10 percent
as well, and make for higher performance in applications such as micro
hybrids. Already, new generations of ultracapacitors consistently reduce
hybrids using stop/start technology require low resistance, highly
efficient ultracapacitors to perform a high number of cycles. More
energy can be delivered during the vehicle start when using an
ultracapacitor with lower resistance. Automakers can drastically improve
fuel efficiency in their vehicles with low ESR, high power
ultracapacitors because they provide a reliable technology to match the
required start/stop cycles. These ultracapacitors will free
manufacturers from the burden of excess cooling requirements and
suppressed cycle life.
durable ultracapacitor cells provide the best solution for
acceleration, energy recapture, peak load shaving and other high power
applications. And, as hybrid drive technology adoption grows, the high
power and strength help to improve ultracapacitor performance and meet
advancement and adoption in the electric vehicle industry is growing.
Engineers will continue to develop component technology in order to
extend the lifespan of such vehicles and meet consumer demands to
improve the commercial success of EVs.
