The world of transportation is undergoing a massive shift from gas and diesel-powered cars, trucks, ships and planes to ones powered by electricity. The shift is being necessitated by the need to eliminate harmful climate changing greenhouses gases. The transportation sector in the US emits the largest amount of greenhouse gases (28%), and its transition to alternative fuels is imperative to the slowing of catastrophic climate change.


Dynapower is at the heart of this transition to e-mobility (electro mobility) with its power electronics and battery energy storage systems.

E-mobility is a blanket term for the process of using electric powered technologies for transportation as opposed to relying on gasoline and fossil fuels. E-mobility uses external charging from electrical power sources such as the grid and renewables.

E-mobility is comprised of fully electric vehicles, driverless cars, hydrogen fueled vehicles, hybrids and plug-in hybrids. Basically, any mobile vehicle that moves via electricity falls under the umbrella of e-mobility.

Falling battery prices and breakthroughs in energy storage have accelerated electrification of transportation. Numerous car manufacturers from Volvo to GM have announced their fleets transitioning to 100% electric in the next two decades or less.

Simply having electric vehicles is not enough. The effectiveness of emission-free or emission-reduced driving is influenced by the energy source used to power the vehicles. For instance, energy harvested from wind and solar or even green hydrogen (read more about that here) can make EV vehicles more impactful than ones fueled by electricity derived from fossil fuel burning resources such as coal and natural gas plants.

Dynapower’s Role in the E-mobility Movement

Here at Dynapower, we’re proud to play a part in the story of e-mobility—specifically in the area of battery energy storage. Essentially, Dynapower in conjunction with its partners, designs and builds energy storage systems that help power EV charging stations used to facilitate e-mobility across the globe with safe and reliable electric fueling.


With storage-enabled EV charging becoming more widely adopted as a means of avoiding transmission upgrades and lowering costs to rapidly deploy charging, Dynapower has a variety of energy solutions that are built around reliability, safety and efficiency.

“In many cases, the grid can’t support the amount of energy that goes into EV chargers and upgrades to the grid would be too expensive so it’s less costly to use batteries,” said Dynapower’s E-Mobility Segment Leader Richard Morin. “Also being able to lower utility demand charges makes battery energy storage very attractive for making the economics work for installing EV charging stations.”

Dynapower equipment is built for EV charging applications anywhere from 250kW projects all the way up to 5 and 10MW projects. We work with battery suppliers to bring customers fully developed energy storage systems for their EV charging station(s).

“The batteries can hold a lot of energy in a small space,” Morin added. “The ones we use are very safe and energy dense.”

Our two main solutions when it comes to energy storage for EV charging stations are the MPS-i Energy Storage System and our CPS-i Energy Storage System. This means we can serve smaller application sizes such as ones found at your local fueling stations as well as larger ones associated with fleet charging applications for delivery services. And with our DPS-500 DC-to-DC Converter, any one of those installations could utilize power generated via solar panels to power the EV charging station—making it potentially fully renewable.

“We’ve deployed battery energy storage systems for the charging of planes, trains and cars but the rate of change and the need for widescale charging deployment is accelerating our work,” Morin added.


In fact, we’ve worked with customers who utilize electricity from the grid and renewable sources along with an energy storage system to not only save money on demand charges, but to even sell power back to the Grid in utility services markets.

“Operators of battery storage enabled EV charging not only have the opportunity to make money off fueling of EV vehicles but selling power into the energy markets at the appropriate times,” said Morin.

And, just as with our rectifiers, Dynapower’s energy storage systems are built around efficiency, safety and reliability.

“The power electronics is the glue to it all,” said Morin. “We’re now partnering with charging manufacturers to create a fully integrated system where they provide chargers and we provide the battery storage.”

For years, Dynapower has specialized in installing microgrids—which carries over to our work in e-mobility. We’re proud to be playing a role in the story of e-mobility by leveraging our trusted equipment to allow for the adoption of widespread EV charging.

While we don’t produce clean energy, we help supply the power that makes it possible. In that sense, Dynapower is at the heart of the clean energy revolution and we couldn’t be happier.

More About the MPSi-125 and the CPS-i

The MPS®-i125 EHV is a 125kW behind the meter Energy Storage System that combines Dynapower’s highly efficient UL 1741 SA certified MPS®-125 EHV with Li-Ion batteries in a temperature controlled NEMA 3R-rated battery enclosure. This system also features Dynapower’s proprietary Dynamic Transfer™ which, in the event of a grid disturbance, seamlessly switches a facility from grid-tied to battery backup power.

The CPS®-i is a fully-integrated front of the meter energy storage system that combines Dynapower’s efficient UL 1741 SA listed CPS®-1500 or CPS®-3000 with Li-Ion batteries in a temperature controlled NEMA UL 3R / IP 54 (outdoor) rated battery enclosure with all associated controls. Multiple CPS®-i systems can be paralleled together to meet the sizing needs of any front of the meter installation.
