The System is the first of its kind to use Princeton Power’s Demand Response Inverter

Princeton Power Systems(PPS) turns on its Energy Storage System (ESS) at BMW Group’s Technology Office in Mountain View, CA. The ESS is the first of its kind to use PPS’ new Demand Response Inverter in an integrated system.

The ESS, consisting of a 100kW Demand Response Inverter (DRI-100) and 30kWh lithium ion batteries, will be used to store renewable energy from the on-site solar array, reduce peak electricity demand and demonstrate DC fast charging technology for electric vehicles. The Princeton Power ESS is just one piece of BMW Group Technology Office’s USA e-mobility lab, a smart-home and electric vehicle ecosystem demonstration.

“Sustainability is a core mission of the BMW Group. The Princeton Power Energy Storage System will ensure that BMW Group Technology Office USA is using renewable energy reducing its impact on the electric grid,” noted Dirk Rossberg, Head of the BMW Group Technology Office USA. “More importantly, we’ll be gaining valuable insight into how these systems can be integrated on a broader scale in the future.”

The DRI’s direct DC power routing capability demonstrates one of its critical advantages over other available inverters on the market. “These advanced capabilities make BMW’s charging system much more flexible than a typical charging station, and suitable to the deployment of both electric vehicle charging and smart grid applications,” said Darren Hammell, Executive Vice President at Princeton Power Systems.

PPS’ DRI-100 was introduced in 2011 as an advanced bi-directional multi-port inverter with the ability to directly route power through its multiple AC and DC terminals, revolutionizing applications such as electric vehicle charging and demand response. PPS received an R&D 100 Award for the DRI Technology.
