EVgo Wins Energy Storage North America 2016 Innovation Award



A Stationary Storage + Electric Charging (SSPEC) infrastructure project made by EVgo and UC San Diego about year ago, has won a Energy Storage North America 2016 Innovation Award.

The station reminds us of a traditional gas station, but of course with no liquid fuel pump there.

Instead, two DC fast chargers for both CCS Combo and CHAdeMO charging (50 kW each) are present, as well as a AC charging station, solar roof and on site energy storage system – consisting of used batteries from BMW i3 electric cars.

According to press release, over 100 drivers are using the station every week, which translates of course to some ~15 per day.

This award-winning station is a precursor to the install of America’s first ~350 kW super-station, which EVgo is presently constructing in Baker, California.  This 350 kW station also has a solar canopy, a battery back-up/storage system, as well as both CHAdeMO and CCS Combo connections.

EVgo statement in the win:

“A pioneering program in lowering the cost and immediate power demand of EV charging to host facilities, the EVgo SSPEC project explores how incorporating energy storage along with DC Fast Charging infrastructure can reduce the overall costs to public stations in order to make charging more accessible to EV owners. The SSPEC site is a model for future public charging facilities thanks to its use of four second-life batteries pulled straight from the BMW Group’s retired test fleet of electric vehicles, along with its use of solar power generation and intelligent site power control.”

“For the SSPEC project, EVgo partnered with the University of California San Diego, which is recognized as one of the top 15 research universities worldwide and operates what is considered one of the world’s most advanced microgrids. EVgo worked with UC San Diego to locate a demonstration site on the campus microgrid that would also ensure the stations would be accessible to the public and which results in the chargers serving over 100 drivers per week. The project is part of the CPUC Technology Demonstration Program, a program designed to help demonstrate the benefits of energy storage coupled with public DC Fast Charging stations.

The EVgo SSPEC system leverages a total of four second-life battery packs to provide energy storage services at the site. Local site controls then dispatch the batteries to provide services when vehicles arrive to charge at the site. With the system’s solar charging integration, customer vehicles charge directly from solar energy generated on site, and the batteries are used to reduce the grid’s electricity consumption, effectively offsetting demand charges and helping to manage the operational cost of providing public charging services.”

Terry O’Day, Vice President, Product Strategy and Market Development at EVgo added:

“DC Fast Charging plus storage presents an exciting opportunity for drivers and charging companies alike. This project has the potential to shortcut some of the barriers facilities face when looking to install DC Fast Charging stations by reducing operating costs, improving charging service and convenience for EV drivers, and ultimately can help to put more electric vehicles on the road,”

    I counted 40 panels, which likely means ~10-12 kW nameplate capacity, right?
    Given the sunny low-latitude location, they probably produce ~25MWh per year, enough for several thousand of Leaf-like charging session, the majority of sessions at that station according to the 100/week quote.

    I wonder though, how come there are already aftermarket i3 batteries, when that EV has been selling in the US only since mid-2014? Or are these production rejects?

    Sorry for getting into the weeds. This is a cool accoplishment and a nice academic/business partnership (from experience, never an easy prospect to pull off).

      …which reminds me, the story title should change to “UCSD and EVgo”, rather than “EVgo”. At the very least, UCSD provided the site and part of the know-how.

    Excellent template, now let’s see some numbers! With four 22 kWh packs, each accustomed to 125 kW peak loads, a single 50 kW DCFC session should be effortless. Assuming thes facility only uses a single phase 240 Or 277 V grid connection at 200 amps or less, installation cost should be much less. However, if on high Voltage service as part of a larger facility, the demand charge mitigation would be far more valuable than any EV charging business.

      “…Assuming thes facility only uses a single phase 240 Or 277 V grid connection at 200 amps or less,…”

      Why would you make the assumption that a relatively large commercial facility would only have 48 kw available?

      Areas are different, but in my area the utility provides absolutely no savings for single-phase commercial customers, and depending on the location limits single-phase commercial draws to either 50, 75 or 100 kw (Unless it is convenient for THEM, of course).
