Wipomo’s Mobile Energy Ecosystem

Off-grid Plug-In Vehicle & small electronic charging station

Our off-grid, Plug-In Vehicle & personal electronics charging station delivers “Power when you want it, where you want it, day or night, even during a utility blackout”.

You can save with Wipomo’s Energy Ecosystem, and now we’re bringing it to you so you can see for yourself. The Wipomo Mobile Energy Ecosystem is an on-grid and off-grid charging station that demonstrates the versatility of Wipomo’s Ecosystem. Wipomo saw the potential for a mobile demonstration unit in the first iteration of the then called Solar Slider. Two versions later, the Mobile Energy Ecosystem now has an advanced energy management system that accepts energy from solar photovoltaic modules, batteries, grid connection via a standard 120V outlet and input from an electric vehicle. The electricity flows through the whole system, recharging the batteries, powering loads and sending excess energy back to the utility, if available.

Upgrading the unit started and ended in August and Setember of 2013. Wipomo supplied the electronics that make the Energy Ecosystem possible while Roger Davenport, an advisor, designed and installed the system. The Wipomo team took the Mobile Energy Ecosystem to the Sustainability Tour at UC San Diego for the commercial tour and then to Wipomo’s Home Showcase for the residential tour (pictured above). After another round of improvements for safety and display, the Mobile Energy Ecosystem is ready for more events.

Wipomo’s Mobile Energy Ecosystem – UCSD debut

Mobile Energy Ecosystem by Wipomo and Butler Sun Solutions

Wipomo unveiled the Mobile Energy Ecosystem at UCSD, during the 13th annual San Diego Sustainability Tour, an event organized by the San Diego Renewable Energy Society.

The Mobile Energy Ecosystem is second generation off-grid electric vehicle and personal electronics charging station, designed by Wipomo and Butler Sun Solutions, Inc.

Wipomo’s design made it possible to power a house or business from an electric vehicle.

During the event, Wipomo demonstrated vehicle-to-vehicle (V2V) high voltage power transfer, through the Mobile Energy Ecosystem. Our design shows that electric vehicles and distributed power generation can provide wide ranging possibilities, from EV rescue, to ancillary services for the utility.
The first generation system, called the “Solar Slider“, powered up students between classes at UCSD for more than a year, and served as a renewable energy educational tool.

The Solar Slider is the result of a SunEdison grant awarded to Engineers for a Sustainable World (ESW), to build a “Green Island” utility vehicle and electronics solar charging station for UCSD campus.

ESW@UCSD students designed and built the solar PV deployment cage and hydraulic lift, attached to a single axle trailer.

Charlie Johnson, Wipomo, CEO, participated in the ESW Solar Slider project as grant writer for the SunEdison “Green Island” national contest, and as a community leader in assisting in organizing a student ASES chapter at UCSD, fulfilling his pledges as an elected board member of the San Diego Renewable Energy Society.

Solar Slider debut at UCSD

Wipomo and ESW at the debut of the Solar Slider at UCSD

Wipomo sponsored the unveiling of ESW’s “Solar Slider” electric vehicle and charging station at UCSD.

The “Solar Slider” popped pop-corn and cotton candy for students between classes, to demonstrate solar power generation and energy storage, in a park setting.

Solar Slider Design & Assembly

Led by SDRES board member and UCSD Engineering professor, Kurt Lund, PE, the Engineer’s for a Sustainable World design and build the cage to be mounted on a trailer, to raise and deploy a 2kW DC solar array.

Our advisor Kurt, a professional engineering consultant, graciously opened his garage, tools and skill up to us for building the cage. As a group of undergraduate engineers (and one Psychology Major), we knew we had many hours ahead of us and plenty of “learning incidents” (where we completely mucked a few things up and had to fix it), but that’s why we started this project in the first place. -Joseph Ocampo, Wipomo Research Intern

ESW on CarTalk for “Green Island” at UCSD

Joseph Ocampo takes the Green Island project to radio on CarTalk, to promote sustainability education for renewable energy and electric vehicles at UCSD. With help from Kurt Lund (SDRES, UCSD PE) and Charlie Johnson (SDRES, Wipomo), the Engineer’s for a Sustainable World take a victory lap for their grant awarded project for on-campus off-grid, solar powered, electric vehicle charging station on a mobile trailer.

ESW / UCSD awarded a SunEdison grant

The Engineer’s for a Sustainable World (ESW) chapter at UCSD was awarded a grant by SunEdison to build a “Green Island” off-grid electric vehicle and personal electronics charging station, to be used to by the students and staff, as part of a renewable energy education campaign to support UCSD’s campus green initiative.Charlie Johnson, on behalf of Wipomo, and as elected Board Member the San Diego Renewable Energy Society, was a grant writer for the awarded project.

Joseph Ocampo, the ESW student group project leader and Wipomo intern, worked as a liason between UCSD and for-profit corporations, to solicit additional contributions, in funding or in-kind expertise.
