  • Bi-directional EV Charging [PDF - 205 KB] turns EVs into energy storage assets, increasing resilience and lowering the cost of EV ownership.
  • DC Microgrid [PDF - 189 KB] connects on-site energy generation and storage devices to direct current (DC) loads, eliminating conversion losses and optimizing the efficiency of on-site power.
  • EV Charge Management [PDF - 202 KB] integrates embedded vehicle telematics with utility signals to optimize charging based on vehicle use, utility rates, and the carbon content of delivered power.
  • Modular Charging Station [PDF - 203 KB] combines a 4.3 kW solar array with lithium-ion battery storage and emergency power panels to deliver a grid-independent and transportable energy source.
  • Single-Axis Solar PV Tracker [PDF - 203 KB] promises to increase commercial rooftop solar photovoltaic production by adapting a proven utility tracking technology with a new low-profile rocker design that reduces friction, motor size, and the cost of sun-tracking.
