Project Update

In 2022 the project team continued engineering and design of its Phase 1 (Boos Charger+) and Phase 2 (Boost Chager 2.0) products including software, mechanical, and structural updates. The project team also conducted testing of a prototype unit where the unit charged and discharged batteries from the grid. The project team also prepared draft versions of procurement, construction and installation plans in prepration for construction and installation activities in 2023.

The Issue

With the ongoing challenges presented by the state's wildfires and Public Safety Power Shutoffs, the electric grid requires increased resiliency and power demands on the grid must be reduced. Currently, conventional electric vehicle charging systems are typically tied directly to the grid without battery backup or other on-site storage. Boost Charger's integrated design will leverage on-board battery storage to combine grid-down DC fast charging with full microgrid integration and controls, creating simplified turnkey installation that can accelerate deployment.

Project Innovation

This project will finalize development for and demonstrate a direct current fast charging system (FreeWire Boost Charger) for electric vehicles at two Bay Area gas stations, one of which is located in a disadvantaged community. One of the demonstration sites will further leverage on-board battery storage to combine grid-down DC fast charging with full microgrid integration and controls. In addition, this project will reduce energy costs through peak demand reduction and demonstrate ability to operate critical site loads for at least two hours.

Project Benefits

Executive Order B-16-2012 called upon state agencies to support benchmarks to ensure that Californians have easy access to ZEV infrastructure by 2025, and Executive Order B-48-18 set targets of 250,000 electric vehicle chargers to support 1.5 million zero-emission vehicles on the road in California by 2025, and 5 million by 2030. Direct current fast charging deployment is significantly constrained by site installation costs, and site hosts are strongly concerned about reliability. The project will greatly reduce the installation and operational cost for DC fast chargers by minimizing utility upgrade requirements and demand impact. It will also provide a resiliency solution to improve reliability for site hosts and fleet operators.

Lower Costs


The project will directly reduce electricity costs for site hosts in comparison to conventional DC fast chargers. Power from the battery will be stored during cheaper off-peak periods, resulting in lower per kWh charges.

Greater Reliability


The project will directly and indirectly support multiple categories of reliability benefits for IOU ratepayers.

Increase Safety


The proposed system will be fully UL certified and compliant, ensuring that it is able to fully integrate into a grid power or microgrid scenario while providing the benefits identified above.
