(1) FreeWire offers battery-integrated electric vehicle charging solutions that enable ultra-fast charging without costly grid upgrades. Their Boost Charger uses an integrated battery to store off-peak energy and discharge it to power rapid EV charging. (2) Installing a Boost Charger is much lower cost than traditional chargers, which require extensive and expensive grid infrastructure upgrades. A Boost Charger can support charging 15+ vehicles per day while only taking up 1-2 parking spaces. (3) Battery integration provides benefits like reduced demand charges, opportunities for lower driver fees, and easier installation in multi-unit dwelling and mixed-use development applications compared to standard chargers.

• Today’s EV charging technology is entirely dependent on grid infrastructure
that can’t support the power requirements of ultrafast charging.
• In California, commercialand retail locations cannot accommodatethe additional load required to enable fast and ultrafast charging of electric
vehicles. The California Energy Commission refers to this as the “Red Sea.” Globally, over 17TW of generation capacity additions and
~$14.0 trillion of grid investmentis needed between now and 2050, which is unlikely to occur.

Grid upgrades and
construction projects
severely impact the
deployment time of
ultrafast chargers – up to
30 months for permitting,
easement, civil works, and
construction.
Each fast charger can
require $100K+ in
infrastructure costs alone.
Current EV charging
solutions are inflexible
because they require
significant capital
infrastructure, which is
underground and cannot
be relocated.
Conventional Fast Charger Deployment Challenges
Fast and ultrafast EV
charging at scale requires
extremely high-power
outputs, but the grid edge
has capacity limitations.
Time Delays Inflexibility

High Costs
For higher-powered sites and remote sites, utility-side infrastructure costs can be

• Deployed Mobi Charger at an apartment complex in 2020
• Difficulty finding properties for study due to the pandemic, but found a property
manager that had 5 EVs on its property in San Mateo
• Project Benefits:
• Mobi enabled the property owner to not install any permanent
infrastructure
• Charging costs were low as Mobi stored off-peak energy
• Project Challenges:
• Mobile charging solutions need to be attended by someone who knows
how to operate the charger. Residents unfamiliar with charging
technology may be confused
• High cap-ex of charging station makes it difficult for property owners to
purchase
