Arcady Sosinov of FreeWire Technologies' talk on mobile charging enabling the EV Ecosystem at the EV Momentum Summit Berlin, 21 June 2018

1. Mobile Charging to
Enable the EV
Ecosystem

2. The Rise of Electric Vehicles
are expected by 2025.
40-70 million
electric vehicles
To support this evolution, approx.
4.5-5.5 million
charging points will need to be installed
by 2025.
According to the IEA 2017 EV Outlook

3. Uncertainty Change

4. Challenges of Fixed Infrastructure: Supply
time-consuming, permanent and can be cost-prohibitive
Permits Construction
Transformer Upgrade
or New Service

5. Challenges of Fixed Infrastructure: Demand
underutilized and outdated
Workplace Charging:
Productivity loss/hassle
Employees worry about access to
charging and spend an average 30
minutes moving their car to secure a
charge.
Fixed Charging:
Underutilized stations
Not enough historical basis for
placement of charging stations leading
to low utilization, typically
2 charges per day or less.

6. Challenges of Fixed Infrastructure: Grid
100kW out100kW in
100kW out14kW in
Ten 20-minute charges per day for 30 days cost:
$2,000 (Energy Charges)
$3,000 (Demand Charges)
Total = $5,000
$16.67 per charge
$1,270 (Energy Charges)
$420 (Demand Charges)
Total = $1,690
$5.63 per charge
Off-peak energy pricing = $0.10/kWh, peak energy pricing = $0.20/kWh, demand charge = $30/kW.

7. Enhancing the Charging Experience

an easy, full-service EV charging
service for workplaces and beyond

8. Electrification Beyond the Grid
• Lower costs: Off-peak charging reduces
electricity and demand costs, no (or limited)
need for infrastructure upgrades, no loss of
parking
• Greater Flexibility: Charge vehicles where
they are, serve sites where fixed charging is
prohibitive, change service locations, easily
scale to meet demand
• Higher satisfaction: Easy to manage, high
utilization, seamless user experience (drop a
pin to request a charge, get a text when
complete)
Mobile charging as a
flexible complement to
fixed infrastructure

Mobile Charging Process
Features
FreeWire maintains and
upgrades equipment
Ability to mix and match
charging speeds based on
driver needs
Flexible options to move
service location

10. Site Assessment & Management
Problem
• Limited knowledge of EV
charging patterns
• Changing traffic patterns with EV
adoption
Solution
Collect data about utilization to test locations before setting up stationary equipment
Test necessary charging speed of stations without grid infrastructure upgrades
Potentially results in underutilized
charging stations

11. Deep Tech Dive
Mobile EV chargers with onboard lithium-ion energy storage enable dual Level 2 or DC Fast Charging
Mobi Charger L2
• Level 2 charging
• Dual J1772 plugs delivering 7.5kW each
• 40kWh or 80kWh storage capacity
Mobi Charger DC
• Delivering 50kW
• CHAdeMO plug
• 80kWh plus storage capacity
Form Factor Options
• Self-propelled – on-board motor for short distance travel without additional power
• Trailer-mounted – robust large wheels for long distance travel

12. Infrastructure Optimization
EV charging sites having challenges with
traditional solutions are now serviceable
Property ownership: short-term lease
Expensive to serve growth: fixed stations trigger
grid upgrades
Cost-prohibitive (e.g., demand charges)
Infrastructure constraints
Flexibility
Scalable EV charging network that
operators can further optimize
Test demand before using fixed stations
Future-proofing the network – ability to scale
technology mix with demand
Customize program to users needs
Mobile Charging is Accelerating EVs
