1. Batteries as a Service

2. The EV challenge: a great divide !
 Moderate battery
 Slow demand-response residential charging
Tax neutral
Profitable
Competitive TCO
 Very large battery
 Very fast synchronous charging
Convenient
Versatile
Low life cycle Impact
Low Grid impact

3. EVs: how much battery is required?
Battery utility:
0-20 kWh : 87 % of all daily usage
+20 kWh: +9%
+20 kWh: +1,5%
+20kWh: +0,5%
If 20 kWh has a « cost » (or impact) of 1unit per day of usage:
+20kWh costs 11+1=12 / day
+20kWh costs = 79 /day
+20 kWh costs = 279 /day …
The long term limit to battery size isn’t technology, it’s the marginal utility.

How ?

8. Benefits The battery is sized to satisfy 98% of usage
Price parity with ICE
Lowest carbon footprint over life cycle
Profitable
Sustainable
Additional range on a pay per use basis
Traveling with peace of mind
Tender is booked ahead of the trip
Tender is swapped when depleted (60kWh in 1’ is 3,6MW charging)
Travel time remains under control

9. Energy distribution benefits
Petrol pumps
600km range in 5’
Stretch legs
Get food and sundries services
Little risk of queues
Fast chargers
250 km range in 60’
Stretch legs, read books, and watch videos…
Material risk of queues
Severe grid impact & high carbon mix
Major investment
EP Tender
300km range in 1’
Grid services and charger support
Renewable energy

10. Retaining the best of battery swapping
Batt. Swap.
Range extending as a service (pay per use)
Optimised life cycle carbon footprint
Optimised vehicle cost
Battery swapping time
Variable range without payload impact
Cost of the rental/swapping station
Impact on the vehicle’s design
Adressable EV models
Multienergy ability
Share of fixed costs vs variable costs
Maintenance costs of rental points
Progressive ramp-up ability
Capital intensity

11. The environmental impact
Model used in this Life Cycle Analysis, EU electricity mix and 5% of the kilometers driven with a Tender
Climate change:
EV + EP Tender has a lower impact than EV with big battery.
EP Tender enables demand-response charging.
Based on N Hooftman, M Messagie “In-life range modularity for electric vehicles: the environmental impact of a range-extender trailer system” :
Super fast spot charging
Residential demand-response charging
M. Messagie, F.-S. Boureima, T. Coosemans, C. Macharis, and J. Mierlo, “A Range-Based Vehicle Life Cycle Assessment Incorporating Variability in the Environmental Assessment of Different Vehicle Technologies and Fuels,” Energies, vol. 7, no. 3, pp. 1467–1482, Mar

12. Impact on cities Paris Less pollution in big cities: Matches with ULEZ
Easy deployment: Paris and London: 28 stations serve 15 millions of inhabitants
Londres

13. Batteries in the cloud, providing value at all times
Inverter
Grid
400V DC bus
When rented: a range extender
More range on demand
Rescue service when « out of juice »
Zero emission genset for events or works
When stationary: a virtual powerplant
Frequency regulation
Buffer for fast chargers
Available where demand is
Storage for self consumption

14. EP Tender sweet spot
Fuel tank:
2350 Wh/kg,
1USD/kWh,
2 MW charging

15. 2030 Vision Vehicles are clean, connected, autonomous and lean.
Their range is adequate for daily usage.
During long distance trips, a self hitching energy module (a Tender) complements their internal energy storage.
Tender-to-grid

16. The business model Range extending service for EVs Revenues
- High client value
- Margin protected by patents
- Recurring business (“sticky” business)
Distribution
- Low client acquisition cost (via car dealers and fleets)
Growth
- Scalable business (wireless rental management)
- Variable costs
- Global market
- Growth >20% for decades

17. Our fundamental beliefs
The real issue is the marginal requirement of long distance trips vs the marginal cost of providing it. It’s no longer battery technology.
The range problem will last over the long term
We are technology agnostic! We will benefit from technology progress, and in particular battery progress… (+ fuel cell, dynamic inductive charging, etc.)
Pay per use is a growing trend for expensive and seldom used features
