Standardization
 Cell test plan is elaborated & ready
for G0C, G1C, G2C cells in FiveVB
 Selection of adequate testing standards
for technology, among others:
IEC 62660, SAEJ2464...
 Exchange in progress among
all three GV1 consortia:
eCaiman, Spicy, FiveVB
→ Aim:
Recommendation of teststandards
towards standardization commitees

Industrialization – PHEV1 cell
Main Tasks:
• Task 1: scale up of anode: completed, ~800m of double
side coated electrode ready
• Task 2: scale up of cathode: completed, ~600m of
double side coated electrode ready
• Task 3: PoC for large cells (PHEV1)
• Task 4: Formation and initial performance tests
• Task 5: Spec. industrial scale-up
Left: anode coating
Right: ready anode rolls

Feasibility – system concept
Module
 Energy content: 2.02 kWh for a 12 cells
module
 Min./max. Voltage: 9.6/20 V – for a 4s3p
configuration
 Module weight/volume: 11.22 kg /
4.54 L
 MCU (module control unit): no
 Dimensions: 308*112*175 mm
Energy Density
 Gravimetric: 180 Wh/kg
 Volumetric: 444 Wh/L
approx. 30% increase vs.
state of the art; tbc by tests
needs to be put in context with
system technology & cost analysis
Thermal Management
 Liquid cooling; Al cooling plate
 Gap filler (thermal resin)
 Highly efficient cooling & heating
→ Module manufacturing with PHEV1
cells scheduled in Q1/2018
→ One of major issues regarding cell
& system manufacturing:
‘Swelling’ - Cell dimension
change depending on State of
Charge & ageing
- topic tackled in round
table approach

11. This project has received funding from the [European
Union’s Horizon 2020 research and innovation
programme under grant agreement No 653531
Impact & Outlook
 Prove of concept for new Li-ion chemistry & manufacturing
based on industry standards accomplished
 Test methodologies available for next generation Li-ion cells
 Standardisation discussion on ‘GV1-level’ for testing
→ common workshop at TRA in April 2018 in Vienna in planning
 Durability as an issue → needs to be investigated from system level over cell level
down to cell material level
→ specific challenge: ‘Swelling’ – Round table approach as highly valuable
methodology
 Comment on future perspectives:
many challenges solved, but still many challenges pending
→ established structures from Research consortia can help to tackle these issues
fast & efficient
