Benefits and Challenges : Opportunity Charging Concept
Opportunity changing concept have benefits to depot charging
thanks to smaller battery in capacity, volume, and weight.
� More Passengers
� Better Energy Efficiency
� Lower Recycling Cost
� Lower Environmental Impact
But also challenges…
� High charge power acceptance (4-5C charging during 5-10 min.)
� Long cycle Life (15 times x 365 days x 15 years : 82,125 cycles)
� High output / input power for acceleration and recuperation
with relatively small capacity.
Optimized for TCO
