Replying my own message, in case somebody is curious:

It will be a 111kWh CATL-made, Lithium-Ion battery. 400v architecture, structured in 17 modules and 204 cells (12 cells per module).

Out of the 111 kWh only 107 kWh are usable.

This battery will be able to charge at 11 kWh on AC and 250 kWh on DC fast charging.

Now... I heard that the new EM90 mini-van might get an optional 140 kWh battery (or the same 111 kWh as the EX90).
Immediate question pops to mind: won't the EX90 offer an upgraded Extended Range 140 kWh battery as well?

If it did, it would change everything.

It would be nice to gather your thoughts.

 

140kw is overkill IMO. If you have a real world range of 450-500km, the best choice is to have a fast charging capability for those long trips. Added battery means added weight, which is bad for everything

 

You might be right, however, it's all a question of how fast will you be travelling. It's relatively easy to achieve 500km in the city circuit. If you get on the road, 120-140 km/h are very difficult to sustain for longer trips in an EV. My wife's XC40 Recharge cannot make 300km on the highway, in spite of the stated 450km range.
We often do the Lisbon-Porto trip in Portugal (310km) and in her car we have to stop for a recharge or we won't reach our destination. True, it's highway all the way.

I am curious about the EM90 specs in comparison with the EX90.

 

Our C40 is even worse. 160km on highway, 130 kmh, heating and lights on, eats 65% of battery.

 

The only solution is to have better aerodynamic efficiency which Volvo is lacking significantly compared to others. I do not know the math but I’m guessing a 10% lower cd value would give a similarly longer range?

 

The Volvo EM90 would appear to be the rebadged and tweaked version of the (Geely) Zeekr 009 which is based on the SEA platform. The EX90 is based on the SPA2 platform. My hunch is the SEA and SPA2 battery designs are different enough that you probably won't see interchangeable battery configurations.

There is also some tradeoff here. These EVs are darn heavy as it is - adding more weight for even larger battery may not be optimal. I'd rather the industry focus on faster / more efficient charging rates, and getting more of those chargers in more places.
