Upgrade battery to 48kwh..

[aventuri]

It looks like a chinese firm Is going to sell 48kwh batteries for eGolf in Europe.

Are you interested, eventually?

I talked with a guy on WhatsApp and he said they start end of year. I'll wait and see..

It is a bit suspect that the photos of the "e-Golf" shown are combustion Golfs. Also, energy density is barely better: 193 Wh/kg for original "large" pack and 202 Wh/kg for new pack. I think it should be on the order of 10 to 20% better gravimetric density considering the age of the 35.8 kWh pack.

certainly interested depending on the price!

MTG and CATL are both legit Chinese NCM battery suppliers, but agree, gas engine Golf image is incongruent.
Good note on density. New 48kWh pack = 238kg; Std 36kWh = 185kg.
Yes, additional "35% more energy" but also extra 30% more mass.
But... 208km vs 280km range (130 vs 175mi) does have some appeal as well.
I'm certainly curious - especially if pricing isn't outrageous.
Also wondering about complexity of updating battery management/ECM to recognize new higher capacity pack.
Though (optimistic) perhaps by point these new packs are available there will be "tuning" available for eGolf ECM...

very very complex I suspect. For the expected large cost, range should be over 200 mi I think. Also, not sure e-Golf is a big enough market for a product like this, considering battery deg is minimal given passively cooled pack design.

if not egolf, then which market with conscious edrivers would ever be? genuine newbie question, because i will always prefer ev with minimal battery deg, and not many options out there, still life changes, and range needs change. golf has 40y.

My 2015 eGolf is on a pretty short leash now, at <70 miles, so yes, I'm interested, tho not in a big hurry. Upgrading the ECM/controller will be an issue. I wonder if I can keep the old battery as a home powerwall?

What price point would interest people?

What price point would interest people?

i'm not the one asked to reply, anyway if i can express my opinion, i'd pay 100€/kWH.. i.e. for a 50kWh i'd pay 5K€ if the battery is reliable/insured/installed properly and so on

let me add also that after the EV battery upgrade, we would be left with the original as spare. and that would have some relevant value still: we could use as huge "energy storage" for home PV

OTOH if the installer would be willing to retire it, i thnk it could be valued a 60€ * 36KWh = 2K€

so the upgrade could be a 3K€ job. i'd like to know if thats' a reasonable approach

BTW the first "customers" should get a "better" treatment, as we are talking about taking kind of a risk, as we are pioneering a though implant: who knows it's going to be as smooth as we hope..

I want anyone’s input on what they think a reasonable price for a battery replacement would be.

Do you need one?

Assuming $100/kWh (probably optimistic) and 8 hours of labor I do not think this job can be performed for anything less than $6000.

 

[Fugazi]

I'd say $100/kWh is not realistic. For that price I would buy. Already to get the original for my house.

Another issue not mentioned here is; how easily (size) can you fit a bigger battery? From the specs the new sounded to be same energy density and this probably means it would be as much larger too.

We own a 2019 SE with approx 22K miles and approx 39 months on the battery warranty. We are charging it to 90% and we can drive it 70miles and still have 70 miles of range available.

I could see owning the car for 20 years. I could see replacing or upgrading the main battery pack once during that period. I think it would be reasonable if the cost was $6k to $10k for a replacement battery pack. Or a monthly cost in the range of $125.

At one time I heard that there was a program with the MB Smart EVs were the owners were actually leasing the battery packs and paying a monthly fee.
