Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Yeah pretty much what I said on the first page. http://forums.aeva.asn.au/viewtopic.php?p=66788#p66788 So typical use for this product is one charge/discharge cycle per day. 10 year warranty is 3650 cycles. So LTO's will easliy do 10x that. So the cycle life will never be reached. Only the 10 year l...

Re: Proposed "New Energy Industry" CRC for Australia!

There's money to spend. We just need to spend it on smart stuff like manufacturing and processing, and not dumb stuff like housing estates or bitcoin. I agree. And in the end Australia gets more money if we are value adding rather than sending off raw materials. Well at least we weren't duped like ...

Re: Proposed "New Energy Industry" CRC for Australia!

Battery manufacture in Australia should cost exactly the same as anywhere in Asia. The entire process is done by machines and they cost the same no matter where you build them. No way. Land is different. Regulations are different. Shipping is different. It isn't a lights out process so there will b...

Re: Proposed "New Energy Industry" CRC for Australia!

Yeah there is a reason we export raw materials. 1. It is cheaper to process overseas. 2. Less chemical pollution in Australia when processed overseas. 3. Large capital expenditure required to start processing in Australia. 4. To a lesser extent we don't have the technical capabilities to as good a j...

Re: Large ebike packs - how are they?

Oddly the cheapest that I have found are the balance / hover board packs which are 36V 4.4Ah. They are made from 20 x 18650's and have BMS built in. 1 x 48V20Ah=960Wh for $595 vs 6 x 36V4.4Ah=950Wh for ~$390. 112844990880 https://www.ebay.com.au/itm/4-4Ah-36V-Li-Ion-Battery-Pack-Self-balancing-Elect...

Re: Powering the home from spare EV charge?

I was under the impression the only batteries would be in the car. So no dedicated home storage. The ev powers the house during peak times. The grid charges the ev during off peak. You could probably do it with one cable. But have 2 connection points on the house. One for charging the other for supp...

Re: The Energy Retailers Strike Back. Will Cheap Off Peak Rates Kill Battery Storage?

It's just an example - there are always variations and exceptions to everything. You don't save $0.50 you only save $0.25. And only on things that you can't move to off peak - like cook dinner etc. True about the supply charge but it's 3kW to be on grid. That same 3kW would charge the pack off grid....

To make matters worse add in the daily electricity supply fee and the lost $12,500 that was tied up in the powerwall. For me the powerwall numbers don't add up for home energy storage. Or really for any lithium battery for home storage. The energy providers have a cost to produce energy. If they mak...
