LiFePO4 lithium battery fires and explosions
Posted by: @transparentI too had spotted the Na-ion battery and matching inverters from Eleven in Cambridge.
it's good to see a British company designing something for the obvious gap in the market.Note that their inverters can only be used with their own Na-ion battery.
It's not a generic approach. They need to be transferring data between their own BMS and the inverter across the CAN-bus to make the system work.
This is one of the few that splits the components: battery and inverter, but I also noted that they are not meant to be used except with each other. Eleven are clearly aiming for a battery pack voltage range around the lithium ones, so more cells must be used. This should obviate the issue with very thick cables.
In terms of providing protection for power outage, these manual systems do not make much sense at this scale, specially as the competition is very mature.
And I also did not find a proper diagram that includes the sodium batteries.
I think vicron was one inverter brand that folks were trying to use with sodium, but I did not look much into it.
