The new #Peregrine #EnergyStorage Project clocks in at 200 megawatts (MW)/400 megawatt-hours (MWh), making it one of the biggest battery storage facilities in the #SanDiego region. That’s enough stored energy to power around 200,000 homes for two hours during peak demand.
Built for $300 million, Peregrine is the fifth utility-scale energy storage project #Arevon has launched in #California.

Electrek · This new San Diego battery can power 200,000 homes during peak hoursBy Michelle Lewis

Yeah... That went well: ourobengr.com/2025/08/yeah-tha - The latest in my long series of posts about our 5.94kW solar array with Redflow ZCell battery and Victron Energy inverter/charger system, wherein our battery that replaced the first one under warranty itself failed for the same reason. Happily we were able to get it replaced again, but not through Redflow who no longer exist. I've also included some speculation about why these batteries fail, and some possible mitigation strategies in case other folks with ZCells are still running and want to stay that way.

I finally got round to taking this LG Chem #RESU10H battery apart. These are the 6 cell packs, originally all in series for 155vdc. I will be restringing them as 2s3p for a 48vdc nominal pack, and implementing a new active balancing BMS.

The battery disabled itself, throwing an error code with #30, which indicates the cell with an issue. Sure enough, the one pack's voltage with cell #30 is about 0.4v lower than the rest. Since these are NMC, absolute care must be taken in any resolution.

New paper just out today: *A dynamic model of a power conversion system with indirect thermal energy storage for a pulsed fusion tokamak for use in design optimisation*.

The DOI doesn't work yet but DM me for a share link from Elsevier if interested.

@glitzersachen @leanlearnlead granted the faster a battery is charged, the less efficient it is and the more straining it is on the battery chemistry.

But aside from that, there's no reason why #BEV #Charging needs to be more complex than these few steps;

1. plug in the vehicle with a CCS2 plug
2. select the amount of kWh / money one.wants to spend. (being able to abort if the energy price is abdurdly high!)
3. pay with card (NFC+PIN).
4. upon payment confirmation, the vehucle gets charged and the charging station shows an estimated completion timer & offers sending a notification via eMail or SMS.
5. Once completed, the charging station will unlock the plug/socket and send said notification out. In the meantime another customer could just pull the unlocked plug and start their charging.

Just like on a (abeit slow) gas pump!
