Everyone remember: Volkswagen have announced a firmware update for the ID.4 which ramps up to peak level earlier, tapers off later, and increases that maximum rate from 125kW to 135kW. It's just an 8% increase in peak level, but the prolonged hold at the higher rate means the car can charge from 10% to 80% capacity around 23% quicker than before the firmware download. These OTA (over-the-air) updates allow EV makers to tweak things like the useable battery percentage, the charge curve, even the rate of acceleration under certain settings. It's a brave new world where we have to stop thinking about vehicles as having static and set components with locked-in attributes. If real-world running shows the Subaru can be upped from 100kW peak without undue damage to the CATL battery pack, one OTA update will open that up to owners.Green Car Reports mentions the battery differences between the AWD and FWD Toyota Bz4X.
Seems the AWD vehicles will have CATL sourced battery limited to 100kW charging. Assuming the Solterra will use the CATL batteries, this could support Subaru’s just under and hour claim to fast charge. CATL website also has some interesting info on the battery technology they offer. Though they state their batteries can be charged to 80% SOC in only 30 minutes. So it could be that Subaru is being conservative by limiting the onboard charger to 100kW.The first Toyota EV since the “powered by Tesla” RAV4 EV plays well to Toyota strengths, with top efficiency and a thoughtful feature set.www.greencarreports.com

For the 'Panasonic' battery options Toyota has in the two-wheel drive vehicles, it's not just Panasonic. Prime Planet Energy & Solutions (PPES) is a joint venture between Toyota (51%) and Panasonic (49%) started in late 2017. Toyota have had years to work first-hand with that technology, they're confident in starting with their own co-developed tech hitting the ground running. With the CATL packs, the Chinese company (as Nko029 says) states it can handle that level of charge. Toyota (and by association Subaru) are taking it in steps. I'm fine with that.
The VW I mentioned at the start of the post? Their batteries were produced by South Korea’s LG Chem. But once ID 4 production shifts to Chattanooga, Tennessee this year, the batteries will be supplied by SK Innovation, another South Korean company that recently opened a $2 billion factory nearby VW’s plant there. So they had to break in their tech too, first with LG and now with SKI, and they've been selling the ID.4 for a couple of years now. Give the Subaru time to catch up.
