NexPower V3 hybrid battery unveil - Sodium-ion battery

The BYD Dolphin, and yes it sells for ~$13.5k in China, and ~$28k in Europe, and ~$21k in Mexico. There's been a few test mules for them up in Michigan, presumably something to do with Ford's Skunkworks cheap EV team Farley has been talking about. The price is much lower in China due to no import tariffs (obviously), and very very high EV subsidies.

 

Why then does the plug-in Prius consume more fuel when the battery is low than a regular Prius? It has a bigger battery. It may not be more efficient, but it is slightly worse in terms of performance, both in the city and on the highway.
Oh no, the damn law of conservation of energy.

 

because a larger heavier battery requires more fuel from the engine to drive under the additional load...

 

Too much social media has taught me to no longer care about wanting to know "what an M2 or Dolphin is" but I'll have to admit I am sorta curious? Are those the names of BYD cars?

 

From what I've read, daily driving habits in these plugins have far more influence over the motor-battery vs. ICE interaction than in regular Prius.

 

Interesting. My understanding was that NexPower was approaching 10k packs.

 

Can't wait to test this claim out on the bench.

Your units don't work. I assume you're saying you have a capacitor large enough to source all the energy required to charge the pack from empty to full in a few seconds? If so, you're going to need a REALLY large capacitor. The derivation below gives every benefit of the doubt to your claim:
-assuming charging pack from empty to full consumes 450 Wh, which is ~1.6 MJ.
-assuming the average pack voltage from empty to full is 220 VDC.
-then you'd need a 120 farad, 450 volt capacitor (1.6 MJ * 4 = 0.5 * C * (220/.67)^2).
-For reference, a 2 mF, 450 volt capacitor is about the size of a can of coke. You'd need QTY60000 of these capacitors, which would consume 14 cubic feet of volume. For reference, that's the same volume as QTY4 typical backyard swimming pools.

We could certainly get the size down by switching to super capacitors, but of course their instantaneous current delivery is going to be too small.

The real takeaway here is just how much energy we can cram into chemical reactions, compared to charged plates.

Regarding the various posts saying "More Ah means more MPG", the only compelling argument I've read so far is those who drive up and down steep enough mountains that the smaller pack would fully empty/charge when going up/down. Otherwise, without a PHEV option that charges from the grid, all the energy ultimately comes from gas... area under the curve (i.e. energy) makes it essentially irrelevant how fast you charge the battery (within reason).

I know I'm late to the party, but this is a planned feature in my LiBSU product... my existing Honda Insight product (LiBCM) already has this functionality implemented and working without issue for several years now.

This is a key long term benefit for team sodium. Still too new for my taste, but someone has to early adopt it.

I know of one person who experienced a thermal event without the Signal Soother installed. The SS only makes it twice as likely to happen... odds are still fair without SS present.
