Using Regenerative Braking To…Cook Breakfast? – Video

The chicks were in heavy shock that you could use regenerative brake

…in shock what you could do with regenerative brake

Toyota recently released a regenerative braking video (sadly of its non-plug-in hybrid race car) to demonstrate how much energy you could regenerate.

Well, regenerative braking is something common to all modern electric cars, so the topic is relevant to EVs.

According to Toyota, one lap of a Le Mans race track will result in 1.67 kWh of energy from regenerative braking.

Here is summary of the video and some added statistics from InsideEVs’ friend Brian Henderson:

“Toyota attempts to ‘amp it up’ with a hybrid race car … cooking with 1.67 kWh of electricity.
(6,000,000 Joules
… 1 lap of Le Mans race track
… 1 Joul/sec = 1 Watt)

Breakfast on 1.67 kWh
– Coffee: 171.4 cups
– Bread Toasted: 83.3 slices
– Eggs Fried: 57.7 eggs

Le Mans track
– length: 13.629 km
– avg lap takes 3.5-4 min
(not the 1 min shown in video)”

Brian notes that the average EV driver (for example, driving a Nissan LEAF) could save a similar or even larger portion of energy during a daily commute.

“A LEAF battery has an energy capacity of ~14x more kWh than was regenerated by the race car.

I’m guessing a LEAF owner likely regens more than 1.67 kWh in a typical day of driving. Now that’s something worth cheering!”

Toyota should finally build an EV, in Europe sales from LEAF are already 3 times more than Prius.

I always thought that too. The LEAF in Ireland has made 393 sales to date, whereas the Prius has only made 89. The main reason is that Toyota Europe doesn’t see it viable to offer a cheaper Prius. The only Prius here is the posh trim over €30,000, which is easily more expensive than a LEAF. They think that hybrid and especially Prius drivers just want the brand image, which is why more have got in a Lexus CT200h.

But that doesn’t mean hybrids are unpopular, and electrification in general. There are hundreds of second hand Gen II and Gen I Priuses coming from Japan and the UK (both being right-wheel sided versions). The bulk of hybrid sales also comes from the Auris Hybrid and Yaris Hybrid, this would go for much of Europe as a whole.

They can’t do that because that would make the Mirai look even more stupid.

3X times as much as the Prius? Why does Europe hate the Prius so much?

Oh I know . . . you are buying all those efficient ‘clean diesel’ cars. Ha ha ha ha ha! 🙁

Yeah, diesels roughly make 70% of new cars sold since 2009. Mainly due to the appeal of diesel costing €0.20 less than petrol on the big signs at every petrol station.

Cycling for 3 years, and developing asthma from it (now the brown inhaler every morning and night), I always knew the hidden or ignored cost of diesel.

All I can say is that when I drove the Prius in the city centre (on EV mode), there was a 2010 Audi A3 2.0 TDI that left a swirl of soot (and then some) behind it once the lights went off. Seeing the heads turn towards to the Audi, I felt rather smug how I kept up with it, silently.

They could have cooked twice as many eggs if they would have covered the pots. Oh, I forgot, Toyota makes a Hydrogen car that cant even be charged by the grid.

Great. Room now full of carbon monoxide. Nobody would sanction that. It’s too fake. The actors. The expressions. Everything. Fake. Fake. Fake!

Ah, ah!
It’s true! I don’t see any piping for exhausting gas and from that king of motor, it must be a lot and enough to choke everyone in the room fast.

Not to mention that they’d all have damaged hearing from standing so close. Le Mans cars can be loud!

Stupid commerical. Why doesn’t Toyota explain how much energy it burned through 1 lap of racing?

Plus, you don’t need much cooking energy when you are eating raw fish.

BTW, my carwingsnissan show me that I get back between 45 and 80 wH/Km of regenerative braking.
For a 100 km commute it means between 4.5 to 8 kWh of regen.
*Enjoy the simplicity of the metric system right there!

Hmmm… I’m pretty sure than an ordinary wall socket can give you more than 1.67kW.

With your ring circuits in Britain, no doubt I’m sure you can get more than 1.67 kw out of some of them because Brits ‘supplementary fuse’ their table lamps with additional fuses in the plug of the appurtenance itself. In North America, we’re usually limited to around 1.4 kw on kitchen appliances, with the exception of things like Microwaves, and Air Compressors which are allowed to go to around 1.725 kw. But even a HUGE 1 1/4 TON (15,000 BTU/hour), (i.e. has the cooling power of 2500 pounds of ice melting over a 24 hour period) room air conditioner is limited to 115 volts, 12 amps. The rationale for the difference is that, the stuff working over 12 amps is only used for a short while, whereas anything likely running for 3 hours or more, such as an air conditioner, is limited to 80% of the rating of the general purpose circuit. Now, its true that all appliance circuits are good for 20 amps in North America, but then it is assumed a multiple of appliances will be used simultaneously. An exception, so to speak, is the refrigerator circuit optionally supplied, MAY be a 15 amp circuit only, since it… Read more »
