Electric car thread

Not quite a conversion on the road to Damascus, but it looks like I'll be taking my first ride in an EV next week. My son has bought a BYD Shark 6 for himself

and a BYD Sealion for the family car.

 

My son has a business pimping up 4WDs. He worked out plans to do what he wants to his Shark and has had initial talks with the sellers of BYDs, interesting them in his idea. If his talks produce anything, his business will contract to do up these cars as special vehicles, which will add something special to retailer's offerings. 

 

From what he says, he thinks he will be starting limited production around Spring. As well as doing this stuff with BYDs, he will still be doing similar work on the usual suspects.

 

It's good to see a young man (geez! He's 36!!) having a go. I can only wish him success. However, no matter how successful he becomes in business, he'll still be my dickhead of a son.

Just on another EV related topic. BYD recently announced that development of Sodium phosphate batteries has proved successful and that BYD is moving towards full production of this type of enegery storage. I think that the main advantages of sodium phosphate technology is a lower cost of raw materials and the elimination of the fire risks associated with lithium batteries.

 

BYD knows about economies of scale. Sodium phosphate batteries can only become the universal standard if the majority of manufacturers are using them. To get this change started industry-wide, BYD has apparently not patented the process, but is freelky sharing the knowledge with everyone who makes batteries. 

 

We shall see what we shall see.

You will Love the test drive IF you allow yourself to. The Shark rides Beautifully. It HAS to be the way of the future. Gradually but surely.. Nev

It is a truck so it's not an SUV, but the suspension is really good. Nev

Since it wil be my son's family coming up for the funeral, it will most likely be the Sealion that I will drive. It's funny, but the thing that I want to test is how the vehicle decelerates from 100 kph to 80 kph. I have found just where to take my foot off as I approach the 80 zone at the edge of town and slow to 80 as I reach the speed sign. Similarly, I know where to back off from 100 as I approach my driveway.

I think you'll cope. The less brake you use, the more electro regeneration but use the Brakes IF you have to like anything else. Some people consistently use less fuel than others do by thinking about how to  and applying it. Nev

My EV has 4 levels or regenerative braking. 1 is a bit like a normal ICE car, 3 is like applying brakes moderately & OPD (one pedal driving)

is adaptive based on how you take your foot off the accelerator. Take it of suddenly and it brakes very quickly & slower if you take your foot off slower. I use the brakes occasionally to stop the discs from rusting and becoming pitted. I know of a Tesla that had done nearly 700,000 km & went in for new tyres & they checked the disc pads & found them less that 30% worn.

Sodium Ion batteries have started to appear in a number of Chinese EVs. Battery cost is around 60-65% less but energy density is considerably lower at this stage of development though those using Sodium Vanadium phosphate have a much improved energy density but higher cost. CATL the worlds largest battery manufacturer is producing them under the Naxtra brand. Their big advantage is high output under harsh conditions from -40 to +70 degrees celsius
