BYD D1 comes with a cobalt-free BYD Blade Battery

BYD D1 comes with a cobalt-free BYD Blade Battery
BYD D1

BYD D1 is a very interesting electric MPV (Multi-Purpose Vehicle) that gets a cobalt-free LFP battery.

With a sliding door on the right and two normal doors on the left this is an electric vehicle especially made for families with kids and ride-hailing services.

Chinese ride-hailing giant Didi Chuxing, the company that bought Uber’s China business in 2016 will use this model. According to Moneyball, Didi plans to put 10.000 D1 units in service already this year – between October and December – and 100.000 units in 2021.

 

 

The specs of this electric vehicle were already made available by the Ministry of Industry and Information Technology (MIIT).

 

BYD D1 specs

  • Length: 4.390 mm
  • Width: 1.850 mm
  • Height: 1.650 mm
  • Mass: 2.015 kg
  • Curb weight: 1.640 kg
  • Max speed: 130 km/h (81 mph)
  • Range (NEDC): 418 km (260 miles)
  • Consumption (NEDC): 12,8 kWh/100 km
  • Battery energy density: 140 Wh/kg
  • Battery type: LFP BYD Blade Battery
  • Motor: 100 kW with 180 N.m of torque

 

In a more realistic test cycle such as the WLTP, the range would be around 310 km (193 miles) and the consumption around 17 kWh/100 km.

While not mentioned in MIIT’s website, the battery capacity seems to be 47,5 kWh as shown in the slide below.

BYD unveils the volumetric and gravimetric cell-to-pack ratio of the new battery packs

 

Let’s do the math.

  • Consumption: 12,8 kWh/100 km (this includes charging losses)
  • Range: 418 km

 

418 km – X

100 km – 12,8 kWh

X = 418 km x 12,8 kWh / 100 km = 53,5 kWh

 

We need to consider that consumption under NEDC includes charging losses.

So we have to use 53,5 kWh from the electrical grid to completely charge the battery. If the battery is 47,5 kWh as I think, it means that the charging efficiency of the on-board charger is 89 %, which seems about right.

 

BYD D1 from different angles

 

As it was briefly discussed in the comment section of a previous article, BYD can switch to cobalt-free CTP battery packs much faster than most automakers. Mainly because it produces its own battery cells and battery packs, therefore it doesn’t have any contracts to honor with external suppliers.

Currently BYD is putting its Blade Battery packs in models that have bigger batteries, where replacing NCM with cobalt-free LFP represents more savings, but I expect that these packs will eventually come to more affordable models such as the e1 and e2 that have smaller batteries.

I think that by next year all BYD electric cars will be made with cobalt-free batteries. Then exporting electric cars to other markets such as Europe or North America can happen in full force. In the long run, BYD will eventually produce its electric cars locally in different continents.

 

Anyway, I remember the old days when the sluggish BYD e6 was the electric car aimed to serve as a taxi. This BYD D1 seems to be a much better vehicle and I hope to see it in Europe someday.

 

Which BYD model do you think that will be next to get the Blade Battery?

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

It’s chinese. Is it also covid free?

Assuming the D1 (which I didn’t even know they have) is the base model Song Max I would guess that the Song Max should be a top contender for the next blade battery roll out…

How fast do these charge? Am I correct in thinking that thermal management doesn’t matter so they can charge them as fast as you want?

Hi Alex.

We still don’t know how fast this BYD Blade Battery can charge, LiFePO4 battery cells can be optimized for energy or power density.

Below we have different LiFePO4 cells from Guoxuan.

With LiFePO4 cells you still need a good BMS and TMS, as they should be kept at low DOD (Deep of Discharge) and moderate temperatures (around 25ΒΊ C).

Cheers. Very informative.

Nice to see another BEV being launched.
Ideally they should have installed regular doors on both sides and called it a Crossover.
MPV sales are decreasing at a rapid pace in both China & Europe while crossovers are increasing.

This seems smart from BYD in order to keep up with taxi sales. I would guess many taxi companies are tired of the e6 or just never bought it because of its limitations, but this one is ideally suited for taxi service.

It’s a bit shorter than a Leaf, but is taller and a bit wider, so it’s very similar in format to the Toyota Kijang sold in Indonesia, which is a very popular taxi and private car there, even if it’s very underpowered. They squeeze 7 seats into the kijangs, but they’re still small enough to fit in urban traffic.

I hope BYD does well with these and exports them or even assembles them in other markets.

Ps- what’s with the racist comment from Sergio?

BYD recently registered an “all new” e6 with blade battery. All new is within quotation marks, because it is a slightly redesigned, 5-seat version of the Song Max.

https://www.autohome.com.cn/news/202006/1005332.html

Also Han, Tang, Song Plus and Qin Pro have blade battery versions registered.

All new e6 is a good news. e6 is probably the 1st EVs that went on sale in 2009 itself. Finally a redesign with a better battery and this should be the vehicle that Taxis buy.
D1 will just be confusing with such doors and will flop just like Hyundai Veloster that sells poorly in USA.

I’m not sure, that roll back door makes it easier for taxi customers to get in and out of the back seat doesn’t it?

Cool, thanks. The new e6 is a bit bigger than the D1, and maybe more practical as a family vehicle, so maybe it is more intended for the personal car market rather than taxi service?

Glad to hear that BYD is not wasting any time with taking advantage of its blade battery.

The new e6 is probably for the taxi market only, there isn’t any communication from BYD about it. It might even be a temporary badge for registration purposes only, the commercial name is irrelevant in the Chinese approval system. A couple of years ago BYD registered an e6-badged Qin Pro. That car was never sold as such to the general public, but was probably a taxi version only.

Thanks for the heads up Leo.

The BYD e6 currently has a 82 kWh battery that weights 700 kg (117 Wh/kg).

The BYD Han EV has a 77 kWh battery that weighs roughly 550 kg (140 Wh/kg).

If the new BYD e6 adopts the same pack, it gets a battery that’s 150 kg lighter.

However, BYD seems to have improved the weight by a larger amount.

Old BYD e6: 2.420 kg
New BYD e6: 1.930 kg (490 kg lighter)

Being 490 kg lighter and more efficient compensates the capacity reduction from 82 to 77 kWh.

The BYD e6 always was a heavy and inefficient electric car.

The more LFP passenger EVs, the better. Thanks for this update Pedro.
