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.
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.
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?
