Seal U DM-i owners - what’s your real EV range?

This topic could become interesting. I'm still waiting for my boost trim to arrive, but I'm already worried now..

I have exactly Boost trim :) but this is literally my first ever EV experience. Maybe it's me, not the car.

I normally drive in the highway to work. Keeping at a pretty constant pace, I can make 60km and still have around 30-35% of the EV charge. If I try to go a little bit faster, with more acceleration, I normally end with 25% battery. So, that means that theoretical range is around 80 km. But because the gasoline motor turns on at 25%, de facto is more like 60-65

The seller told me it's for people who, for any reason, don't want to go full EV and it's meant to reduce fuel consumption. He also suggested to plug in the car whenever you can at home since the battery can handle it. Set the driving mode to HEV and forget. EV is just there because it can, but doesn't make sense with this car. Anyways,... I still have to wait 3 weeks to experience it.

You have a boost or comfort model? The boost trim has a range of 80km here in Belgium (WLTP), comfort is 125km EV range. 1. Where are you located? Cold, mild or warmer climate? 2. Is the climate control in eco mode? 3. Summer or winter tyres? 4. Tyres properly inflated?

Forgot to add my consumption https://preview.redd.it/dysfbv0s9spg1.jpeg?width=1037&format=pjpg&auto=webp&s=ff6675647da1aca50c32e1d5a9eceeb33e0cd330

Boost. As per BYD brochure, city EV range is 80km, mixed EV range is 115km. I guess WLTP is just useless. * Poland, mild currently, around 10c * Climate is in Auto mode, never knew there's eco mode, will check * Summer tires * 2.5 bar, as suggested by BYD https://preview.redd.it/tj74ogjlaspg1.png?width=1718&format=png&auto=webp&s=ebf4dabc7eb4268ecbee9b5ad96147b5fc223840

wow I would love to get those numbers haha. but it's impossible to get a steady speed in city. there are always traffic, traffic lights, a lot of full stops etc. it's weird that BYD provides such a high range estimate for city cycle specifically, like they don't know how city driving looks like?

interesting. what is your typical daily drive? 10km? 50km? maybe it's the driving distance that makes the difference.

Hmm never noticed they mentioned city and mixed. A quick google search tells me that city consumption is speeds up to 50/55 km/h, so quite slow. The average speed to reach that city consumption is probably a lot lower too. 10 degrees still lets the climate control work hard, I only notice a reduction in consumption above 15C, even better at 20+. Check the climate control settings for an eco mode (instead of comfort), that will reduce consumption even more. I rarely drive with climate in comfort, even on longer trips it stays in eco, only at 22C.

I disagree completely with what the seller said. I keep it on EV for my daily usage, and I only use the gasoline motor for longer drives. The electric motor is the strongest one, the gasoline is the auxiliary. Of course you can keep it in HEV mode and have a satisfactory experience, but this statement "is meant to reduce fuel consumption" makes no sense, as it assumes that the electric motor is an auxiliary one

For some reason your app shows you HP/h instead kW/h. Maybe in car settings you also have set different measurement values. This is why its differs. I own comfort trim (125km) and its pretty accurate maximum that I get its 150km from (100-20% SoC and car doesn't allow you discharge any lower). But I live in Spain and in my city max speeds are 50 km/h but mostly 30 and 40. Also I use Eco for driving mode (its only make difference on speed up curve, I like more comfy starts/stops). Also AC (heat pump) in winter consumes x3 energy from summer usage so that may be the case for you.

Yeah, in general electric motors work quite efficiently in the 50-70 km/h range, I get why they give a longer number for city driving. Maybe if there is s lot of terrain elevation in the city, or s lot of braking and sudden accelerations, that eats the battery

Mostly commuting 25km one way, 80% highway at around 100km/h because of the speed limits

do you charge at home daily or use public chargers? how do you keep the battery full for every day EV driving?

maybe that's a weird translation of units. will try the eco drive mode though

that explains your numbers, thanks!

EV range will decrease in cold weather due to the lower temperature slowing the chemical reactions in the battery. This is normal . Over the last Volvo and Audi PHEVs I’ve had, I’ve noticed range will decrease by up to 25-30% below 10°C. Also AC, heating and seat/steering wheel heating consume a surprisingly large lump of charge. You can see a fairly detailed breakdown of which car systems are consuming battery energy in the car settings via infotainment

Yeah, and it is steady, but not particularly slow. I can be driving at 100-120 km/h for long stretches, and that speed is supposed to be less efficient... One silly think I have noticed that gives me a little bit of extra range is that I let the car "fall" in downhill stretches. With a gasoline car pressing the gas pedal in a downhill stretch might be the difference between no/idle consumption and a negligible consumption. In the byd, it can be the difference between 2-5 kw of consumption and -15 KW of recharge. Mind you, this only works for steep downhills in which the car can kinda maintain the speed.

I charge at home at night, as the price of electricity is lower then. I did the calculations and 100 km is 1.5-2 euros in electricity for me

Interesting point of view. This seems logical if you explain it that way. EV for local drives, HEV for long trips. I like that.

yeah, home charging is perfect in this case!

Design owner here. Driving in small town with speeds fom 50 to 60 km/h. Range is as low as 40km in winter to up to 65km when driving in warmer weather like an old person, but most of the time 50ish km

yeah I guess it's true for all of us - small towners :) I believe it's mostly because of shorter distances. however I switched A/C to eco today and will try to drive next couple of days in eco mode instead of normal. maybe range will get at least somewhat better.
