You could try wall socket electricity counter to see how much exactly goes in to the ecoflow from 0%°]

[James_Ryan]

15:41 300Wh loss is very plausable because the inverters dissipate 300W of heat (85% efficient), so charging for 1 hour and including losses from other electronics and fans = at least 300Wh loss

[virtualmartijn]

Making stuff rapidgate. It's a skill. Seriously: car makers should hire you for consulting and stress testing this stuff.

[nakfan]

Almost everything turns out interesting when Bjørn gets involved 👍

The ecoflow was reporting dc power out, so just multiply that by the elapsed time while charging. It appeared to show around 2.3 kw dc output for 2 kw delivered.

[steveanderson]

Loved that high speed commentary moment! Your sense of humour is spot on!

[darekmistrz]

Can You do same charging test but on 5A? I think the losses will be smaller and Ecoflow will not overheat.

[Bigs]

Good design that it runs into thermal protection when charging (which is usually not critical) but not when discharging (which could be a life or death situation).

[silverstoned]

Add a few solar panels to that setup and you reduce/eliminate the load on the battery. In ideal sunny conditions, you can harvest +4 kWh. I have a DIY setup using Victron components with a 7 kWh prismatic battery pack and can generate about 5-7 kWh with three 330w panels in series. This equates to about 25-30 miles of range per day between my two EV’s, whichever is home.

@bjornnyland
question for the 0% tests or in general. If you plugin solar to Ecoflow and put the modules on roof of the car or on the side (for best angle depending on where the sun is). 1. Would you get more than 2.3kW power to charge from Ecoflow? 2. How long would the solar prolongue the charge of the car (Ecoflow normally drained in <1h).

[cypercharged]

ScanMyTesla shows only one decimal for usable remaining. Below 10.0 kWh it shows a second decimal which is always zero (9.90 kWh, then 9.80 etc…)

[MrProooosit]

That’s the name of your shuko charging cable? I have EcoFlow delta Max and one 2kw extend battery but my charging cable report Earth error. So need same charging cable you have.

[Rothammel]

5:30 @Björn the cable tells the onboard charger only 10A, the actual current determines the charger in the car

[OriginalThisAndThat]

I have EURO (Schuko) version of Ecoflow Delta Pro 3, 6kWh unit. Tried it with Tesla's mobile charger, but it was blinking two red flashes which indicates ground problem. Tested mobile charger in wall socket and it was ok, all green. I have no clue whats wrong. 6:33 7 cups of black coffee before making the video.. X-boost increases wattage when lowering voltage.

[georgepelton]

The EcoFlow has losses in its DC-AC inverter, as well as the power required to run its internal fans. 300 Wh total loss from a 2000 Wh battery would be 85% efficiency. I would expect about 90% from just the inverter. Add in the fans, and 85% seems about what is to be expected.

[manukahoney]

Is there also a battery model with type 2 plug available (instead of schuko only)?

[benoit]

The voltage drops at the end of the cable due to the Joule effect, which is linked to the circulation of current in a medium that has a certain resistance, depending on its size and nature. This voltage drop materializes the energetic losses in line. There are also losses related to the operation of the various devices that are in the loop, and those due to the internal resistance of the battery.
Generally speaking, the more current there is in circulation, the more heating and losses there are. That's why accelerating or regenerating brutally heats up the battery and consumes more current than driving quietly with a light foot. It is the same for the recharge: low power = low losses.

[Blasterxp]

10 km from a battery bank isn't bad. I think the 2333watt in the ecoflow is before inverter (so reall power out of the pack). From charge calble to tesla pack seems okay? Onlu think: when Car AC kicks on; the battery charge is used again...
Wish to see the efficiency from internal AC charger.
Charging at home, what amps has the less loss?

[georgepelton]

In Great Britain and other RHD countries, maybe the right side is the right side and the left side is the wrong side, based on Bjørn’s logic that it is more convenient to be on the driver’s side.

[davidrunnalls]

Agree with you about charge ports for left hand drive cars / countries, but in the UK the opposite is true, what about when you are in
Thailand? Another good informative video.
