Nebukadneza | huu … lemme try to do that math, sec | 12:09:56 |
Nebukadneza | ah, that’d be about 18.5kWh/100km, right? | 12:15:27 |
stevieh4130 | Sounds about right. It’s significantly better in summer. | 12:16:22 |
Nebukadneza | with ~ 0-8°C here, mostly damp/slightly wet roads, i’m at somewhere around 17.5-18kWh / 100km (which, i think, works down to ~3.65 miles / kWh) | 12:16:23 |
Nebukadneza | quite similar | 12:16:33 |
Nebukadneza | heatpump here, btw … works like a charm above 0°C, but below it doesn’t seem too efficient | 12:16:49 |
stevieh4130 | Yh, both cars are fairly light considering their batteries. | 12:17:08 |
Nebukadneza | luckily though — i really don’t understand that trend of building these super heavy cars at all ☹️ | 12:17:30 |
stevieh4130 | Interesting on the below zero. | 12:17:39 |
stevieh4130 | Me neither. Just means a huge pack and more weight. | 12:18:04 |
Nebukadneza | yeah, i think the theoretical design-point is that it can do something useful down to a much lower temperature, but … afaik, below -5°C, it’ll start up resistor heating elements to support the heatpump | 12:18:46 |
stevieh4130 | Which isn’t good. Kinda makes it a bit pointless 😳 | 12:19:32 |
Nebukadneza | mh, not sure | 12:19:39 |
Nebukadneza | i mean, you do have a heatpump too — one that’s designed to only cool, i.e., only work in one direction | 12:19:53 |
Nebukadneza | 's called an AC 😅 | 12:20:04 |
Nebukadneza | and … assumption on my side here … i think that a heatpump will only get so much bigger/heavier when adding bidirectional capabilities, it probably makes sense to carry that little extra weight to have efficiency gains when the outside temperature is a range where it can be more efficient | 12:24:29 |
stevieh4130 | Agreed. Just disappointing that it has less effect when you really need it below zero. I’d much rather have one than not 😀 | 12:42:49 |
stevieh4130 | So I’m guessing your in Norway? Just guessed by your username and from watching Bjorn Nyland YouTube videos 😎 | 12:47:18 |
Nebukadneza | haha … not really — southern germany | 14:28:19 |
Nebukadneza | i mean — as long as its not absolute zero at 0K, there is theoretically energy to be harvested from the air xd | 14:29:08 |
Nebukadneza | btw, do you care about battery "conservation"? if so … whats your everyday strategy? | 14:29:47 |

Nebukadneza | stevieh4130: Just have some interesting test data | 14:19:50 |

Nebukadneza | I'm just standing still somewhere and have to wait in car, with heating on | 14:20:40 |
Nebukadneza | It's on full heat pump mode, while heating up to 20°C using ~1600-1800W | 14:21:24 |
Nebukadneza | After reaching setpoint it spins down the compressor and is at ~600-1000W | 14:21:56 |
Nebukadneza | And pretty much stays there | 14:22:44 |

Nebukadneza | You know what's nice? | 11:15:05 |
