    Electric Vehicle issues

    in Tech Talk

    Posted

    Sounds unlikely that a 6V would get up to >13V.  If it was 12V (or you were somehow measuring two) then 11.8V unloaded sounds pretty bad, which could explain your issues.

    Just spitballing, but if it can drive but not produce much torque then:

    • it's in limp mode because its detected a dud cell and doesn't want to blow it up
    • a dud cell has high internal resistance which is reducing current (since it sounds like all the batteries are in series)
    • anything else that will put it in limp mode (At least on a Tesla, there are 50 million reasons, but most common reasons are being in a minor crash, losing coolant from the battery pack, any of the stability/traction systems freaking out, losing coms to one motor)

    The other thing I notice, is that I am so much less competitive when it comes to drive when using autopilot in a Tesla. I don't care if the guy in front of me is doing 97 or 100, because I don't have to change anything. I can just chill and pay more attention to the podcast or whatever else I'm listening to.

    After living in the Netherlands (Amsterdam) for over a year, and San Francisco before that, here is my essay:

    There is a big difference here between commuter cycling, and recreational cycling. In the Netherlands we have recreational cyclists who

    • Bike is usually $500 or more (both road bikes and mountain bikes are popular)
    • Wear sporty clothing
    • wear helmets
    • Cycle faster

    For everyone else cycling is just a easy way of getting around

    • Its cheaper than public transport, because most bikes are <$100 or less (I paid $35 for my city bike, although I have a fancier road bike too)
    • Maximum convenience (no change of clothing, no helmet)
    • Cycle at a moderate pace, not enough to get you sweaty (although keep in mind there are no hills here). Reduces severity of accidents when they happen.
    • If you have a slightly longer route, you get an electric bike, or a small scooter (<2kw,  with electric variants too). The small scooters are allowed to use the bicycle lanes, which takes away all the fear of being on a scooter. They make up about 10-20% of the cycle traffic. Compared to owning a car, the impact of a scooter is so much less with regards to parking, noise, space etc. You fit panniers for your shopping. You don't need a helmet for these, but maybe 50% of people wear one anyway on a scooter. If you are old, or have balance issues, you can get these tiny car things (2 person, but half the size of a small smart car) that you can also use on the cycle lanes and park anywhere.
       

    These two categories rarely mix, all the sport cycling is done outside of the city, everyone in the city is just cruising around.

    Because bikes are cheap, this also means I can have multiple bikes in different cities. For example, if I was catching the train from Papakura to the CBD, I could cycle to the train station, hop on the train, and then cycle to the office. Total investment <$100. This is a pretty common thing for people to do. 

    You are hardly ever interacting with cars on the road. You have cycle lanes (with a height separation) on all but the smallest streets. The ones without cycle lanes, they are usually cobbled so cars area going slow.

    Public transport here is good, but cycling is always faster and cheaper for 90% of trips unless you are travelling large distances (15km or more, or between cities). This is mostly because the cities are so compact. You don't need a big lawn in Amsterdam, because everyone has a park/canal/forrest that is 5 min walk away that you can go and chill, drink a beer at. People who want more space, hire workshops/gardens (yes, you can hire garden spots to cultivate) on the outskirts of town, which would be 15-20 min away.

    If you need to go to IKEA to get some furniture, or want to go hiking in the forrest far away, they have really cheap car hire schemes ($2-2.50 per hour, or $20 per day). If course I just borrow a Tesla :) . There are also box bikes for dragging the kids and shopping around.

    Most of the hassle with owning a car here is parking, and that driving around the cities is super slow. Plenty of people have them in the outskirts, but they would still cycle within their township, and only use it to go to other cities.

    Cars are pretty much always at fault in the Netherlands if involved in an accident. It's kinda the same as powered gives way to non-powered when boating. 

    It hasn't been this way forever in the Netherlands. The Netherlands was very car-centric after WWII, the cycle infrastructure is from the last 40-odd years. See this vid for details

    Ask @Llama if he can submit a request to have the Jetsons noise added to all Teslas.

    Might not be much further away than you think.

    Lots of new legislation floating about that we might have to comply with to make a certain amount of noise in urban areas below certain speeds. We already have to do it for HK.

    Somewhat unrelated, but its been very interesting driving around in a Tesla, because it gives you instant kWh/mile and projected range based on your current driving. A couple of times I've been caught out without enough range to get to the next supercharger (dat range anxiety), but managed to get there by driving extremely smoothly and turning off the AC, lowering the suspension and stuff like that. People have competitions to see how much range they can get out of a Tesla, I think the record is a ~2x increase in range over the EPA rated range (885km from an expected 430km, and that was only using 90% of the charge), by driving a constant 45km/h or something. I was surprised how much your speed affects your consumption.

     

    Also, I'm Dutch, and the Netherlands is planning on banning imports of consumer petrol and diesel vehicles in 2025.

    Aquired Honda Hornet (600cc version). Did not quite realise that they have 100+ ponies inside that engine. Takes a bit of getting used to after the CB200. Still, nice having working breaks, heated grips, and an engine that starts first go.
