    Good day to you all.

    I've let this run a bit before I thought I'd comment.

    Solareff acquired a 75% stake in GridCars from 1 September 2017. The balance is still held by Winstone Jordaan (the founder of GridCars and the Sasol Solar Challenge).

    During the last year we've kicked around and brainstormed a lot about very much the matters raised in the first 20 posts.

    It was all about the chicken and egg. When by brother (and business partner) bought an i3 for his daily use in and around Gauteng last year, I couldn't follow suit as there was no way to reach Cape Town (even from Mossel Bay) with a 200km range on an i3 without a fast charger along the route. Hence we took the bow with GridCars and decided to invest and build the highway with appropriate partners (Jaguar for the present round).

    In due course we'll have many conversations on this and other forums about the pros and cons of EVs but let me start with perhaps three considerations:

    1. GridCars also manages the backend software of the charging infrastructure. We'll be able to carefully manage the roll-out of more charge points as we determine the need from actual volume and EV travel data. So we'll know which route and at which kilometre mark a need arises.

    2. Each site is assessed to determine what infrastructure is available - the basics of this is a large enough surplus power supply (82kVA) and somewhere where you could spend 30-45 minutes whilst charging as opposed to a current 10-15 minute fossil fuel refill. (essentially you'll in future stop for a watering closet, coffee and a muffin as opposed to only grabbing the former two). And soon we'll add to the infrastructure by supplying these sites with Solar PV systems.

    3. In the near future your car battery would also be your home battery! In a typical day you'll charge your car from the solar panels installed at your office rooftop, drive home and reach home with a battery at 75% charge, plug your home into your car and use the energy in the car battery to power your home during the peak evening hours (when you're on a Time-Of-Use tariff), start charging your car at 21h00 from the off-peak TOU tariff and drive to work in the morning to repeat the cycle. This will reduce the pressure on the grid also and make your car even more cost effective. What a waste is it when your current Hilux is parked with a full LR tank in the garage that you couldn't use to run your TV?

    These are some of the teasers but there's many more exciting ideas that would follow.

    WELCOME TO THE SASOL SOLAR CHALLENGE
    The Sasol Solar Challenge is a biennial competition. Teams from across the world design and build solar-powered vehicles to drive across South Africa in an eight day event.
    The journey starts in Pretoria on 22 September, and in 2018 more than 20 local and international solar cars are expected to participate.
    The teams will compete to cover the most distance, following a set route each day, and then completing additional loops with the power they have left. It takes good engineering, great drivers and a team that manages energy, the weather and the routes well. The many returning teams will be aiming to break 2016’s records of more than 4 5000 km. Combined, the convoys are expected to cover more than 30 000 km using only the sun’s power.


    The finish line is in Stellenbosch, and the awards ceremony takes place in Cape Town on 30 September 2018.

    Some interesting stuff. Especially point three. A whole bunch of challenges.

    At what price points and factors does round tripping a battery make sense instead of grid.
    By the time this makes sense EV's will probably be becoming mainstream.
    Who pays for the Capex for the companies charging infrastructure.
    Very few company rooftops will be able to charge a staff parking lot of EV's.
    What happens in bad weather, does the company draw off grid.

    This would be big business for Solar PV suppliers. In fact it’s going to be. I suspect there will be some clever hybrid generation solutions coming from people like you.

    ———————

    Funny thing is. That Hilux parked in the garage with a LR tank would be a much more efficient way of running your TV. Not green, or renewable, but efficient.

    wow, THERE GOES THE THEORY.

    expensive to buy, expensive to charge, range is an issue, sounds like a washing machine

    @Fluffy - It will be a transition. First there'll only be one or two cars in the car park, later there'll be a 100 but by then we'll have large scale storage and be able to wheel power from Solar Plants built at the edge of the city. I do a lot of study, presentation and work on the grid of the future so it won't happen overnight but soon enough for us all to experience.

    @Freelander2 - Only your first statement is correct at the moment. The Ipace, TeslaX, Audi Etron all sells for the region of $70,000. But hold you horses - the likes of Hyundai and Kia are coming over the horizon at the speed of ....... well electricity.
    As for the last two you need to run the numbers.
    An i3 for example uses 13kWh/100km. At R3/kWh that comes to R39.00. R39.00 buys you 2.5l of petrol. How far can you drive on 2.5l of fuel with your average performance hatch?
    Range anxiety is exactly what we have now quashed by installing charge points within the range of these vehicles - Even an i3 can charge every 200km and the new models comes with far more range.

    So here's what'll happen - you'll learn to drive long distances better rested as you'll spend 30 - 45 minutes at each stop charging your car. In addition you'll have saved R75.00 for every R100.00 you would have spent on fuel. So people will be more relaxed, less aggressive and have more money to spend on other important things.

    Back in time when the Joule was under development, I attended the International Battery conference hoste by CSIR in Cape Town.
    Battery development is one of the areas where an immense amount of research is doen. Think further than vehicle batteries - cell, laptop, endless list.
    The idea with the Joule was that Charging stations would be set up on routes - but with a battery swap out system available as well.
    I dont recall all the ins and outs - but the battery swapping system would have worked not unlike gas bottels - dont dont really own it.
    No need to wait for a charge - swap and drive.

    In my life I will NEVER have an electric car ever again. So here's my story...
    We had a Nissan Leaf in Pommyville. The range was 80miles claimed. The reality was about 50-60miles if the wife drove and she goes gahle!! The reality of picking me up at the airport every week was, kids in the car 10pm with blankets so they could keep warm, you dont use high beam, you dont use wipers.... The airport was 50mile roundtrip....

    So the charging network in the in-car gps shows station X ten miles ahead. You get there and there is nothing.... or half of what there should be, or stolen,,,..... or you are number 5.......or the charging point is broken.... or the wind blows in thew wrong direction and chews 20% more battery... or there is traffic and you chew more battery. It was a mess. The thing was useless. If we dropped the kids at school and picked them up again, happy days as it was 5miles one way so you could do something with it but you will have never in your life nipped so much whilst driving cause once you're flat....you're FLAT!!

    Good morning Faraway.

    Indeed you would have been hit with the same issues (range, wind, efficiency) if you were the internal combustion engine (fossil fuel) pioneers in the early 1900s. I respect you for having invested before the big wave of EV. Just a pity it did not suit your lifestyle at the time.

    You don't say how long ago this was - is this still the case for the increased number of UK buyers of vehicles other than the Leaf? If not you must be getting EVs for big bargains in the UK.

    We had the car on lease. The do very good deals here. We got it June 2015 and lease period ran out June 2017. We had to put down a 3k sterling deposit and had the car for 190 gbp per month. New the car is /was retailing for 31k! (yes it was brand new). The reason we leased was after x amount of years (5 I think), the battery bank needs replacing. That was up words of 5 or 8k if I remember correctly... it killed the option of owning it outright. We had a good solar system at home so charging cost nothing at the time. Also no road tax for electric vehicles.

    I read an article on EV that gave me some food for thought. The following are a few of the points which was raised:

    Pollution - pollution is simply moved from the highways to the generating plants. By the way, Mpumalanga has the dirtiest air in the world because of all the coal burning generating plants.

    Manufacturing of batteries - apparently the mining and manufacturing of those batteries contributes heavily towards pollution.

    Disposing of batteries - the more you use them, the shorter their lifetime. Disposing of them apparently is also a dirty business.

    Replacing batteries - apparently the second hand value of these vehicles will largely depend on the life left in the batteries, which are hellish exspensive.

    Cost of charging, charging time and availability of enough electricity at highway charging points is a challenge.

    So I had the oppurtunity to play around with one of these I-Paces. Nice CAR, its got air suspension but I'd never dare to take it offroad.

    First thing I noticed was no spare wheel. Had a look at the Range as it was fully charged at the time and it was just over 320km, I guess it increases with the regenerative braking and all the other tricks its got.

    Just playing with it while stationary chowed through 15km's of range. As a town car it should work, but untill the Infrastructure is updated, a Pretoria to Cape town trip is going to be frustrating.

    And then there's the Price, its a bit ridicoulous.
    But thats just me.

    Sure, my Defender chows petrol but I paid less than a tenth of the price for it, leaving me with more than R1,5M for petrol. I think I am still far ahead

    A relative of mine living in the UK has bought one of these cars recently 2nd hand for 19k Sterling. They are chuffed by the purchase but I understand that the man of the house drives it to work where there is a (free?) charging facility.
    But we need to keep our heads! What indeed is the case with these cars regarding the battery replacement?
    As I understand it no manufacturer/marketing outfit is making money with these EVs. They are being pushed into getting this new technology developed so it can come of age.
    How much is 19k sterling? I would love to own one of these cars but would I regret it?
    I heard they were going to provide the batteries on a leased basis so that this risk wasn't passed onto the owner.
    My fear is that with all the losses incurred down the line the end user will land up with a dog and all the promises will be out the window..
