Electric Vehicles

The article below is aimed at electric vehicles but most of it applies pretty well to the Li-on home ESSs that many of us use. One point not clarified: does the replacement cost include trading in your old batteries, or are you at liberty to keep them and re-purpose the cells? Given the low usage of electric vehicles in SA, and that the article is written about the Australian market, any thoughts @Coulomb? How much does it cost to replace the batteries in electric vehicles? (thedriven.io)

I'm planning to buy a new car: Hybrid plug-in. My solar panels produce enough power during summer time to charge the car's battery after noon. All the chargers i found rely on the red connection: If it detects power going to the red it will re-direct it to the car. As i do not have a red connection (island) ... how could that problem be solved? Red = Car? Theoretically i could use the SOC: IF at 100% then car charger ON. The problem with this would be that the SOC falls as soon as the load changes. Means, after a few minutes the SOC will be down to 98...95 indicating to stop charging the car, go back to charging the batteries. We call this a jo-jo e…

Not sure who has come across this on Supersport? Second round on today and is a very interesting format with some big racing names involved. A electric racing SUV with a difference, amazing how they throw them around and how they perform. The have a 40kw usable battery developed by Williams Advanced Systems. Just thought this would be of interest for some forum members!

Hi all. Desperately trying to find a forum where I can get some help with an electric quad issue. Hoping this is the place. I have issues with the power on my kids 36v quad. It's been in the garage for a while and when I brought it out, it wouldn't work. Did a bit of electric testing a realised the barrel ignition needed replacing due to a connection issue. Apart from that the 3 batteries appear to be pushing out 36v, the motor turns under no load, the throttle seems to work, lights all working, forward and reverse working and the two speed setting ok. The issue is when there is any load on the bike, it doesn't move. I've checked the power cable going to the motor…

I also look with interest as to how EVs are developing. However we do need to know where we stand currently and here is the situation: https://www.economist.com/graphic-detail/2019/11/07/what-does-your-car-run-on

Out of curiosity for those with EVs, what licence fees are you charged? Are they the same as an equivalent normal vehicle? A lot of govt revenue comes from fuel taxes, have they thought about what will happen when more electric vehicles are on the road and they are no longer getting fuel levy? Also if Eskom wasn't so pathetic, they would surely be embracing and encouraging electric vehicles, as this would provide a new revenue stream. Imagine Eskom branded fast charging stations.

Maybe the time has come to create a new forum major topic (not sure how you describe it) for Electric Vehicle Discussion. Just a suggestion. Sent from my SM-G920F using Tapatalk

Just received a Whatsapp with this link, Did not have time to check the maths, but looks interesting. He is bringing 28 in, and only 20 left. https://shop.bitmart.co.za/product/bitmart-m5/ Sadly I need to go on a serious diet before i can play with one of these 🙄

Morning, So after a few years of using my Land Cruiser as a daily driver I decided to bite the bullet on a electric car. I have chosen the BMW i3 REX It has a 22KW (18.8KW usable) 60Ah Lithium battery giving you a range of 130-160km (200km in ECO PRO + mode) and with the REX (Petrol range extender) you get 260-290km I got the model with all the drive assist options, so it has active cruiser control and can drive itself in traffic upto 60KM/h I ran the battery to 6% yesterday as a test. Drove 157km. Used 18kw to charge. At the peak price of 0.81c per KW, it cost R15. That is 1.1L of petrol equivalent or 0.7L per 100km I am chuffed. As a…

Took the plunge and bought a BMW i3 94Ah Rex today. The special BMW Centenary deal was too good to pass over. Man maths won the day. Sent from my SM-G920F using Tapatalk

Nissan claims Tesla got it all wrong - I'd be tempted to agree although Tesla don't seem to get too much wrong too often...... https://thedriven.io/2019/07/11/nissan-sees-leaf-as-home-energy-source-says-tesla-big-battery-waste-of-resources/

It was mooted that Powerforum chaps enter the Sasol Solar Challenge 2018. After some discussion it seems 4 sponsored cars will be available for tech groups to race. The Hungarian team have made the mould of their 2016 car available for this purpose. At this stage I cannot participate but I can perhaps assist in getting the right people to talk to @Energy or some nominated big cheese. I am sure something like this would be a blast but the team would have to be dedicated and team members would need to put in a serious amount of time and perhaps even a bit of Tom. The motors cost R250k and there are 4 of them. Panels are expensive as the cells for the 4m2 panels that ea…

From a post by Winstone Jordaan - owner of the Sasol Solar Rally. We have all heard commitments for Zero emissions by 2040. That seems such a long way away, so let's unpack this. Firstly 2040 is the country targets, like France, Germany, UK, etc. However for the cities, like Paris, London, Amsterdam, etc. this is more urgent, so they are typically setting the zero emission targets in the cities for 2030. Still a bit in the future. Consider this, a fossil fuel car in 2030 in Paris, would be worth Nothing...., possibly as soon as 2028, in fact may be worth -1000 euros, the cost to recycle it... Since people typically drive a car for 5 to 7 years. This means that anyone…

A man will travel from India to the UK using a self-built solar electric vehicle. He wants to spread awareness about green transportation. This electric vehicle can run 80 km when charged for 8 hours and 25 Km when exposed to the sunlight for 5 hours. The total distance travelled will be 10000 km.
