  1. Regarding Toyota’s new 5.0 liter V8 Hydrogen ICE. The guy at EE does an excellent job of ridiculing it and explaining why you will need see it in production. https://www.facebook.com/share/v/1BRg5XGSUa/?mibextid=CTbP7E
  2. We have Onion AC chargers in central mall in Chiang Rai, they’re just typical 7 to 22 kW AC chargers.
  3. I don’t care whether use Autolife or DLT, but we should stick to only one and not bicker over the numbers. I can’t speak for other members, but what interests me is trends. How EV uptake compares to previous months and years, not in number of vehicles sold (which I find meaningless because the auto industry is on it’s knees) but as a percentage of total sales in the same category.
  4. I have an aftermarket charger with a long 10 m cable, switchable from 6 A all the way up to 16 A. It doesn’t need an earth, and if we’re going traveling to somewhere uncertain, I take that with me.
  5. Autolife are journalists, they have something in common with politicians (they don't let facts get in their way). IMHO the only official source is DLT registrations.
  6. It sounds like fraud, contact Wise directly, not through any emails you’ve had about new account numbers
  7. I'm not sure what this guy's qualifications are, but he's completely wrong. He's wrong about deterioration vs. capacity, and he's wrong about active vs. passive balancing. Tests have shown that LFP batteries cycled between low% and 25% ultimately give more power over their longer lifetime than batteries cycled (say) 75% to 100% or 50% to 100% etc. The EE video posted elsewhere covers this in detail. Most automakers use active balancers in their battery packs and I'm fairly certain BYD do for example, and I'm sure all NMC battery types do. It's more expensive but more efficient and better. MG use cheaper passive balancing (in LFP batteries) which burns off the energy as heat in higher voltage cells until it matches the lowest voltage cell. This typically only happens above 90%. Active balancing occurs during all charging & discharging. I have done a google search and cannot find a single article agreeing with what this guy says, all of them disagree with him. AI says The main difference between active and passive balancers is how they manage energy in a battery pack: Active balancers Redistribute energy between cells during charging and discharging, which can improve efficiency and increase run-time. Active balancers can adjust cell voltages faster than passive balancers. Passive balancers Dissipate excess energy from higher voltage cells during the charge cycle. Passive balancers are low cost and have a simple circuit design. However, they can only be used during the charge cycle, and they waste 100% of the balanced power as heat. Here are some other differences between active and passive balancers: Energy efficiency: Active balancers are more efficient than passive balancers because they don't waste energy as heat. Cell life: Active balancers can improve the life expectancy of cells. Balancing time: Active balancers can adjust cell voltages faster than passive balancers. Balancing conditions: Active balancers can work 24 hours a day until the pressure difference between cells is less than a set value. Cell Saviours Active Balancing vs Passive Balancing Differences - Cell Saviors says Active balancing redistributes charge among the cells in a battery pack to ensure that they all have the same state of charge with a dedicated circuit, which monitors the voltage of each cell and adjusts the charging and discharging current accordingly. Active balancing is more accurate and faster than passive balancing. On the other hand, passive balancing relies on Ohm’s Law and the natural cell and balance resistor characteristics to bring cells to the same state of charge. Passive balancing is generally less accurate and slower than active balancing and may take longer to achieve the desired result. EEPower Active and Passive Battery Pack Balancing Methods - Technical Articles says Active Cell Balancing The active cell balancing technique uses inductive charge shuttling or capacitive charge shuttling to transfer the charge between the cells. This technique is proven to be an efficient approach as it transfers energy to where the energy is needed instead of wasting it. However, this demands additional components to be added to the system which in turn translates to increased cost. Passive Cell Balancing The passive cell balancing technique uses the idea of discharging the cells through a bypass route that is mostly dissipative in nature. It is simple and easier to implement than active balancing techniques as the bypass can either be external or be integrated — keeping the system more cost-effective either way. However, since all the excess energy is dissipated as heat, battery run time is adversely impacted and is less likely to be used during discharge. Maxkgo Active vs Passive Balancing: Which is Best for Your Lithium Battery? | MAXKGO News blog says... ·Is active balancing better for electric vehicles? The answer is yes. Active balancing is generally better suited for electric vehicles (EVs). It provides a more efficient and power-saving balancing method. Active balancing is different from passive balancing. Passive balancing releases energy as heat, while active balancing moves energy between cells. This process does not generate much heat. Therefore, it can save more power. This energy-saving method is great for large battery packs in electric vehicles (EVs). The main goal for EVs is to keep the batteries healthy and extend driving time.
  8. Don't give conditions, just do it.
  9. I won't ask how it is that you know all about it in such intricate detail ..... Well buggered.
  10. More UK News as sales of used cars accelerate, EV's up massively, Hybrids up too, Petrol up marginally while diesel sales decline. Purchases of pure electric used cars have reached record levels, new figures show. Some 53,423 of the cars changed hands between July and September, the Society of Motor Manufacturers and Traders (SMMT) said. That is a surge of 57.0% compared with the same period last year, as the market share held by pure electrics rose from 1.8% to 2.7%. Sales of used hybrids and plug-in hybrids also rose, up 35.8% and 29.0% respectively. Meanwhile, 1.12 million petrol cars (up 5.7%) and 680,000 diesel cars (down 3.9%) found new owners. Sales of used electric cars reach record high
  11. Toyota seems to be finally affected by market changes. Japan's biggest car maker, Toyota, saw profits for the July-September period sliding to less than half of what they were in the same period last year. The maker of the Camry sedan and Lexus luxury models revealed that a production stoppage that followed a certification scandal and model recalls had dented sales. Toyota apologised and suspended production on a number of models after acknowledging widespread fraudulent testing, including the use of inadequate or outdated data in crash tests, as well as incorrect testing of airbag inflation. Scandal-hit car maker Toyota sees profits take a tumble
  12. It’s a sh?t hole, end of.
  13. EV sales continue to lead the industry in the UK. Data from New AutoMotive found that October was the third straight month where electric cars had more than 20 per cent of the market share as petrol sales continue to fall. In the first 10 months of the year, petrol car sales have dropped 14 per cent compared to the same period last year, while EVs took a market share of 20.8 per cent in October. It comes as separate data from the Society of Motor Manufacturers and Traders (SMMT) found that while the new car market fell by six per cent, electric vehicles provided some relief to the automotive industry. Electric car targets praised for allowing drivers to switch as diesel sales 'quickly ran out of steam'
  14. Since you're the one with the fantasies, why you don't tell me what you think I meant?
  15. That’s exactly the opposite of my experience
  16. That's the end of Ukraine then.
  17. Read what I said carefully. The offender is Israeli.
  18. The Israeli's do tend to violate international law...
  19. That’s misinformation, the battery packs are expected to outlast the car, 20+ years. At least one manufacturer gives a lifetime warranty on the battery.
  20. Confucius say... You have election every few years, in China I have election every morning.
  21. It's surprising how much the police in the UK know, my youngest son is involved in the intelligence for that. Most of the drug busts are not accidental, there's usually intelligence involved.
  22. I think the E6 is an Atto Station Wagon Vinny & EOW love you.
  23. That is likely to be an issue. If using a smartphone is mandatory, ie communicating with the manufacturers server, then that part of the functionality is likely to fail. BUT, this is not an EV issue, it applies equally to modern ICE vehicles too. My friend wouldn't be able to do the same things on his ICE Mercedes too.
  24. Excellent video, puts it all in perspective.
