Amazing videos! Quick one - is it normal to feel vibrations through the steering wheel when the compressor is running? Noticeable when stationary and mostly during winter or high temps in summer? It's not violent or anything but very noticeable. Hopefully it's normal 🤞
@garycevrepairs37 минут бұрын
Hi yes the compressor can vibrate quite a bit which you feel through the steering wheel. The ac compressor is a bit undersized for the system, it’s a heat pump and dual ac system with the battery cooling loop. If it’s making a metallic noise/grinding then that could be a sign of low gas but a fair bit of vibration is normal. If concerned get the gas level checked. Cheers

Really interesting stuff Gary. I've been wondering if one of these or a Zoe might do for my father to run around locally. I can't help thinking that if you have a Zoe, Leaf, iMiev or similar, dropping a new battery in with the latest energy density, would give them a massive boost in usefulness. I know this would require software and some hardware changes and what people will want to spend will relate to the value of the car, but I for one would be very interested in keeping an older EV long term, especially if it has a decent range and faster charging capability. The cost of new batteries is still dropping rapidly and I suspect that some of the boffins that already faff about with EVs, will find they can use a CCS charge port and inverter off a written off X or Y. I had a 2014 Kangoo ZE max and that would have been so much better with better range and CCS charging. There was plenty of space underneath for a second battery and I was not carrying heavy loads, so overall weight was not an issue. There's got to be a market for this, and the tech gets cheaper and knowledge improves. In the meantime, its great to see you keeping these cars on the road, without breaking the bank.
@garycevrepairs12 сағат бұрын
Hi yes there are people who do battery upgrades for the i-miev although it is rather expensive for an old car and may not have been through the same rigorous safety testing as a production vehicle. That being said there needs to be more options to extend the life of older vehicles with worn batteries. Cheers.

Manufacturers 'could' design-out the 12v battery by using a voltage downconverter from the HV battery. This would need to be 'always-on' and independent of the HV contactor. This is a potentially risky solution, making it difficult to protect the HV battery as it discharges when the car is idle. It is hard to see the replacement of the 12/24/48v battery in the near term.

They mostly aren't. Most of what needs fixing is simple brakes, suspension and steering. The power train is very simple too. The only thing that makes anything expensive is the required training to handle the high voltage side of the system. At the moment there aren't many who are trained, so those repairs are more expensive than they need to be. There hasn't been enough time for 3rd party suppliers to produce even cheaper spare parts yet, but that will come. It's not about complexity. Early adopters always pay more for their purchases.

You are amazing man! This is super investigative work on Zoes that we don't really see elsewhere. So happy to see these videos always👍 Okay but let's think about the bearings, This rust on the surface of the bearing looks so much like pitting from electric current damage🤔Now it looks very likely that electric currents are contributing to the bearing failures on these motors. It is common on variable drive AC motors. If that is the case, when you open the bearings and cut them open, you may see grease is "burned" dark and there can be fluting patterns on raceways, or matted surfaces. When is gets worse, bearing balls also can get damaged and bigger pieces will get off, these damages will start generating heat. It is so weird how little amount of hours are on this bearings, and they fail already. I started thinking if it is possible that currents are induced in the motor shaft during charging too because Zoe motor is a charger inductor...but this would be crazy.
@garycevrepairsКүн бұрын
Hi thank you! Glad you are enjoying the videos, I’ve been amazed by the response I’ve had. From chatting to a few people it has been mentioned that the cause could be discharge from the rotor to the case. The Nissan Leaf has a magnetised rotor and interestingly has a single carbon brush on the rotor to make sure it is at the same potential as the case so that there is no discharge through the bearings. The Zoe motor of course only has the two brushes required for rotor excitation. One of the reasons I favour fitting metal shielded bearings is because this gives another path for discharge rather than through the bearings and they are still reasonably well sealed from any dust or moisture. Need to do more analysis on old failed bearings (I’ve got plenty 😆) but of course the main push is to get the cars fixed tho I like learning how stuff works and why it fails so I will do that investigation one day! Cheers.

@@garycevrepairsI think the quality of the motor housing might be an issue. It seems to be just diecast aluminium rather than a more corrosion resistant alloy. I'm wondering if the corrosion between the mating surfaces is causing a slight angular deviation between the spindle and the housing which contains the bearing receiver - it wouldn't take much, given the speed and torque the motor develops to destroy the bearing. I think the electrical arcing theory is also a good one.
@zev-t6y4 сағат бұрын
As an irony the "permanent" magnet "brushless" motors aren't either. So Zoe may be the only car carrying its own real charger. But Renault patented the Cameleon and the rest of the world went DC charging (ie external) There's only so much a smack of grease can do for lifetime reliability; another issue is two separate shafts, which leads to misalignment and splines issues. Solvable with some modifications

Given that you're in the UK it doesn't seem like the ideal solution. In Australia we'd have simply built a shed out of galvanised steel. You can buy them in kit form - say a 3.75m x 7.5m shed would cost you around $AU2800 or about £1400. Maybe allow £500 for a concrete floor if you want to keep the water out completely. I'm sure there's reasons to go for such a flimsy solution - maybe council approval's difficult, but it looks like you're fairly rural. Maybe sheds are a lot more expensive in the UK?

That looks quite labour intensive! Obviously not designed for high mileages then? I'm guessing there's going to be a lot of these getting scrapped soon, seems a bit controversial given that they are supposed to be better environmentally. Re bearings. It seems fairly obvious they're going to fail in such an application. These are sealed for life bearings so they're running in the same lubrication continually. In many industrial motors there used to be a reservoir and an oilway into the bearing so that fresh lubrication could be added occasionally. High speed sealed bearings aren't designed to last forever, especially relatively lightweight ones such as those.
@garycevrepairs2 күн бұрын
Hi yes very labour intensive unfortunately as the whole front end has to come off to access the motor. I’m not sure what’s causing the bearings to fail, they should last a long longer as the car is used for a couple of hours max as you’d need to stop to recharge after that so it shouldn’t be that hard on the bearings ! Cheers.
@Altair8852 күн бұрын
@garycevrepairs Yeah, you'd expect a motor to give you a bit longer than that. But then there are a lot of factors involved, speed probably being one of the biggest, and of course vibration. Running at those speeds the rotor only needs a very slightly imbalance to induce a hammering action on the bearing. I presume the rotor is quite heavy in these? I've worked on diesel gensets and have rebuild a few alternators over the years so I've got an idea what sort of weight it's likely to be. Those sets only ran at 1500rpm, even so the bearings were substantially heavier comparatively for an alternator of a similar size, and even they would wear out after a few thousand hours! Even if the rotor was perfectly balanced, which is unlikely as it's aircooled and likely to be contaminated with debris over time anyway, there's always the electromagnetic effects to consider. I know these motors are three phase which considerably better than single phase, but even so they can suffer from having different field strengths creating an imbalance. At thousands of rpms that's all going to have an effect on bearing life over time. Is it just the motors in Renault EVs that start to show signs of wear at such early mileages, or is this a general problem in most EVs? I notice there seems to quite a few breakers now offering EV traction mothers for sale, so I was wondering if there's a big demand for them now? Cheers.

For battery-side issues, we need modular standards so bad battery packs can easily be repaired or upgraded one module at a time. If such standards existed, we'd have 5-10kWh modules with prices that track closer to cell prices. Pop the battery armor plate/cover off from the bottom, remove the problematic module(s), pop the new one(s) in, put the cover back on, done, $1500-2000 per module, 2h of time to remove the cover and put it back on including removing sealant residue and putting new sealant on, ~5min per module for the swap itself. The other major obstacle to EV repair is how access to most modules is locked behind expensive scan tool and OEM server subscriptions. Having the parts does you no good without access to the necessary programming tools, firmware updates and whatever other software locks OEMs put in their hardware to prevent DIY/independent service.
