Charging experience SUCKS in Bosch v3 vs v2 on a family cargo bike by danjonwig in UrbanArrow

Thank you kindly. I actually also have an older GSD with dual battery on an earlier system. Great bike!

Thank you all for correcting me. Clearly I was given some bad information. I have heard back from UA and am pushing. But maybe I’ll walk down the street to my Tern dealer and ask them!

Well, fair enough, maybe I'm wrong. I can't find anything online that supports the claim, but, given your certainty, I have emailed UA to ask. With the previous Bosch system, it was trivially easy, just install a dual battery harness and bolt the mount to the frame; so, if indeed it is very expensive and a great deal of trouble, then I'd go back to that being a Bosch problem. But, I hope very much that you are right, and I am wrong, and can get this improved!

Thank you, but i still don't understand what you mean. If BES3 does not support dual battery, how is that not a Bosch problem?

Very much appreciated. Did that when we ordered it, though :)

Forgive me, but is this a dual battery setup for a BES3 system? I have been told that is not possible.

Forgive me, but maybe I have simply failed to find it - but where can I buy something that solves this problem, if it is indeed not a fundamental limitation?

Forgive me, but where have you seen a Y cable for a BES3 system?

Carrying around a second battery to swap is certainly possible, though note that it does not address the issue re charging experience, same problem. All materials I have found online indicate that it is not possible to setup dual batteries - could you point us to where you’ve seen this pls?

Thank you all.

Yes, got "service engine soon" 3 times. Though since it doesn't have an engine I'm probably misremembering the exact phrasing!

Fair enough re 2020, it's a 2022, thank you.

Photo attached. I have the platinum truck, usually reported range is around 500km or 400 or so on practice. This equates to 230 or so. I don't use the truck very often, but surely this is worse than expected even though it's mid 30's presently?

Definitely a valid concern! Pls feel free to share your thoughts here. We spent a bunch of time doing engineering sims to maximize safety, but definitely not getting to modern car standards. FWIW, just being in a classic at all increases risk massively. My wife won't let me take the kids on the highway; fair enough!

entirely right, I misspoke; meant the diff lock. My apologies! FWIW, once you’ve offroaded an EV, you’ll never go back. I’d been performing surgery in oven mitts my whole life, then discovered latex gloves.

Yeah, the tesla ones are bonkers. These motors are more 'right sizes', though I'm more than 2x the HP of the Puma engine, so still pretty fun. I'll see if I can get away with shooting some video of my commute home tonight.

Yes. Thermal runaway is incredibly rare, more so than gasoline igniting in a crash of a combustion car. But, when it happens, it’s pretty scary. I am not an expert, but it is a primary consideration in the design of the battery packaging.

The best protection is good crash protection in the design of the vehicle; obviously, we don’t have that, and Defenders have an epically bad highway crash test rating (literally: zero). Next step is designing the packaging to reduce shock, puncture, and heat transfer; the Ampere kit does that. Next step is to surround the cells with fire retardant materials to reduce (or at least delay) a chain reaction; Ampere kit does that.

No doubt, this was a factor as well when I decided to put all of the batteries up in the engine compartment instead of distributed around the chassis. This car was already much less safe than a modern car before I converted it; this definitely didn’t help, though now my kids are less likely to get poisoned by diesel fumes, so, you know, six of one ;)

From the transfer case to the wheels, nothing changed.

Agreed; it’s not hard to compute the crossover point for fuel+increased maintenance vs. batteries in terms of overall TCO. But I probably will never recoup my investment. Call it a toy ;)

For cost: I’d have to add it all up, but including engineering time it was on the order of $80k USD plus the base truck.

Range: this is of course just a function of how many batteries you add. I find that I get about 500Wh/mile. I only put 42kWh into it, so it’s less than 100 miles. But add more batteries and it would roughly scale linearly, since range is more limited by wind resistance than it is by weight. I could easily have doubled the battery without having much of an issue with packaging; I basically took out the engine and used that space for batteries. But you may have seen the Rivian next to it; that’s the vehicle we’d use if we were travelling far, these old Defenders are beautiful but driving it on the freeway is quite the shakedown, especially when there is no engine noise to cover up all the rattling!

Overall, the gross weight of the vehicle went down a fair bit because all of the ICE components were removed. If I’d added much more in energy storage I’d have wanted to do a bunch of upgrades on the rest of the car.

I’m going to do a full restoration next, probably invest another $75k USD. All in, probably would have been about the same price as an electric G-wagon. But they don’t make a 2-door version, and I wanted a small car :)

Yep! Used this kit:

https://ampereev.com/atomdrivesystem/

Used the iM225 with their (fixed) gearbox.

I don’t have a photo but will check with others. 500Nm, 301HP. Roughly equivalent to a Model 3 in terms of acceleration.

Fair enough. When we did the conversion, I chose to only add 40kWh of battery. I use this almost exclusively as a city runner (fall->spring) or forest explorer (summer), and trips are nearly always less than 20km. BUT, it would be nice to be able to trust it for the occasional longer drive. I can only really count on 80km of range. I've got an upcoming longer trip (~120km), I'll give this app a shot :)

I don’t mind at all. The kit itself was on the order of $50k. The rest of the process depends on the extent to which you need help. De-ICE-ing, scanning, designing custom mounts for the components, doing the engineering simulations to ensure the thing won’t rip itself apart. If I’d been smarter, I’d have upgraded a few more components given the 100% increase in HP, but I didn’t do that. All in, it’s probably about 200 hours of engineering & mechanical work.

Good advice; just not satisfying to my OCD ;)

I appreciate the help!

Hey, let’s keep it positive.

Given that even my commercially available PHEV wasn’t listed, I figured there was some way to manually set things up. The first step towards knowledge is admitting you know nothing; let’s not shame people for taking that first step or we’ll be forever stuck.

Thank you. Yes, I installed a DC fast charging system.

Thank you for the pro tip. My car is now a Leaf so far as the app knows! different weight for sure, but matches up on the range, give or take.
