[EVDL] Lithium Ion buddy pairing? (Was electriccarpartscompany.com?)

2018-07-31 Thread Tom Hudson via EV
It turns out there was some sort of website form problem and I was able to talk to Matt at 
the Electric Car Parts Company today -- working on the order now.


So here's a troubling issue with my setup:

I'm planning to set up the batteries in my Solectria E-10 pickup as a single string of 
buddy pairs of CALB CA100 lithium-ions. I'm working with a nominal 144V setup in this 
truck and figure the buddy pairs are the best way to limit the current each battery module 
sees. I have 56 of them from my Solectria Force now, and my plan is to use them and pick 
up additional batteries to bring the total to 96 modules (48 buddy pairs), and set the 
whole thing up with an Orion BMS to wrangle the batteries and keep them in good shape.


I wanted to be sure that I had 56 good batteries from the Force so I opened up the battery 
boxes today.  All the modules look great.  I started taking voltage readings and all the 
batteries were between 3.31 and 3.34 volts -- except for two of them.


Those two were ZERO VOLTS, and show ZERO OHMS resistance.

Is this a common failure mode of lithium-ions (or the CALB modules)?  I'm thinking that 
I'd better set up some kind of fusing between the buddy pairs because if one of the pair 
fails in this way, it's going to present a dead short to its buddy -- and nothing good is 
going to come of that.


Comments?  Suggestions?  I'm wondering what size & type fuse I should use on the buddy 
pairs to deal with this scenario and if such a fuse would be enough. I think the maximum 
current draw on the truck will be around 480A (two Brusa AMC320 motor controllers @ max 
240A each).

The One electric city car [
https://newatlas.com/uniti-one-city-car/52543/
] from team Uniti has spent much of its testing time indoors so far, but the
company recently decided to take advantage of the glorious (northern) summer
sunshine and take the electric micro car for a spin around southern Sweden.

Where Renault's similarly-sized Twizy quadricycle has a maximum range of 100
km, the One is promised to roll for 300 km (186 mi) before needing a
recharge of its relatively small 22 kWh battery pack. That's almost in
Nissan Leaf territory and claimed possible thanks to the vehicle's
lightweight and energy-efficient design. A removable auxiliary battery unit
can be charged up at home or in the office for an additional 30 km of range.

The two-seater is expected to be just 2.91 m (9.5 ft) long, 1.275 m (4.1 ft)
wide and 1.428 m (4.6 ft) high and have a dry weight of 450 kg (990 lb). It
will go from standstill to 80 km/h in 3.5 seconds, on its way to a top speed
of 130 km/h (80 mph), which again trumps the Twizy.

The passenger is seated behind the driver, who faces a tablet-like display
in the middle of twin joystick handlebar steering controls and enjoys good
visibility thanks to a relatively large windshield. A full suite of safety
sensors for such things as collision avoidance will also feature.

The successfully crowdfunded [
https://newatlas.com/uniti-ev-crowdfunded/45830/
] Uniti One is expected to go on sale next year for a starting price of
€14,900 (about US$17,300). The video below shows the vehicle being driven
around the Swedish countryside.

We've hit 1000km in our long-term EV. Time to take a closer look.

We've hit 1000km in our long-term EV. Time to take a closer look.

BMW i3s LONG TERM TEST
Base price: $85,900 (our car: $92,640).
Mileage so far: 1000km.

Powertrain and performance: BMW eDrive electric motor with eight Lithium-ion
modules, 33kWh capacity, 135kW/270Nm, single-speed automatic, RWD. Average
power consumption on test 17.5kWh/100km (average range 189km), official
Combined power consumption 14.3kWh/100km (Combined range 230km).

What have we done lately? Had toasty-warm mornings, nearly run out of juice. 
Problems so far: None with the car, careless driver that nearly ran out of
juice.

How's your winter been? Mine's been quite pleasant actually, thanks mostly
to our long-term BMW i3s.

I have a relatively early commute to work, leaving at 6.30am. The car lives
in a carport but is technically outside, so the temperature can be a bit,
well, refreshing on a winter morning.

You can stay very warm and still be very green in the i3s. But you have to
spend another $1100.

Not with the i3s though, which is always beautifully warm inside before I
get into it. That's due to a couple of techy tricks.

One's a smartphone app called BMW Connected that gives you real-time access
to the car via an embedded SIM card. You can do all kinds of stuff but
there's one function called Climatise Now, which allows you to heat the
car's interior remotely in preparation for your trip. You can either do it
on demand or set it for a particular time.

BMW Connected app happy to suggest new cars you might added to the fleet.
Dream on.

This is not something unique to the i3s or even to BMW, but our car takes it
to the next level. It's fitted with an $1100 heat pump that heats the
ambient air much more quickly and efficiently, which means you get
toasty-temp straight away without taking too much charge away from your
precious battery and eating into driving range.

Extravagant? Yes. Necessary in New Zealand, especially the relatively mild
climes of Auckland? Well no.

But as previously discussed, I do object to EV discussion being solely about
running-costs and other boring stuff. The i3s is not a boring car. If you're
spending $90k on a premium machine, why not have a heat pump and whatever
else you want and can afford? Love it.

Come in, the temperature's fine... any time you want.

The BMW Connect app is pretty smart generally. Smart enough to recognise
that I'd paired my phone to the BMW i8 [pih] roadster I had on test recently
and add that vehicle to the Connected menu in case it was a permanent part
of the family fleet. I wish.

And no, you don't just get control of a car that easily; to activate it you
have to input information that you only have access to if you're actually
driving the vehicle.

We've racked up 1000km of mostly city commuting in the i3s, although a lot
of that is motorway work.

Here's the screen you don't want to see: desperately low on charge.

It's still weird thinking in terms of power consumption rather than litres
per 100km, but on test so far the i3s has averaged 17.5kWh per 100km through
some very enthusiastic driving, which translates to a theoretical range of
189km.

In general I've not found it a chore charging up and at no time have I
thought the range-extender version with the petrol generator would be
desirable, but I do concede that you probably have to be a car person to run
an EV like this because you have to be focused on the vehicle.

By the time you're down to 50km range for example, you have to think pretty
seriously about when you can plug in next.

Hi,

Does anyone here have any experience using BMS developed by a battery
manufacturer such as those provided by A123, LG Chem etc. Davide Andrea the
founder of Elithion in his book on BMS design has mentioned that these guys
try to rip you off. Anyone here has any opinion or perspective to offer ?
