[EVDL] Lithium Ion buddy pairing? (Was electriccarpartscompany.com?)
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). -Tom ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

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).

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. Extra track and larger wheel
