anyone now the price for the system from hymotion? poeple telling me that hymotion is providing a plugin kit that only needs 2 hours to build into the prius and privides 50km of range!\ Brem is the name of the plugin kit
You are partially correct. Hymotion had been acquired by A123systems. I attended a talk a couple of weeks ago given by Harvey Wilkinson from A123Systems of Watertown, who brought along a 2007 PHEV Prius. He expects early March 2008 to be the date the BREM (Battery Range Extender Module) will begin to be offered. Estimated price is $9995.00 for a 40-mile pack if I remember correctly. It was amazing to compare the weight of the Lithium Ion battery with a conventional one of the same size. I wish I had a video of the talk, but the local cable in Harvard, Ma. was unable to film it. He explained a lot of things that were way too technical for me to fully grasp, let alone relate to others, but it was quite fascinating. I will definitely be wanting one eventually given the type of driving I do. Check out the site: A123systems.com
I have photos of most of the install (they'd done the computer mod/EV button ahead of time) here if you'd like to see what's involved (go about 4/5ths the way down the page).
I attended a talk and installation. A123 was installing two units in two Prii owned by the local utility company. Unfortunately they kept moving us around for slides and talks and stuff that by the time we got back to the main floor the battery was in and everything was closed up. But the issue of the warranty did come up in the Q&A. A123 said that they'd take over all of the warranty issues. They would cover what Toyota would have covered prior to the install. BTW I checked after the install. They put an EV switch in both cars.
as a upcoming technician and access to high voltage gloves, is it possible to install it yourself? assuming one has all the tools... or heck even offer to install it as a partnership but more details would be nice, i remember in the wiki they said the 5kilowatt pack only had enough EV miles to 15, which made more sense. If a 5 kilowatt pack can provide 40 true ev miles than why does the volt require a 16 kilowatt pack? even though they are using 8 to preserve battery life.
Doc... why bring this up? It isn't true. If you screw up something in the BMS or the original battery, you will likely have trouble getting Toyota to cover it (though even this seems a non-issue from what others have said here). If your brakes suddenly stop working, your seatbelt won't buckle, you radio only plays soft rock, or your antenna fails, there is NO way they can legally deny the warranty claim.
reserve 8kw of the 16 provided? NiMh? its intresting to see that hymotion connects its HV wire's after the HV sensor. look at pictures
nope its lithium a123 cells the exact same used in this hymotion prius alternatively there's competition now Green Car Congress: Valence Technology to Supply Additional 600 Li-Ion Modules to OEMtek for PHEV Conversions 4 kilowatt more for a couple thousand!
Yes. For the Hymotion warranty to cover your Prius the kit has to be installed by one of their trained installers. They guys that did the San Diego install were from San Francisco. I think their shirts said "Joe's Garage". (No kidding.)
yes ok but why only use 50% when a Lithium battery can be used from 10-90%? ( so instead of the 40% there is a 80% usable capacity ( i have read this somewhere )
