Which BMS do you have? What sorts of alarms has it given? If there have been no alarms, then it is most likely a loose connection. Try re-torqueing all of your battery connections. You can also measure all of the cells after a long drive - they should all be very close to each other in

I started with the AC24, and now have an 80kw BLDC motor and controller. Lots of pep, handles San Diego freeway traffic with no problem. Now I need to upgrade my batteries to provide the current that the controller likes. :) http://www.evalbum.com/2784 Cheers, Peter On 8/10/14, 6:38

Hi Folks, Take a look at deaths from automobiles in the USA, we are losing over 30,000 people per year. http://en.wikipedia.org/wiki/List_of_motor_vehicle_deaths_in_U.S._by_year Google has self-driving cars that have had 2 accidents - both caused by people. As of August 2012, there have been

Thanks Paul and Martin for the link. As far as I know only Fraunhofer is exploring the vertical pads (aka license plate charging). All others are looking at under the car charging - mainly for EMF/safety reasons. Nice to see such high percentage of efficiency though - 95%! Cheers, Peter On

Took some digging, but using the phrase resonant magnetic induction produce this paper: http://hflab.k.u-tokyo.ac.jp/paper_2010/papers/imura/WEVJ3-2380096.pdf For those that aren't into heavy equations, it shows how you can design coils to absorb resonating magnetic fields over air gaps as

Cable theft is a primary reason for wireless power transfer. Carrying a cable with you just means you make it easier for someone to steal your copper. Heck, even in my relatively safe suburb I have to worry about my power cords disappearing! As for efficiency, I've seen plug-to-battery

I do like Bob's solution for it's simplicity. However, anything mechanical under the car is a non-starter for the OEMs (they claim it is THE most hostile environment in the world). In some ways, this is the equivalent of the J1772 - no power to the lines until you have the power signal active.

You are correct. We are requiring 2-way communication as well as monitoring of the power being transmitted. If some metal does come near/into the field, the transmitter can easily detect this (big change in current) and shut down the transmission. Likewise if the communication fails, power
