The next step is putting in the battery management system which will monitor the status of all of the batteries.  I have been working with Charlie Malone who has designed a really nice system.  I am working on the computer display system for his electronics.  The computer display system will also monitor what is coming out of the motor controler, which in my case is the Zilla.  Below are are some preview shots of what the display is going to look like.  It will run on either an iPad or Samsung Tab.

Lithium Ion Battery Racks

Restoring and Building | Posted by admin October 23rd, 2011

The batteries arrived from Calb Battery nicely packed in wood crates.

My first step was to check out how they would all fit in the battery compartment area. They are very different in size from the lead acid batteries that were removed. This meant I was going to need to make new battery racks.

One of the issues with lithium batteries is the heat. They don’t like the heat and if they get too hot it will decrease their life. This is especially true in Florida. To solve this problem, I am installing a ventilation system in the back to remove some of the heat. The system is going to be powered by photovoltaic solar cells mounted over the battery pack. The small solar array will also help shade the batteries from the sun.
