We presented on the Orion BMS at last month's meeting and indicated there would be a $250 discount coupon valid for the month of April 2011 which is below. We also have a giveaway contest running until May 31st for the 2 most creative solutions to using the Orion BMS to reduce dependance on fossil fuels. The contest instructions can be found at this URL:
http://www.orionbms.com/orionbms-giveaway-contest/The Orion BMS is a robust and cost effective centralized BMS designed to completely automate the process of maintaining batteries. There are no cell boards to install greatly simplifying the installation process. The BMS is highly programmable and can be setup to work in just about any application and with just about any li-ion and even some NiMH packs. The centralized design allows for significant improvements in electrical noise immunity and can survive with as many as 60% of cells having failed. It constantly monitors the battery pack for failed cells and can detect cells with a higher internal resistance or lower capacity and automatically set error codes if a faulty cell is detected. Error codes can be pulled with an OBD-II scan tool or the provided PC software and identify not only which cell has failed in the pack, but also the circumstances under which it failed and the condition of the cell at the time of the failure. The BMS also constantly calculates and provides maximum current limits for charge and discharge for a motor controller which preemptively protects the batteries from over / under voltage even at low states of charge and at low temperatures where other BMS systems simply trigger an alarm after damage has already been done from drawing the voltage down too low (which provides a limp home mode.) There are many other features that can be found here:
