Odyne Awarded Patent for Battery Energy Management and Monitoring System
3 October 2008
Odyne Corporation, a developer of medium- and heavy-duty plug-in hybrid electric vehicle propulsion systems, has been awarded a US Patent (application number 11-315,927) for its Battery Energy Management and Monitoring System. Odyne has now been awarded three patents in the area of Battery Energy and Thermal Management.
The use of the technology embodied in this patent will improve the functionality and extend the operating life of battery modules used in mobile applications. Electric and Hybrid Electric Vehicles require the series connection of many battery modules to get the voltage up to ranges as high as 400VDC to 800VDC. When this is done, it is necessary to monitor each of the modules to make sure that they do not become electrically imbalanced which leads to poor performance and life expectancy. The Battery Management System monitors and provides an equalization function to ensure all the batteries are acting together which maximizes the capacity of the entire string. Odyne’s Battery Management System can be used on any battery chemistry.
—Joe Ambrosio, founder and CTO of Odyne
Approved for patent is a battery monitoring and equalization system which monitors the temperature and voltage of each battery module. In addition, the system allows for the equalization of each battery module through an intelligent network. The key feature of the system is that it stores information on battery operation when the vehicle is being operated and during charging. This information is used to determine when to equalize deficient modules, calculate accurate state of charge, maintain safe operating parameters and predict battery failure.
The system is also an important diagnostic tool for service personal when inspecting battery packs. The system is comprised of a main controller and individual sensor nodes which are affixed to each module. The nodes are connected via a data and power network which is easily integrated into a battery pack design.

>>A single piston engine optimised to directly drive a large flywheel at high speeds is the most compact, high energy, very-high-power cheap energy storage device. Electricity or fluids can drive the wheels. ..HG..<<<
I prefer this concept:

a brilliant mechanical engineering concept.. note how they use the accumulator as the main structural member of the car.. the simplicity of this hybrid is staggering. Should be low cost as well.. and fewer moving parts compared to a flywheel storage device.

How could they patent such a basic part of electric vehicles?.. pretty common sense stuff I would think..

Listed below are links to weblogs that reference Odyne Awarded Patent for Battery Energy Management and Monitoring System:
AC propulsion did the same thing for its TZERO and prototypes when using lead acid batteries.
ZEBRA battery cells do not need any such monitoring of the cells and have been used in packages exceeding 600 volts. Price is the only real impediment to the use of ZEBRA batteries.
