Patent for Sale:Smart-Battery Monitoring over Power Circuit
A monitoring device is embedded within each cell, measuring its operating conditions from within, and containing its life-time use history and serial number for long-term diagnosis. The monitoring device periodically transits modulated cell operating conditions over the direct-current power bus by coupling the modulated data onto the power bus by means of a Rogowsky coil mounted on one of the power terminals within the cell enclosure.
A collection system is decoupling the signals from all cells in a battery system by means of a similar Rogowsky coil, demodulates and discriminates the signals, and transmit the data to the battery system controller.
The cell operating condition data is used to optimize the charging process, and regulate the energy consumption for prolonged cell life and optimal power storage effeciency.
Primary Application of the Technology
When a battery system is expensive to replace, it is cost-effective to employ advanced cell monitoring methods to optimize charging and discharging profiles and initiate preventive maintenance, all to achieve the best possible energy exchange efficiency, and extend the useful life of the battery system.
Other present systems that include a monitoring device locally at each cell, require a separate communications bus which must employ galvanic isolation circuity to mitigate the high voltage difference between all cells in a system. This communications bus is also susceptible to a verity of maintenance-related difficulties.
The patent proposes to use the direct-current power bus as a communications medium, and discloses a method of communications specifically aimed at the direct-current power bus, a communications method that is robust, scalable and does not emit any radio frequency interference.
