Title: Innovations by Rajesh Nagappala
Introduction
Rajesh Nagappala is an accomplished inventor based in Lake Orion, MI (US). He has made significant contributions to the field of electric powertrain technology, holding 2 patents that showcase his innovative approach to battery systems.
Latest Patents
One of his latest patents is titled "Electrified powertrain with method for determining battery limits based on cell factors." This invention involves a method for adapting the usage level of a battery pack by measuring cell sense data for each respective battery cell. The data includes cell voltage, current, and temperature, which are processed through multiple battery state functions to generate numeric cell degradation values (CDVs). The controller then automatically adapts the usage level of the battery pack based on these values during operation.
Another notable patent is the "Emergency disconnect circuit for high-voltage battery electric system and motor vehicle having the same." This invention features an emergency disconnect circuit designed for high-voltage (HV) battery systems. It includes a pyrotechnic switch that irreversibly opens in response to an electronic triggering signal, disconnecting the HV battery pack from the HV bus. Additionally, a manual switch is integrated to connect a low-voltage (LV) power supply to the pyrotechnic switch, allowing for safe operation in mobile systems.
