Latest Patents

One of his latest patents is for a "Battery module with active cell balancing using energy storage element and two tiers of switches." This innovative battery system includes a battery module, an active cell balancing circuit, and a battery controller. Each cell is designed with diametrically-opposed positive and negative cell tabs. The circuit features voltage sensors and, at each end of the battery module, first and second tiers of switches along with an energy storage element. The controller receives measured voltages from the sensors, which indicate the electric potential between adjacent battery cells. Based on these measurements, the controller commands the first tier to selectively connect or disconnect designated pairs of cells to the corresponding second tier. Additionally, the second tier is commanded to connect or disconnect the designated cells to a corresponding energy storage element, effectively balancing the state of charge among the cells.

Another significant patent is for a "High-voltage system with low-voltage control architecture and method." This high-voltage electrical system comprises a high-voltage electrical bus, a low-voltage controller performing battery management system (BMS) functions, and a rechargeable energy storage system (RESS) connected to the HV electrical bus. The RESS includes contactors connected to the voltage rails, a battery pack, and a current sensor that outputs a voltage signal indicative of pack current. The system also features cell monitoring units (CMUs) that measure corresponding cell voltages and voltage isolation hardware between the CMUs and the LV controller. The LV controller performs designated BMS functions, including monitoring pack current and controlling the open/closed state of the contactors.
