Application: System and method for controlling a high-voltage battery system (Patent ID: US20230396077A1)

The patent filed by The Boeing Co. describes a circuit that includes two switches with diodes, connected to batteries and a load. The first switch is connected to a first battery and the second switch has an opposite polarity to the first switch. Additionally, a third switch is connected to a second battery and a load, providing a configuration that allows for parallel connection of batteries with reduced risk of internal faults.

Furthermore, the patent details a battery assembly consisting of multiple batteries, each connected to a complex circuit with multiple switches and diodes. The assembly enables charging of batteries in series while preventing current flow into specific batteries when switches are off. The configuration also allows for trickle balancing of batteries in parallel, reducing the risk of internal faults and ensuring a single reference voltage for all connected batteries in a series configuration.
