Renault had 12 patents in artificial intelligence during Q4 2023. Renault SA’s patent involves a method for managing a network of storage batteries in electric vehicles, where multiple batteries are connected in parallel with relays for isolation. The method includes acquiring the state of charge for each battery, determining control setpoints for the relays based on the acquired data, and controlling the relays accordingly. The computer also acquires a parameter related to the battery wear level to determine the control setpoints.

Application: Method for managing a network of storage batteries and power supply unit of an engine (Patent ID: US20230373348A1)
The patent filed by Renault SA describes a method for managing a network of storage batteries in an electrically propelled motor vehicle. The method involves acquiring the state of charge for each storage battery, determining a control setpoint for each relay based on the acquired states of charge, and controlling the relays accordingly. The computer acquires a value of a first parameter related to the level of wear of each storage battery, and the control setpoints are determined based on this parameter.
Additionally, the method can involve acquiring a value of at least a second parameter such as voltage, temperature, or vehicle configuration, and using this information to determine the control setpoints. The control setpoints can vary based on the vehicle's acceleration or braking phase, ensuring efficient battery usage. Furthermore, after using the vehicle, the method includes determining an instruction to charge the storage battery with the lowest state of charge in an external power network, provided that the battery has lower wear than the others. The patent also includes claims related to a power supply unit for the motor vehicle engine, incorporating the described method for battery management.
