Patent number: 11656294Abstract: A method for providing battery diagnostics includes: measuring a first voltage across a first battery cell of a rechargeable battery via a first measurement path of a network using a first measurement circuit, measuring the first voltage including taking at least one first voltage sample during a first time period using the first measurement circuit; measuring a second voltage across the first battery cell via a second measurement path of the network using a second measurement circuit, measuring the second voltage including taking at least one second voltage sample during the first time period using the second measurement circuit, where the second measurement path of the network is different from the first measurement path of the network; comparing the measured first voltage with the measured second voltage; and generating a diagnostic output signal based on the comparison.Type: GrantFiled: January 8, 2021Date of Patent: May 23, 2023Assignee: Infineon Technologies AGInventors: Felix Weidner, Jesus Ruiz Sevillano, Maximilian Hofer

Patent number: 11233406Abstract: A battery management system is described that includes a controller configured to control electrical charging and discharging of a plurality of blocks of a battery. The battery management system also includes an inter-block communication network including a master node and a plurality of slave nodes arranged in a ring-type daisy-chain configuration with the master node. The master node is coupled to the controller and configured to initiate all command messages sent through the inter-block communication network and terminate all reply messages sent through the inter-block communication network. The plurality of slave nodes is bounded by an initial node coupled to the master node and a last node coupled to the master node.Type: GrantFiled: November 14, 2019Date of Patent: January 25, 2022Assignee: Infineon Technologies AGInventors: Clemens Kain, Guenter Hofer, Jesus Ruiz Sevillano

Patent number: 10436852Abstract: In one example, a circuit includes a first integrated circuit and a second integrated circuit. The first integrated circuit is configured to detect a first battery voltage that is associated with a first battery cell and output a representation of the first battery voltage. The first integrated circuit is further configured to detect a second battery voltage that is associated with a second battery cell that is connected in series with the first battery cell and output a status signal indicating whether the second battery voltage satisfies a first threshold. The second integrated circuit is configured to detect the first battery voltage and output a status signal indicating whether the first battery voltage satisfies a second threshold. The second integrated circuit is further configured detect the second battery voltage and output a representation of the second battery voltage.Type: GrantFiled: August 4, 2016Date of Patent: October 8, 2019Assignee: Infineon Technologies AGInventors: Jesus Ruiz Sevillano, Guenter Hofer
