Patent number: 11951870Abstract: A battery monitoring apparatus is provided for monitoring unit batteries of an assembled battery which are grouped into battery blocks. The battery monitoring apparatus includes a battery ECU, voltage monitors each being mounted to a corresponding one of the battery blocks, and a monitor activation device. The battery ECU is configured to wirelessly transmit commands to the voltage monitors. The voltage monitors are configured to detect voltage information of the unit batteries and wirelessly transmit the detected voltage information to the battery ECU. The monitor activation device is configured to sequentially activate the voltage monitors with time lags in a predetermined order recognized by the battery ECU.Type: GrantFiled: August 5, 2021Date of Patent: April 9, 2024Assignee: DENSO CORPORATIONInventor: Fumihiko Hori

Patent number: 11830989Abstract: In a battery system including an assembled battery having a plurality of battery cells connected in series, each of a plurality of monitoring units includes a voltage classification unit configured to classify a terminal voltage between each pair of input terminals in the monitoring unit as a cell voltage or as a zero voltage that is a terminal voltage of substantially zero. The input terminals in each of all or all but one of the monitoring units include at least one specific terminal pair for acquiring the zero voltage at a different position and/or include a different number of specific terminal pairs for acquiring the zero voltage. Each of the plurality of monitoring units further includes an identifier generation unit configured to generate an identifier based on at least one of the position of the at least one specific terminal pair and the number of specific terminal pairs.Type: GrantFiled: July 13, 2022Date of Patent: November 28, 2023Assignee: DENSO CORPORATIONInventors: Naoto Yamashita, Masakazu Kouda, Fumihiko Hori, Shunichi Kubo
