Application: Battery monitoring apparatus (Patent ID: US20240198853A1)
The patent filed by Denso Corp describes a battery monitoring apparatus for monitoring unit batteries grouped into battery blocks within an assembled battery. The apparatus includes a battery ECU, voltage monitors mounted on each battery block, and a monitor activation device. The battery ECU wirelessly transmits commands to the voltage monitors, which detect voltage information of the unit batteries and transmit it back to the ECU. The monitor activation device sequentially activates the voltage monitors in a predetermined order, allowing for efficient communication and assignment of IDs to the monitors.
The claims of the patent further detail the configuration and operation of the battery monitoring apparatus. The apparatus is designed to wirelessly communicate with the voltage monitors in a specific order, with the battery ECU assigning IDs to the monitors accordingly. Additionally, the battery ECU can identify each monitor based on the signal sent via wiring. The apparatus also includes connections to an auxiliary battery for power supply and coordination with the vehicle's power switch. Each voltage monitor is equipped with a multiplexer to detect voltage information between the terminals of the unit batteries, enhancing the monitoring capabilities of the apparatus.
