Abstract
The present disclosure relates to a battery pack and a wireless communication apparatus, and a wireless communication method thereof, and a technical problem to be solved is to propose a mechanism that enables a master battery management system (BMS) and a plurality of slave BMSs to perform radio frequency (RF) communication through a repeater based on an active phased array antenna system. To this end, the present disclosure is directed to providing a configuration that enables the collection of status of a battery pack and the transmission of corresponding control signals through a repeater based on an active phased array antenna system that performs RF communication between a plurality of slave BMSs and a master BMS.
Claims20
A battery pack comprising:
- a pack case;
- a plurality of battery modules mounted inside the pack case;
- a plurality of slave battery management systems (BMSs) that are mounted on each battery module and collect battery status information of each battery module;
- and
- a master BMS configured to receive the battery status information from each of the plurality of slave BMSs through radio frequency (RF) communication and integrate and manage the plurality of slave BMSs,
- wherein RF communication is performed between the plurality of slave BMSs and the master BMS through a repeater based on an active phased array antenna system.
A wireless communication apparatus comprising:
- a plurality of battery modules mounted inside a pack case;
- a plurality of slave battery management systems (BMSs) that are mounted on each battery module and collect battery status information of each battery module;
- a master BMS configured to receive the battery status information from each of the plurality of slave BMSs through radio frequency (RF) communication and integrate and manage the plurality of slave BMSs;
- and
- a repeater based on an active phased array antenna system that is configured to perform the RF communication between the plurality of slave BMSs and the master BMS.
A wireless communication method of a battery pack, comprising:
- measuring, by each of a plurality of slave battery management systems (BMSs), battery status information on each of battery modules and converting the measured battery status information into a radio frequency (RF) signal;
- transmitting, by each slave BMS, the RF signal to a master BMS through a repeater based on an active phased array antenna system;
- receiving, by the master BMS, the RF signal through the repeater;
- analyzing, by the master BMS, the battery status information corresponding to the RF signal;
- and
- transmitting, by the master BMS, a control signal according to a result of the analyzing of the battery status information to each of the plurality of slave BMSs through the repeater.
