BATTERY MANAGEMENT DEVICE AND MOBILE ROBOT COMPRISING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18293433 titled 'BATTERY MANAGEMENT DEVICE AND MOBILE ROBOT COMPRISING SAME
The abstract describes a patent application for a power supply unit that generates operating power supply voltage from multiple batteries, with a switching unit for connecting or disconnecting the power supply unit to each battery. There are voltage detection units to monitor output voltages from the batteries, and a controller that selects a main battery and auxiliary batteries based on their output voltages.
- Power supply unit generates operating power supply voltage from multiple batteries
- Power connection switching unit connects or disconnects power supply unit to/from each battery
- Voltage detection units monitor output voltages from batteries
- Detection connection switching unit connects or disconnects batteries to/from voltage detection units
- Battery controller selects main battery and auxiliary batteries based on output voltages
- Auxiliary batteries are periodically disconnected and reconnected for monitoring
Potential Applications: - Portable electronic devices - Electric vehicles - Renewable energy systems

Benefits: - Prolonged battery life - Enhanced power efficiency
Commercial Applications: Title: Advanced Battery Management System for Improved Power Efficiency This technology can be used in various industries such as consumer electronics, automotive, and renewable energy sectors to optimize power usage and extend battery life.
Questions about the technology: 1. How does the battery controller determine which battery to select as the main battery? 2. What are the advantages of periodically disconnecting and reconnecting the auxiliary batteries for monitoring purposes?
Original Abstract Submitted
The present disclosure includes: a power supply unit which generates an operating power supply voltage from a plurality of batteries; a power connection switching unit which performs connection or disconnection of the power supply unit to or from each of the batteries; a plurality of voltage detection units which detect output voltages output from the respective batteries; a detection connection switching unit which performs connection or disconnection of each of the batteries to or from each of the voltage detection units; and a battery controller which controls the power connection switching unit and the detection connection switching unit based on information input from the voltage detection units, wherein the battery controller selects, as a main battery, one of the plurality of batteries based on the output voltages, selects remaining batteries as an auxiliary battery, and connects the auxiliary battery to the voltage detection units for a first time period, and periodically repeats disconnection for a second time period, wherein the first time period is shorter than the second time period.
