BATTERY MANAGEMENT DEVICE AND MOBILE ROBOT COMPRISING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240222991 titled 'BATTERY MANAGEMENT DEVICE AND MOBILE ROBOT COMPRISING SAME

Simplified Explanation

The patent application describes a system that manages multiple batteries to generate a stable power supply voltage. It includes a controller that selects a main battery and auxiliary batteries based on their output voltages, periodically connecting and disconnecting them for monitoring.

• 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 detect output voltages from batteries
• Detection connection switching unit connects or disconnects batteries to/from voltage detection units
• Battery controller controls switching units based on voltage information
• Main battery and auxiliary batteries are selected and monitored based on their output voltages

Potential Applications

This technology can be applied in various devices that require stable power supply from multiple batteries, such as portable electronics, medical devices, and industrial equipment.

Problems Solved

This technology addresses the challenge of managing multiple batteries efficiently to ensure a stable power supply without overloading or draining any individual battery.

Benefits

- Improved reliability of power supply - Efficient management of multiple batteries - Enhanced performance of devices requiring stable power supply

Questions about Battery Management System

How does the system select the main and auxiliary batteries?

The system selects the main battery based on the output voltages of all batteries and designates the remaining batteries as auxiliary batteries.

What are the potential risks of not properly managing multiple batteries in a system?

Improper management of multiple batteries can lead to uneven power distribution, premature battery failure, and potential safety hazards.

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.
