Solution Overview

Problem

Battery systems often experience power leakage when not in use, leading to a limited shelf life and requiring an external power source to transition from a low power mode to a functional mode, which is inefficient.

Innovation Solution

A battery system with a set of coupling means, energy means, discharge means, and status means that allows the battery to internally manage transitions between low power and functional modes, using its own energy to switch between these states, thereby reducing power consumption and eliminating the need for an external power source.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the battery system uses an external power source to transition from low power mode to functional mode, then the transition can be achieved, but the system complexity and dependency on external sources increase

Engineering Contradiction:
Improvetransition capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The battery system uses its own stored energy to power the transition from low power mode to functional mode, eliminating the need for external power sources. The status means detects energy availability and controls the discharge means to activate coupling means using internally stored energy, making the system self-sufficient and reducing external dependencies.

Inventive Principle:
Principle #25Self-service

2Productivity

If the battery system continuously monitors and manages mode transitions, then operational efficiency improves, but power consumption increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The status means periodically monitors energy levels and transition requirements, activating the discharge means only when necessary to effect mode transitions. This periodic monitoring and controlled activation reduces continuous power consumption while maintaining operational efficiency, as the system only expends energy for status management when transitions are needed.

Inventive Principle:
Principle #19Periodic action

3Adaptability or versatility

If the battery system uses internal energy for mode transitions, then dependency on external power is reduced, but the available energy for external loads decreases

Engineering Contradiction:
Improveindependence from external powerVSAvoidavailable energy
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system dynamically adjusts the parameters of energy distribution by monitoring the state of the battery cell and external circuit requirements. The status means evaluates energy availability and controls the discharge means to allocate appropriate energy amounts for transitions versus external loads, optimizing the balance between maintaining independence and preserving energy for primary functions.

Inventive Principle:
Principle #35Parameter changes

AI summary

Systems and methods for controlling transitions between a low power mode of operation and a functional mode of operation of a battery system use power provided by the battery cell in the battery system to cause the transitions. The battery system includes a status circuit, a charge/discharge circuit, a set of battery ports, and/or other components. During the low power mode of operation, at least the charge/discharge circuit is rendered inoperative, thus saving power.
