Solution Overview

Problem

Existing electric devices, particularly those with battery-powered systems, face challenges in dynamically regulating power to prevent damage from excessive power output due to faults or shorts, as traditional Battery Management Systems (BMS) rely on predetermined limits that may not account for real-time operating conditions, leading to potential damage to batteries and components.

Innovation Solution

A method and apparatus for an electric device that dynamically sets and adjusts power thresholds based on real-time operating power levels, using a power regulator that compares output power levels with set thresholds and reduces them if exceeded, incorporating a trained machine learning model to predict power usage and adjust thresholds according to operating modes and reference demands, and disconnects faulty components to prevent damage.

1Reliability

If predetermined power limits are used in traditional BMS, then device complexity is reduced, but reliability deteriorates due to inability to account for real-time operating conditions

Engineering Contradiction:

Solution Approach 1:

The patent implements dynamic power threshold adjustment by continuously monitoring real-time operating conditions (temperature, state of charge, current draw) and adjusting power thresholds accordingly. The BMS transitions from static predetermined limits to dynamic adaptive thresholds that respond to changing operating conditions, thereby improving reliability without requiring overly complex system architecture.

Inventive Principle:

Solution Approach 2:

The system incorporates feedback mechanisms by continuously monitoring operating parameters (temperature, voltage, current) and using this information to adjust power thresholds in real-time. This closed-loop feedback approach enables the BMS to adapt to real-time conditions, improving protection reliability while maintaining manageable system complexity through intelligent control algorithms.

Inventive Principle:

2Reliability

If dynamic power threshold adjustment is implemented, then protection effectiveness is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The patent changes the parameter of power thresholds from fixed predetermined values to dynamic values that adjust based on operating conditions. By monitoring parameters such as temperature, state of charge, and current draw, the system dynamically modifies power thresholds to match real-time requirements, enhancing protection effectiveness while using computationally efficient algorithms to manage complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The BMS performs self-adjustment of power thresholds based on its own monitoring of operating conditions. The system serves itself by automatically detecting when protection is needed and adjusting thresholds accordingly, eliminating the need for external intervention or overly complex control systems while maintaining high protection effectiveness.

Inventive Principle:

Solution Approach 1:

The system implements continuous monitoring of operating power levels and operating conditions without interruption. By maintaining constant surveillance of temperature, state of charge, and current draw, the BMS ensures power delivery safety through uninterrupted monitoring while using efficient processing to minimize response delays, thereby reducing loss of time in power response.
