Battery Protection Polling Circuit With Priority-Based Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery protection technologies waste power consumption and resources due to constant polling intervals, which become more pronounced with an increase in detection items, rendering them inefficient and wasteful.
Innovation Solution
A battery protection chip and polling detection circuit that prioritize detection items, allocating time and resources effectively by using a polling signal generator to determine the next item to be detected based on priorities, ensuring timely and efficient polling through a combination of polling clock signals and selection signals, thereby optimizing the detection of key performance parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If constant polling interval is used to monitor all detection items, then polling timeliness is ensured, but power consumption and resource waste increase significantly
Solution Approach 1:
The patent applies dynamics by making the polling interval adaptive rather than fixed. The control unit dynamically adjusts the polling interval for each detection item based on its priority level and historical data, allowing high-priority items to be polled more frequently while low-priority items are polled less often, thus resolving the contradiction between polling timeliness and power consumption
Solution Approach 2:
The patent implements local quality by assigning different polling frequencies to different detection items based on their specific needs. Each detection item receives a customized polling strategy tailored to its importance and characteristics, rather than applying a uniform polling approach to all items, which reduces overall power consumption while maintaining necessary monitoring quality
2Measurement precision
If polling frequency is increased to improve detection accuracy, then response time to faults is reduced, but resource consumption increases
Solution Approach 1:
The system dynamically adjusts polling frequency based on detected conditions. When abnormal conditions are detected, the polling frequency automatically increases for relevant detection items to improve detection accuracy and response time. When conditions are normal, polling frequency decreases to improve resource efficiency, thus resolving the contradiction between detection accuracy and resource efficiency
3Reliability
If all detection items are monitored with equal priority, then comprehensive monitoring is achieved, but polling efficiency decreases due to unnecessary polling
Solution Approach 1:
The patent segments detection items into different priority levels (first priority, second priority, etc.) based on their importance. This segmentation allows the system to apply different polling strategies to different groups of detection items, ensuring comprehensive monitoring of all items while improving polling efficiency by focusing resources on high-priority items
Solution Approach 2:
The system changes the parameter of polling frequency based on detection item priority. High-priority items receive higher polling frequencies while low-priority items receive lower frequencies, optimizing the balance between monitoring completeness and polling efficiency

AI summary
A battery protection chip, a polling detection method and a polling detection circuit based on a battery protection chip are provided. The circuit includes: a polling signal generator generating first and second selection signals based on a basic clock signal, a plurality of state signals and a priority of a plurality of detection items. An input array selector selects one of a plurality of reference signals and one of a plurality of feedback signals to output to a comparator based on the first selection signal; the comparator compares the feedback reference signals and outputs an indication signal. An output sampler samples the indication signal according to the second selection signal and updates the plurality of state signals according to a sampling result.
