Engineering Contradiction Analysis
1Measurement precision
If conventional battery state prediction techniques are used, then the system is simpler to implement, but the prediction accuracy is insufficient leading to unexpected power loss
Solution Approach 1:
The patent applies preliminary action by pre-training the temporal convolutional neural network on historical battery data before actual prediction is needed. The model learns patterns from past battery states, usage conditions, and control protocols during training, so that when prediction is required, the system can quickly generate accurate forecasts without complex real-time calculations. This pre-computation approach enables high accuracy while maintaining operational simplicity.
Solution Approach 2:
The patent replaces conventional mechanical/electrical battery monitoring approaches with an information-processing system using temporal convolutional neural networks. Instead of relying solely on physical sensors and simple circuit analysis, the system uses deep learning algorithms to process battery data, identify patterns, and predict future states. This substitution enables more accurate predictions by capturing complex non-linear relationships that traditional methods miss, while the computational nature of the system allows for efficient real-time operation.
2Productivity
If battery is subjected to faster charging conditions, then the charging speed is improved, but the battery degrades faster reducing its lifetime
Solution Approach 1:
The patent applies preliminary action by using the trained neural network to predict future battery states before charging occurs. The system analyzes current battery conditions, proposed charging rates, and historical data to forecast how the battery will respond to fast charging conditions. This prediction capability allows the system to assess the potential impact on battery lifetime before committing to a charging protocol, enabling informed decisions that balance charging speed with battery health preservation.
Solution Approach 2:
The patent implements feedback by continuously monitoring actual battery behavior during charging and comparing it against predictions from the neural network. The system uses this feedback to refine its understanding of battery responses to fast charging conditions. Over time, the model learns which charging protocols cause the most degradation and which are safer, allowing it to provide increasingly accurate predictions and recommendations that protect battery lifetime while maximizing charging speed when safe to do so.
3Measurement precision
If different battery histories and operating conditions are considered, then the prediction becomes more accurate, but the system complexity increases
Solution Approach 1:
The patent applies universality by training a single temporal convolutional neural network to handle multiple types of input data representing different battery histories, usage conditions, and operating scenarios. The model is designed to process various input formats and conditions through its convolutional architecture, which automatically adapts to different data patterns. This universal approach allows the system to maintain high accuracy across diverse conditions without requiring separate specialized models for each scenario, thereby managing complexity while improving prediction precision.
Solution Approach 2:
The patent replaces manual analysis of different battery conditions with an automated neural network system. Instead of requiring explicit programming to handle various historical patterns and operating conditions, the system uses deep learning to automatically learn and recognize patterns from training data. The temporal convolutional architecture processes multiple input dimensions simultaneously, extracting relevant features and relationships without human intervention. This substitution reduces the complexity burden on the system designer while enabling accurate predictions across diverse conditions.

AI summary
A request may be received to determine a control profile for a device to perform a course of action. The request may include input values characterizing a state of a battery system included in the device and/or the course of action. Fixed parameter values may be determined based on the input values. Prospective control profiles may be determined for the device. The prospective control profiles may share the fixed parameter values and may each have a respective set of variable parameter values that vary across the plurality of prospective control profiles. A battery system state space prediction model may be applied to determine corresponding battery system state space output values. A selected prospective control profile may be determined, and an instruction to execute the selected prospective control profile may be transmitted to a device controller.
