Solution Overview

Problem

Conventional electric vehicle charging devices are inflexible and computationally intensive, struggling to effectively regulate power delivery in real-time due to limitations in monitoring and processing electrical consumption data from other equipment connected to the same electrical delivery point, leading to inefficiencies and potential overloading of the electrical network.

Innovation Solution

A charging device equipped with an optimization module to construct a charging profile based on electrical consumption forecasts and a regulation module that switches between two operating modes to adjust power delivery according to measured consumption data, optimizing power output to minimize network load and ensure efficient energy distribution.

Solution Approach 1:

The optimization module constructs a charging profile in advance based on forecasted electrical consumption data before the actual charging process begins. This preliminary action allows the system to pre-determine the optimal power delivery schedule, reducing the need for complex real-time processing while maintaining regulation accuracy.

Inventive Principle:

Solution Approach 2:

The regulation module dynamically switches between two operating modes: using the pre-constructed charging profile during normal operation, and transitioning to real-time data-based regulation when discrepancies are detected. This dynamic approach balances computational efficiency with regulation accuracy adaptively.

Inventive Principle:
Principle #15Dynamics

2Power

If conventional real-time regulation based on measured consumption data is used, then power delivery is controlled, but the approach is rigid and computationally intensive

Solution Approach 1:

The system constructs a charging profile in advance that incorporates forecasted consumption patterns, allowing flexible adaptation to expected conditions without requiring complex real-time calculations. This preliminary planning enables the system to be both computationally efficient and adaptable to varying conditions.

Inventive Principle:
