Solution Overview

Problem

Existing electric vehicles (EVs) require multiple GSM/GPRS modules and a Vehicle Control Unit (VCU), leading to duplication of functionalities, increased costs, and complexity.

Innovation Solution

Eliminate the VCU and integrate a GSM/GPRS module within the battery, enabling the battery to communicate data from the Motor Control Unit (MCU) to external entities, reducing the need for separate modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a VCU and separate GSM/GPRS modules are used in EVs, then data communication functionality is achieved, but device complexity and cost increase

Engineering Contradiction:

Improvedata communication functionalityVSAvoidnumber of modules

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the VCU and GSM/GPRS module into a single integrated unit. The VCU includes both control processing capabilities and wireless communication functionality, eliminating the need for separate modules. This integration reduces device complexity while maintaining data communication functionality between the EV and external entities.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated VCU performs multiple functions: it controls vehicle operations and simultaneously handles telemetry data communication via embedded GSM/GPRS functionality. This multi-functional design eliminates redundant components and reduces overall system complexity while achieving reliable data transmission.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple GSM/GPRS modules are used in EVs, then data communication is achieved, but cost increases

Engineering Contradiction:

Improvedata communication capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines wireless communication functionality into the VCU, eliminating the need for separate GSM/GPRS modules in both the vehicle and battery units.
