Integrated Battery Management PCB for Centralized Charge Power Control

Solution Overview

Problem

Current battery management systems occupy a large space and incur high costs due to the need for independent power supply and communications lines for each battery control unit, which are not efficiently integrated.

Innovation Solution

Integrate the direct current converter, sampling module, and monitoring module on a single printed circuit board to reduce the need for hardwired cabling and power supply to individual battery control units, allowing for centralized management and reduced space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If independent power supply and communications lines are provided for each battery control unit, then reliability of battery management is improved, but space occupation and system costs increase

Engineering Contradiction:

Improvebattery management reliabilityVSAvoidspace occupation

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent combines multiple battery control units into a single integrated control unit that can manage multiple battery packs. This consolidation eliminates the need for separate power supplies and communications lines for each control unit, thereby reducing space occupation and system complexity while maintaining reliable battery management functionality through centralized control architecture.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated control unit is designed with multi-functional capabilities to perform battery management tasks for multiple battery packs simultaneously. This universal design allows a single control unit to replace multiple dedicated control units, reducing the overall number of components needed and consequently decreasing the space required for power supplies and communications infrastructure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A battery management system is provided in this application, which includes a monitoring module and a sampling module. The sampling module performs sampling on an operating parameter of a direct current converter to obtain target sampling information, and sends the target sampling information to the monitoring module. The monitoring module receives the target sampling information sent by the sampling module, and sends the target sampling information to a central monitoring unit, so that the central monitoring unit determines target charge power for charging an energy storage battery by a power conversion system PCS; and receives a first control instruction sent by the central monitoring unit, and controls the direct current converter to adjust charge power for charging the energy storage battery by the power conversion system PCS to the target charge power.
