Solution Overview

Problem

Existing battery power management systems are complex, costly, and fail to provide sufficient output power when a battery module or charging-discharging module is faulty, requiring shutdown for maintenance and potentially disrupting power supply to critical equipment.

Innovation Solution

An array-type battery power management apparatus with integrated battery and charging-discharging modules, connected via a bus unit, allowing for redundant power supply and hot-swapping of faulty units without shutting down the system, thus maintaining power continuity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If battery modules and charging-discharging modules are separately operated and connected via electric wires or copper buses, then electrical connection is established, but wire material costs increase and wire process becomes complex

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidwire process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the battery module and charging-discharging module into a single integrated unit. The battery stack and charging-discharging circuit board are positioned adjacent to each other within the same housing, eliminating the need for separate wire connections between modules. This integration directly reduces wire material costs and simplifies the wire process while maintaining reliable electrical connection.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If the battery power management apparatus has only one set of battery module and charging-discharging module, then device complexity is reduced, but the system cannot operate when the module is in fault and must be shutdown for replacement

Engineering Contradiction:
Improvesystem configuration simplicityVSAvoidsystem continuous operation capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the battery power management apparatus into multiple independent battery power integration units, each containing a battery module and charging-discharging module. These units are electrically connected in parallel through a bus unit. This segmentation allows individual units to be replaced or repaired without shutting down the entire system, as other units can continue to provide power. The system achieves fault tolerance through this modular segmented architecture.

Inventive Principle:
Principle #1Segmentation

3Reliability

If battery modules are connected to charging-discharging modules via electric wires, then electrical connection is established, but wire material costs increase

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidwire material consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent integrates the battery module and charging-discharging module into a single unified structure where the battery stack and charging-discharging circuit board are positioned adjacent to each other within the same housing. This merging eliminates the need for external electric wires to connect separate modules, significantly reducing wire material consumption while maintaining stable electrical connection through direct internal connections.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An array-type battery power management apparatus includes at least two battery power management apparatuses. Each battery power management apparatus has a bus unit and at least one battery power integration unit. The battery power integration unit has a battery module and a charging-discharging module. The battery module has a first positive conductive terminal and a first negative conductive terminal. The charging-discharging module has a second positive conductive terminal and a second negative conductive terminal. The second positive conductive terminal is directly connected to the first positive conductive terminal and the second negative conductive terminal is directly connected to the first negative conductive terminal, thus directly electrically connecting to the battery module and the charging-discharging module.
