Simulation & Technical Design of Regenerative Battery Testing System (Based on SKXD-5V3A-512CH)
Budget: $250 – $750 USD
Project Overview
We are planning to develop a regenerative battery testing system based on the architecture of an industrial multi-channel tester (model: SKXD-5V3A-512CH or equivalent).
The goal is to redesign or upgrade the system conceptually so that energy from battery discharge is not dissipated as heat, but instead captured and stored in a central energy storage battery system, and reused.
We are not limited to any specific implementation method — the freelancer is expected to propose the most suitable architecture.
---
Objective
Design and simulate a battery testing system with energy recuperation, where:
- Battery discharge energy is recovered
- Energy is stored in a central storage battery (e.g., 48V/96V system)
- Energy can be reused for charging other cells or fed back into the system
- System operates efficiently with minimal energy loss
---
Existing Equipment Reference
The system is based on the following type of equipment:
- Model: SKXD-5V3A-512CH
- Type: Multi-channel lithium battery tester
- Channels: ~512 independent channels
- Per-channel:
- Voltage: 0–5 V
- Current: up to 3 A
- Power supply: 3-phase AC 380V
- Current design: non-regenerative (dissipative discharge)
The freelancer does NOT need to replicate this exact machine, but should use it as a reference baseline.

Scope of Work
1. System Architecture Design
- Propose full system architecture for regenerative operation
- Define:
- DC bus structure
- Energy storage integration
- Channel grouping strategy (e.g., 8–32 channels per bank)
- Identify possible integration points for retrofit or redesign
---
2. Simulation Model
Develop a working simulation using one of the following (freelancer choice):
- MATLAB / Simulink (.slx)
- PLECS (.plecs)
- Other professional tools (with justification)
Simulation must include:
- Bidirectional DC-DC converter
- Battery storage model
- Equivalent battery channel bank model
- Control logic (charge/discharge management)
- Power flow visualization
---
3. Technical Design Documentation
Provide a complete engineering package including:
Electrical Design
- Block diagrams
- Detailed circuit schematics
- Converter topology selection (e.g., bidirectional buck-boost, DAB, etc.)
- Component selection (MOSFETs, inductors, etc.)
Control System
- Control strategy (CC/CV, bidirectional flow)
- Control diagrams / flowcharts
System Integration
- How system connects to tester channels
- Energy flow paths
- Protection systems
---
4. Performance Analysis
- Estimated efficiency (%)
- Energy recovery rate
- Thermal considerations
- Comparison vs conventional (non-regenerative) system
---
5. Deliverables
The freelancer must provide:
- Simulation files (.slx / .plecs or equivalent)
- Editable schematics (PDF + source if possible)
- Full technical report (PDF or Word)
- Block diagrams and system architecture
- Explanation of design decisions
---
Important Notes
- This is a concept + engineering design project, not manufacturing
- We are open to innovative approaches
- Preference for solutions that are:
- scalable
- energy efficient
- realistic for industrial implementation
---
Freelancer Requirements

Goal
To develop a foundation design for a next-generation battery testing system that enables:
Energy recovery
Reduced power consumption
Sustainable operation
