BEV Charging Infrastructure Stage 1 and 2 Reports and Tools Booklet

The project objective was to produce a study that highlights the challenges, impacts and solutions for charging infrastructure to operate Battery Electric Vehicles (BEV) underground.  The project provides a report and work booklet relating to Battery Electrical Vehicle (BEV) charging infrastructure.  

The project had two stages, reported as a stage one and two report respectively.  Stage 1 focused on the infrastructure available to industry and the tools required to determine the mine charging infrastructure requirements. Stage 2 looks at the infrastructure recommendations for the industry and specification requirements as well as a two case studies to show how these systems may be implemented.

BEV Charging Infrastructure - Stage 1

Stage 1 of the project provides information and tools to the coal industry to assist with the planning of BEV charging infrastructure into either an existing brownfield or a new greenfield underground coal mine. This report includes the following:

• Section 1 - Introduction - An overview of the project history, project objectives and project focus. Section 1 also lists some key benefits of the project to the coal industry.
• Section 2 - Legislation, Standards & Guidelines - An overview of the key legislation, Australian and International standards and guidelines for BEV charging infrastructure for use in underground coal mining industry in Australia.
• Section 3 - Industry Workshop & Survey - Results from an industry survey of NSW and QLD underground coal mine sites, focusing on general mine information, current size and type of diesel fleets, and how the diesel fleets are utilised at the mine site.
• Section 4 - Battery Electric Vehicles (BEV) - An overview of existing BEV available to the underground coal market in Australia.
• Section 5 - Battery Systems - A review of battery technology history and types of battery chemistry, highlighting advantages and disadvantages of each type.
• Section 6 - Battery Charging Systems - An overview of the current suppliers including the range and specifications of BEV charging infrastructure.
• Section 7 - Metal Mines - A review of BEV that have been installed at metal mines in Australia, and any issues encountered while in operation at the mines.
• Section 8 - Load Flow Study - A high-level load flow study has been completed to determine the expected power load on supply systems for the BEV charging infrastructure. This study includes a load flow study only, and does not cover fault levels, protection, arc flash and harmonic studies as these can only be completed when included in an actual mine site model.
• Section 9 - BEV Charging Philosophy - The BEV charging philosophy is the most important stage when planning for the BEV charging infrastructure requirements on a mine site. This section provides an overview of the process to determine the mine BEV charging philosophy and tools that will assist with this process.

Stage 2 of the ACARP project reviews the following key sections:

• Section 10 - Design / Operational Risk Assessment - The design and operational risk assessment looking at BEV charging infrastructure engineering requirements.
• Section 11 - Power Systems Study - An overview of the power systems studies that should be considered when completing the engineering requirements for new BEV charging infrastructure into a mine site.
• Section 12 - Power Systems Design Review - A review of power system design considerations for power supply transformers required for BEV charging infrastructure.
• Section 13 - Power Limitation Considerations - A review of the requirements to consider for limiting the BEV charging infrastructure charge rates should there be limits on the available power supply infrastructure at the mine.
• Section 14 - BEV Charging Infrastructure (Surface) - Specification considerations for BEV charging infrastructure installed on the surface of a coal mine.
• Section 15 - BEV Charging Infrastructure (Underground) - Specification considerations for BEV charging infrastructure installed in the underground non-hazardous areas of an underground coal mine.
• Section 16 - BEV Charging Infrastructure (Underground - Hazardous Areas) - Specification considerations for BEV charging infrastructure installed in the underground hazardous areas of an underground coal mine.
• Section 17 - On-Board Charging Review - A review of on-board charging options available to suit underground coal mines in Australia.
• Section 18 - Case Study No.1 Underground Highwall Mine - A case study looking at a generalised mine configuration installing new BEV charging infrastructure for a proposed BEV fleet.
• Section 19 - Case Study No.2 Underground Drift Access Mine - A case study looking at a generalised mine configuration installing new BEV charging infrastructure for a proposed BEV fleet.
