Investment Cost Analysis of 90kW Electric Vehicle Charging Stations and Influencing Factors

Investing in 90kW electric vehicle charging stations requires detailed cost calculations not only for the charging pile but also for the transformer station and accompanying electrical infrastructure.

Cost of 90 kW Charging Pile

The investment cost of a 90kW electric vehicle charging station depends greatly on the price of the 90kW fast charging piles. These piles not only require advanced technology to ensure fast charging speed but also need safety mechanisms and intelligent management. Choosing and installing the appropriate charging pile can optimize the initial investment cost as well as the long-term operating costs. Therefore, careful consideration is needed to effectively combine budget with technical requirements.

An important factor when investing in a fast charging station is the cost of the 90 kW charging pile. This includes not only the cost of charging equipment but also many other influencing factors.

Equipment and Installation Costs

• Equipment Price: The 90 kW charging pile costs from 180 million to 400 million VND, equivalent to charging piles of 60 kW and 120 kW capacity. This cost similarity is due to the same nominal power range of the equipment.
• Installation and Accessories: The cost of installation work, cable laying, protective boxes, and electrical certification ranges from 10 million to 30 million VND. These factors can vary depending on the installation location and the distance to the main power source.

Management and Maintenance Factors

• Separate Electric Meter: If a separate measuring device is needed for the 90 kW charging pile, additional costs range from 2 – 5 million VND.
• Management Software: For smart charging management, software systems may have license fees from 5 to 20 million VND, depending on the management functions provided.
• Maintenance Costs: To keep the system stable, regular maintenance costs about 500 thousand to 1 million VND per year, depending on the maintenance contract.

Auxiliary and Legal Factors

When setting up a 90 kW charging pile, the necessity of auxiliary infrastructure like a transformer station is considerable. The cost of building a new transformer station can rise to several hundred million if required by the construction site. Additionally, legal procedures such as electrical safety certification and building permits can increase the cost, depending on the local regulations.

Overall, the investment cost for a 90 kW fast charging pile is approximately 200 – 450 million VND or higher, including equipment, installation costs, and other arising factors.

Cost of Transformer Station and Electrical Infrastructure

A significant part of the investment cost for a 90kW electric vehicle charging station comes from building the charging station’s electrical infrastructure and transformer station. To support the large power required by the charging pile, businesses must invest in appropriately powered transformer stations as well as standard-compliant electrical infrastructure. Adequate preparation in terms of infrastructure ensures stable and safe operation for the charging system. Investing in the right type of transformer station not only extends the equipment’s life but also optimizes operating costs.

The Cost of Transformer Station and Electrical Infrastructure is an essential factor that directly affects the business’s investment decisions in the construction and energy sector. This cost is influenced by factors such as the station’s capacity, type of station, materials and equipment, installation location, and current technical standards.

The cost of the transformer station varies according to capacity and station type. For example, with a capacity of 100 KVA, the cost of a frame station is around 283 million VND, while a steel pole station is 322 million VND, and a kiosk station costs 512 million VND. For larger capacities like 1500 KVA, the cost can exceed one billion VND. This unit price can change depending on the design features, used materials, and does not include VAT, transportation, and separate installation costs.

Materials and equipment also play a significant role in constituting the cost of transformer station installation. Some primary equipment includes transformers from brands like Thibidi and Sanaky, Cadivi electrical cables, and switches from Mitsubishi and Schneider. These devices must be carefully selected to ensure quality and efficient use.

When installing the station, costs can increase depending on the site’s location and the project’s complexity. Usually, installation costs are not included in the equipment purchase price, so investors need to consider the total costs, including installation and transportation of materials.

Regarding regulations, investors must comply with the electricity industry’s standards, especially when consuming large power capacities. Installing a separate transformer station not only meets high power demand but also plays an important role in ensuring the safety and efficiency of the system.

Operating and Management Costs

Besides the initial investment cost, operating and management costs of the charging station also play a key role in considering the total investment cost of a 90kW electric vehicle charging station. This includes maintenance costs, intelligent electrical system management costs, and other labor costs. A good management system can help optimize energy consumption, thereby reducing the pressure on electrical infrastructure and saving long-term costs for businesses.

Operating and management costs are an indispensable part of any business operation, especially for electric vehicle charging stations. To achieve optimum efficiency, managing these costs needs to be carried out seriously and strategically.

Firstly, personnel costs for management play a crucial role in maintaining the continuous operation of the charging station. These include not only salaries and bonuses but also allowances, social and health insurance. Training and developing management staff is also crucial to enhance work efficiency.

Secondly, management material costs represent expenses for office supplies, documents, and daily work support tools. Additionally, materials for repairing and maintaining fixed assets are also included in this category.

Next is office equipment costs, including the purchase and maintenance of equipment like computers, printers, and other office furniture. These are unavoidable operating costs for charging stations to maintain an effective working environment.

Depreciation costs for fixed assets are also a factor to consider, including depreciation of long-term equipment and machinery. Businesses need to calculate carefully to optimize these costs.

Moreover, other expenses such as lease payments, various taxes and fees need to be accurately forecasted to avoid significantly affecting the budget.

Regarding operating costs, we can see that they are mainly divided into fixed and variable costs. Fixed costs are generally expenses that do not change with production volume, such as rent and management staff salaries. Conversely, variable costs change with production, such as raw materials and direct labor.

The common formula for calculating operating costs is:

[ \text{Operating Cost} = \text{Revenue} – \text{Other Operating Income} – \text{Cost of Goods Sold} ]

In summary, operating and management costs need to be tightly controlled to ensure the charging station operates efficiently while optimizing energy consumption to reduce pressure on the electrical system. This also contributes significantly to the business’s sustainable development strategy.

Investing in a 90kW electric vehicle charging station can open up many technical benefits and market opportunities. A detailed investment plan helps businesses optimize costs and enhance efficiency, leading to long-term profitability and competitive position.
