One major critique of the public charging stations is their high costs and one major critique of home chargers are their installation prices and chargers itself are expensive.

Why are they so expensive in Malaysia when China has hundreds of company mass producing it ? Aren’t they the same as handphone chargers ? There are so many different types of chargers, how do I know which is the most suitable for me ?

All these are questions to be answered as we go along in our series of youtube videos and articles. For now we are going to explain why EV chargers in general are expensive.

The Factors That Make EV Chargers Expensive:


There is a range of factors contributing to the high costs of EV chargers which make them more expensive than their gasoline counterparts, including:

  1. High Power Output:
    Charging speeds can vary from slower Level 2 chargers (3-7 kW) to fast DC fast chargers (50-400 kW). The high power output required for fast charging makes it necessary to use expensive, specialized components to convert AC power to DC power safely. The charger is also required to have robust safety features, which escalates the equipment’s overall cost.
  2. Safety:
    To ensure safety, EV chargers need to have several safety features like thermal management, ground fault detection, and current limiting. Further, since public charging stations need to manage high currents, charger design should meet the highest safety standards. Safety features add an extra layer of complexity and costs to EV chargers.
  3. Installation and Infrastructure:
    Public charging stations require additional infrastructure like conduits, cable trays, transformers, switchgear, etc. to the existing electrical distribution infrastructure. These infrastructure changes raise installation costs. Moreover, for high-output DC fast chargers, upgrading the power distribution infrastructure to handle the increased power requirements will escalate costs.
  4. Maintenance Costs:
    Public charging stations experience high usage, which makes it necessary to have regular maintenance. Maintenance costs of EV chargers include cleaning, repairs, and replacement of parts, among others.

The Cost Breakdown of Different EV Charging Infrastructure Components: An In-Depth Analysis

Electric vehicle (EV) charging infrastructure is composed of several components that work together to deliver electricity from the charging station to the EV. Understanding the cost breakdown of these components is essential for businesses and individuals looking to install EV charging stations.

In this article, we will examine in detail the primary components of EV charging infrastructure, such as the EVSE, the charging cables, and the connectors.
