Design of an off-grid EV charging system for remote national parks in Finland

Abstract

Off-grid charging systems are crucial for electric vehicles (EVs). Not only can they provide an environmentally friendly way of traveling and reduce the impact on the ecological environment, but they can also provide reliable charging guarantees for vehicles in emergency situations such as extreme weather or natural disasters (such as floods and earthquakes). More importantly, off-grid charging systems rely on the use of renewable energy, which helps promote the popularization of clean energy, thereby actively responding to climate change, reducing greenhouse gas emissions, and promoting sustainable development. In addition, although off-grid charging systems may require higher technical and financial investments in the early stages, in the long run, their operating costs are extremely low, and their energy sources are renewable and free, making them an economically viable and sustainable development solution.

This thesis is devoted to designing a solar off-grid electric vehicle charging system with stable energy supply and storage capacity, while also having good environmental adaptability. However, there are many challenges in building charging systems in remote areas (national parks), especially since these areas are usually far away from the power grid. This thesis selects a remote national park as a case study to design an off-grid electric vehicle charging system. In addition to technical issues, this design will also consider charging issues.
