Electric vehicles are becoming more commonplace around the world. This is driving demand for a charging infrastructure that can support this turning point in transportation.
The individual cost may still be a challenge, but the move to EVs is inevitable. This is change driven by need, rather than the whim of suppliers.
The charging infrastructure supporting e-mobility is less coordinated. This can be viewed positively for those looking to enter the market. Public money is in good supply, and private investment is also high. The underlying technology is not particularly complex, which means the barriers to entry are low.
But it isn't quite as simple as putting a socket in a public location and calling it a charge point. Those that are putting equipment into service are referred to as charge point operators, and they must work with the electric vehicle supply equipment manufacturers to develop a strategy that will support the charging infrastructure as demand continues to increase.
Not all EVs charge at the same rate, and not all charge points deliver the same amount of power. This creates a multitiered landscape of both public and private charging. As most cars are parked for most of the time, private chargers work at a slower rate. But drivers on a longer journey will want to charge as quickly as their vehicle allows. This means public fast DC charging will be in higher demand in service areas, while slower AC charging will be common in places where people spend more time, such as shopping malls.
Installing a fast DC charger in a public area requires more power from the grid. The design of the charge point will also be more complex and potentially more expensive. It will need a DC-to-DC converter rated for continuous operation, and the safety aspects of working with higher power will also impose design constraints.
