Types of EV Charging Equipment
Electric vehicles (EVs) have advanced significantly time by time. EVs remain more costly than gasoline-fueled vehicles over their useful life. The governments and their EVs policies in some countries are making ease to the people to adopt electric vehicles.
Before we start with anything, let us first look at the battery of the electric vehicles. We will discuss the charging infrastructure, its importance, types and types of EV Charging Equipment
Types of EV Charging Equipment
The cells are only one component of the cost of an installed battery, the cost of installed batteries has declined from around $1,000 per kWh in 2010 to an estimated $250-350 per kWh in 2018. Total battery costs are falling more slowly, as consumers demand EVs with longer ranges and thus larger batteries. Many governments are finding it increasingly difficult to fiscally justify large subsidies to attract buyers.
The lifetime costs of battery-only cars (BEVs), plug-in hybrids (PHEV) and gasoline-fueled internal combustion-engined vehicles (ICE) are using a range of gasoline prices, discount rates, and battery costs. The PHEV is more expensive than the ICE in almost all scenarios, while the BEV is robustly cost-competitive. The reductions in battery costs will still be needed for BEVs to be a viable alternative to ICEs.
Charging infrastructure
Charging infrastructure is the main thing that people are looking for before buying any electric vehicle. The availability of charging infrastructure is the first and important step in the growth of electric vehicles.
Charging infrastructure
Electric Vehicle Chargers-Advantages and Disadvantages
The form this infrastructure will take is still uncertain, with a range of charging technologies currently available and more expected to emerge over the next five years. The alternating current (AC) chargers are best suited for home or office locations and short trips and much faster direct current fast chargers (DCFC) for rapid refuelling in public locations, best suited for recharging on longer journeys.
Charging Challenge
Rapid EV deployment will increase the demand for power, but the existing generating capacity should be able to meet that demand in most areas of the country, assuming that a percentage of that incremental demand occurs in the off-peak hours.
Types of EV Charging Equipment
Electric vehicle supply equipment” (EVSE) comes in two basic varieties. Below are the varieties.
Level 1 and Level 2
Level 1 and Level 2 which uses alternating current (AC), and can draw electricity directly from the local distribution system. All BEVs and PHEVs carry an on-board inverter with limited capacity, to convert AC power to direct current (DC), which is required to charge the battery.
Level 3 and above
Level 3 and above uses DC charging which bypasses the need for an inverter by charging the battery directly and can therefore deliver much more power.
