According to the International Energy Agency (IEA) there has been a positive incline in the number of chargers available in the infrastructure. Up nearly 40% since 2015 the incline has been riding uphill. China no doubt has been the biggest producer when it comes to EV.
Below is a graph of the number of kilowatts per charge when it comes to EV. The United States has about one kilowatt per charge verses that of New Zealand's point seven kilowatts.
The International Energy Agency says this about the graph above: "The number of EVs on the road increases, the EV-per-charger ratio can help assess the suitability of the charging network. The charger power (kilowatts [kW]) per EV is an essential metric, since fast chargers can serve a higher number of EVs compared to slow chargers. The suitable number of chargers per EV depends on a number of factors, including: housing stock, average distance travelled and population density. PHEV users require less public charging than BEVs. Therefore, it is not trivial to determine a suitable availability metric."
Above is a chart that shows charging by type and location in the United States. (In thousands) As you can see the highest level of available chargers is the level two charger. This charger runs faster than that of the level one but is not as difficult to install as the level three.
