How Does Electric Vehicle Charging Work?
AC Charge vs. DC Charge Explained
Electric vehicles (EVs) can be charged using two current types: Alternating Current (AC) or Direct Current (DC) where charging via AC is the most accessible form of charging. This method involves bringing power from the grid to the vehicle before going through the onboard charger which converts the AC to DC. Unfortunately, this method results in slower charging speeds which is not a problem for home and workplace charging stations. DC charging, however, eliminates the onboard charger and supplies the battery with direct current. This leads to faster charging, making it ideal for public fast-charging stations where quick turnarounds are preferred.
Charging Speed: How Fast Can an Electric Vehicle Be Charged?
An electric vehicle’s (EV) charging speed is determined by multiple factors, which include the charger type, the vehicle battery capacity, and the maximum charging speed of the EV. AC chargers like Level 1 and 2 charge at low rates of between 2-22 kW which may take several hours to fully charge an EV. On the other hand, DC fast chargers can provide power between 50 to 350 kW enabling charging to 80% within 20 to 40 minutes depending on the vehicle model. It is also important to keep in mind that ultra-frequent use of high-speed charging may be detrimental to your battery health in the long run.
Types of Charging: AC and DC Charging Piles
Due to its economical nature and integration with both private and commercial energy systems, AC charging piles are widely deployed. They are best suited for overnight charging and areas where the time required to charge an electric vehicle (EV) is not a critical factor. On the other hand, DC charging piles are geared towards serving high-demand regions like rest areas along highways and city centers, where quick recharging is critical. DC charging piles provide ultra-fast charging made possible by innovations such as liquid-cooled cables and advanced safety systems. These charging piles ensure that modern EVs with high battery capacities can be adequately supported. The deployment of both types of charging piles is essential in meeting the different expectations of users, and therefore, the adoption of EVs.
