FAQ

Public EV charging stations are typically categorized as either Level 2 or Level 3 DC Fast Chargers (DCFC). Level 2 chargers deliver alternating current (AC) to the EV's on-board charger, which then converts the AC power into direct current (DC) to charge the battery.

In contrast, DC Fast Chargers skip the vehicle's on-board charger entirely and instead provide DC power directly to the EV battery. By circumventing the on-board charger, DC Fast Chargers can provide a faster and more efficient charging experience for EV owners.

The upkeep required for publicly accessible DC chargers is determined by their usage and location. To ensure optimal performance, the cables, plugs, and charger should be periodically inspected for any damage. Additionally, touch screens, card or RFID readers, and software systems should be examined and updated regularly.
With modern chargers featuring advanced connectivity and modularity, many problems can be diagnosed and resolved remotely, further streamlining the maintenance process.

An electric vehicle's charging speed with DC charging can be impacted by various factors. Nonetheless, as the AC/DC converter is present in the charging unit, using DC charging can be notably quicker compared to AC charging. The charging speed with DC charging is influenced by different factors, such as the current charge of the battery, weather conditions, the battery's charging capacity, and the power output. It's worth noting that batteries charge slower in colder temperatures. 

Battery’s current charge
Charging slows down significantly for the final 20% due to battery life and safety measures.

Weather conditions 
Lithium-ion batteries used in EVs are sensitive to cold temperatures, which can negatively impact charging speed.

Power output
The power output of the charging unit affects charging times, with higher power outputs leading to faster charging speeds. For example, charging for 15 minutes at 100 kW and 350 kW power output can provide an additional range of 130 km to 480 km, respectively. Charging for one hour at 50 kW output can add 278 km of range.
