Charging Time for Electric Vehicles with Fast Charging Stations (DCFC): What You Need to Know
With the increasing adoption of electric vehicles (EVs), charging time has become a major concern for both drivers and businesses managing fleets. Whether you’re an individual or a business, understanding how charging works and the available options is essential. This ensures a smooth and cost-effective experience. This article explores the different types of fast charging stations and their characteristics, with a focus on the fast chargers offered by Chaevi.
The Difference Between 400V and 800V Batteries in EVs
One key factor influencing the charging speed of electric vehicles is the type of battery. Most EVs use 400V batteries, while some recent models have 800V batteries. This voltage difference directly affects the charging speed. In fact, a car equipped with an 800V battery can achieve charging power (in kW) that is twice as high as a car with a 400V battery, provided the charging station delivers the necessary power in kW.
It’s important to note that it’s the EV that determines its charging speed, rather than the charging station itself. Thus, even with a powerful charging station, the charging time will depend on the voltage of the EV’s battery (400V or 800V), the battery capacity (kWh), the state of charge (SoC), temperature, and other external factors.
Here’s a Simple Way to Calculate Charging Time for Two EVs (400V and 800V Batteries) with the Chaevi Supersonic 400 kW Charger:
1 – Calculating the number of kW that both EVs can accept
- EV battery voltage = 400V and 800V
- Charging station cable amperage = 500A
400V x 500A = 200,000W (200 kW)
800V x 500A = 400,000W (400 kW)
2 – Calculating the charging time for these two EVs based on battery capacity (50 kWh)
50 kWh / 200 kW = 0.25 hours (15 minutes – EV with 400V battery)
50 kWh / 400 kW = 0.125 hours (7-8 minutes – EV with 800V battery)
Please note that this is a quick and approximate calculation, and other factors can influence charging time.
