How long does it take to charge an electric vehicle from 10% to 80% at a DC fast charger?

The time it takes to charge an electric vehicle from 10% to 80% at a DC fast charger usually depends on several factors, including:

The power output of the charger DC fast chargers usually have different power levels, with common charging powers of 50 kW, 150 kW, 250 kW, and even higher. The higher the power, the faster the charging speed.

Some high-power chargers (such as 350 kW) can charge more power in a short time, while low-power chargers (such as 50 kW) take longer.

The charging capacity of the electric vehicle Different electric vehicles are limited in the maximum charging power they can accept. For example, some electric vehicles may only be able to charge at 50 kW or 100 kW, while high-performance electric vehicles such as the Tesla Model 3 may support higher-power fast charging, such as 250 kW or more. The charging speed is also limited by the battery management system (BMS), especially when charging to a higher charge (e.g., over 80%), which usually limits the charging speed to protect the battery.

Initial state and temperature of the battery The temperature of the battery affects the charging speed. At low temperatures, the battery may charge slower, while at ideal temperature conditions (e.g., around 25°C), the charging speed will be higher. The health of the battery and the remaining capacity will also affect the charging speed.

Rate changes during charging The rate of fast charging usually changes during the charging process. Generally speaking, electric vehicles charge faster at the beginning of charging (e.g., from 10% to 50%), and as the battery charge increases (e.g., 50% to 80%), the charging speed will gradually slow down to protect the battery and increase long-term service life. Charging from 10% to 80% is usually not a linear time process, especially when charging close to 80%, the charging rate will decrease significantly. General estimate: Assuming a 150 kW charging station and the EV is capable of accepting that power (most modern EVs support a maximum charging power of between 100 kW and 250 kW), we can make the following estimate:

EV batteries typically have a capacity between 40 kWh and 100 kWh.

Charging from 10% to 80% means charging 70% of the battery capacity.

For a 60 kWh battery, 70% of the capacity is 42 kWh.

Assuming a charging power of 150 kW, the charging time is approximately:

42kWh/150kW≈0.28hours =16.8 minutes

However, since the charging rate is not linear, the actual charging time may be longer, especially when approaching 80%. Generally speaking, charging from 10% to 80% may take 20 to 40 minutes, depending on the charging power, the electric vehicle's acceptance, and the battery's condition.

Summary: It takes about 20 to 40 minutes to charge an electric vehicle from 10% to 80% at a DC fast charging station. This depends on factors such as the charging station's power, the vehicle's charging capacity, the battery's condition, and the temperature.

In which cases, you would prefer to use a DC-DC charging converter but not a AC-DC charging module?

DC-DC charging converters and AC-DC charging modules have their own advantages and applicability in different situations. Here are some situations where you may prefer to use a DC-DC charging converter instead of an AC-DC charging module:

DC power demand: When your electric device or system mainly requires DC power, a DC-DC charging converter is a more direct choice to avoid the energy loss of AC-DC conversion. Portable electric vehicle charger application: For portable chargers, especially those that require lightweight and portability, DC-DC charging converters may be more suitable because they are generally more compact and lightweight. Battery-based electric vehicle charging system: In battery-based electric vehicle charging systems, DC charging is more direct and efficient, so a DC-DC charging converter may be a better choice. In areas with unstable AC grid power: In areas with unstable power supply, using a DC-DC charging converter can better control and adapt to power fluctuations and improve system stability. Power transmission between batteries: When power needs to be transmitted between batteries, using a DC-DC charging converter can more efficiently achieve DC power conversion and transmission.

In general, when DC power, high efficiency, compact size, or direct battery charging are required, you may prefer to use a DC-DC charging converter instead of an AC-DC charging module.
