The charging speed of a 30kW charger depends on multiple factors, including the battery capacity of the electric vehicle, the battery status, the output voltage and current of the charger, etc.

Under ideal conditions, the charging speed of a 30kW charger can quickly recharge the electric vehicle, but the specific charging time needs to be considered comprehensively based on factors such as the vehicle model, battery capacity, grid conditions, and the layout and design of the charging pile.

The following is a detailed analysis of the charging speed of a 30kW charger:

I. Charging speed under ideal conditions

Charging efficiency: The 30kW charger directly converts AC power into DC power to charge the car battery, skipping the conversion process of the charger in the car, so the charging efficiency is higher.

Charging time: Generally speaking, for an electric vehicle with a power of about 50 or 60 degrees, if a 30kW charger is used, under ideal conditions, it takes about 12 hours to charge from a low power state to 80%. This is because the charging speed of a 30kW charger is 30 degrees/hour, that is, 30 degrees of electricity can be charged in 1 hour.

II. Charging time for specific models

Battery capacity: The battery capacity of different models varies, so the charging time will also vary. For example, it takes about three hours to fully charge a 100kWh battery pack of an electric vehicle from 0 at 30kW. If it is a 66kWh battery, the time required for charging at 30kW will be relatively shorter.

High-efficiency charging range: The 30%~80% high-efficiency charging range of a DC fast charger generally takes about 30 minutes, and it is estimated to take more than an hour to fully charge from 0. This is because the battery management system (BMS system) of an electric vehicle will adjust the output current of the charger under various factors such as different ambient temperatures and its own battery balance, thereby affecting the charging rate.

3. Protection mechanism during charging process

Overcurrent protection: During the charging process, if the current increases abnormally, such as a short circuit in the charging line or a vehicle battery failure causing current overload, the overcurrent protection function of the charger will start quickly, cut off the charging circuit in time, and prevent damage.

Leakage protection: The charger is equipped with a sensitive leakage detection device. Once a leakage is detected, it will immediately stop charging and issue an alarm to ensure user safety.

4. Other factors affecting charging speed

Grid conditions: A 30kW charger will obtain a large amount of power from the grid when charging. When multiple charging piles are working at the same time, it may cause a certain impact on the local power grid. Therefore, factors such as the carrying capacity of the power grid and voltage fluctuations may affect the normal operation and charging speed of the charger.

Charger layout: The layout and design of the charger will also affect the charging speed. For example, if the layout of the charger is unreasonable, resulting in a long charging line or too many joints and turns, it may increase power loss and charging time.
