How to calculate the charging time for Tesla Model 3 Dual Motor?

The charging time for the Tesla Model 3 Dual Motor depends on several factors, including the charger's power, battery level, and the type of power supply. To determine how long it will take to charge, you should take into account the main parameters of the electric vehicle and the capabilities of the charging station.

Charging station power and charging speed

The charging speed directly depends on the power of the mobile charging station. The higher the power, the faster the battery charge is replenished. The Tesla Model 3 Dual Motor supports alternating current (AC) charging up to 11 kW, so the mobile charging station must be able to match this capacity. At 11 kW, charging from 0 to 100% can take approximately 7 hours, while at lower power levels, such as 3.7 kW, the process will take more than 20 hours.

Formula for calculating charging time

The approximate charging time can be calculated using the formula:

• Charging time (hours) = Battery capacity (kWh) ÷ Charger power (kW)

For a Tesla Model 3 Dual Motor with a 75 kWh battery and a 7.4 kW mobile station, this calculation will look like this:

• 75 ÷ 7.4 ≈ 10 hours

This figure may vary depending on the charge level at the start of the process and the efficiency of the charger.

Effect of charge level and efficiency

Charging is faster when the battery is low and gradually slows down when the charge level reaches 80-90%. This is due to the peculiarities of lithium-ion batteries, which slow down the charging process at the last percentage to preserve battery life. Therefore, charging from 10% to 80% is usually much faster than the last 20%.

Influence of temperature and other factors

External temperature and battery condition can also affect charging speed. In cold weather, the battery may need to be preheated, which increases the overall charging time. It is also important to take into account possible power losses in the grid, which can affect the actual charge rate.
