What specifications does a generator need to charge a Tesla?

An alternator wouldn’t be able to charge a Tesla because it requires a specific type of charger called a Level 2 charger. The Tesla Model S and Model X vehicles come with an adapter that allows the vehicle to connect to a Level 2 charger, which typically operates at 240 volts and provides a charging rate of between 20 and 80 miles per hour of charge, depending on the charger’s output.

The Tesla Model 3 and Model Y can also use a Level 2 charger, but they come with a built-in charger that can plug into a standard 120-volt household outlet, although this method is much slower than a Level 2 charger.

Conventional generator types

The prices of non-inverter generators vary based on the type of outlet they have (L5-30 and L14-30), but that’s not what we require. The Tesla gas generators that suit our needs predominantly feature NEMA 5-20 outlets (which can use the regular 5-15 plug). L5-20 and TT-30 outlets are not as prevalent, and L14-30 outlets are even less common.

NEMA 5-20 outlets can provide power at a maximum rating of 20 amps, 120 volts, and 2400 (1920) volts, and can fuel your Tesla for a few miles. They are a dependable power source for urgent situations where you need to reach the closest to you power plant, but they won’t last for a few days.

Since Tesla cars use specialized outlets, their connections move to become compatible with NEMA outlets. Older Tesla models utilized 14-50 and 5-15 connections. At the same time, more recent models can only use Gen 2 and Nema 5-15 outlets (which can use Nema 5-20 outlets).

Securing a fast charge

Using the MPH parameter, what is the estimated charging time for the Tesla Model 3 after one hour of charging from a specific outlet?

To charge the battery up to 60%, it is suggested to utilize the appropriate generator for a minimum of 15 hours.

Power restriction and adequate charge

In a workplace setting, establish a boundary for the amount of electricity used to initiate the charging of your car. Begin with the smallest possible amount and gradually raise it to 20 amps (or higher, based on the type of portable generator) within a few minutes.
