Why Is Tesla Only Charging At 16 Amps?

A typical Tesla charger has a charging rate of 40-50 amps which is very fast as compared to the Tesla 16 Amps charging system. This can be more frustrating for Tesla owners who nearly face these types of issues. So, do you know what causes your Tesla to charge at only 16-Amps?

Some of the reasons are highlighted in the second part of the article but here we’ll be explaining a detailed list of causes.

  • Low Amperage Charging Outlet: If you are charging your Tesla with the low amperage charging outlet then it has a high chance that your Tesla will hold a slow charge which may affect the overall charging time of Tesla. The low amperage charging outlet or wall outlet has a limited power source. So, the Tesla charger will get less power and result in slow charging.

  • Old or Less Powerful Cable: Using low or less powerful charging cables may be also one reason behind the slow charging of Tesla. You all know Tesla has one of the sophisticated charging systems and they use high-performance charging cables in support of fast charging. What type of charging cable you are using to charge your Tesla also affected the Tesla charging time. If the cable is damaged and not working properly, it will result in less delivery of power resulting in a slower charge.

  • Fault In The Charging Port Or Charging Electronics: It is very necessary to keep your charging port or charging electronics in good condition for fast charging. The charging system of Tesla can be greatly affected if there will be any issue or fault in the charging port or onboard charging electronics.

  • Using the Same Circuit For another Electrical Device: If you are drawing power from the same charging circuit to charge any other electrical device, then it may also hamper the charging time of Tesla. Connecting multiple electrical devices on the same circuit reduces the available power and results in a slow charging rate. So, to avoid the slow charging of Tesla, never connect too many appliances in the Tesla charging circuit.

How Many Amps is a Tesla Charger?

How many amps a Tesla charger can deliver is highly dependent on the different Tesla models and what types of charging the Model Tesla is using. Different models of Tesla have different chargers and charging power. Every Model has a different capability to accept power. However, sometimes it also depends on the available power supply to the Tesla’s charging system.

Typically, most Tesla Model has an onboard charger and the capacity to accept up to 40 to 50 amps of charging current. The more amps of current allow the Tesla vehicles to charge more quickly as compared to fewer amps of charging current. The charging time may also depend on the available power supply even if you are using a fast charging system of 40 to 50 amps.

Let’s conclude with the help of different Tesla models. A Tesla Model 3 has an onboard charger of 50 amps which can easily charge the battery at the rate of 72 miles of range in a single hour. Just imagine you can cover up to 350 miles by just charging your Tesla Model 3 for 3 hours. The charging circuit of the Tesla Model 3 must be connected to a 240-volt level 2 charging station.

You must be knowing Tesla has widely spread its charging system. Now you can charge your Tesla anywhere you want because it offers both home and public charging. All the chargers are available in different amps depending upon the need of the user or the available power supply.

Tesla Level 2 wall charger is designed for home or business use. The charger is available in 40 amps and 80 amps to facilitate the users with the quick charging system.

You must be wondering why Tesla is working on the supercharger network. The reason is Tesla is allowing all the users to shift over to electric vehicles and enjoy long-distance trips with the help of the fastest charging network. These networks are specially designed for charging vehicles quickly and easily.

How Do I Charge My Tesla and What Are The Basic Rules Of Tesla Charging?

Hell yes, you are a proud owner of a Tesla car but the most critical issue with the Tesla is ranger anxiety, almost all owners of Tesla has range anxiety, and to eliminate the anxiety of the user Tesla is constantly increasing their battery technology as long as possible. To get the best out of the Tesla Range, it is also advisable to use a good charging system as well good charging pattern.

A good charging system and pattern prevent the battery from any further damage as compared to the frequent battery charging pattern. No doubt, the battery of Tesla is packed with lithium-ion which has a higher density than any other battery pack. But you as an owner also have to follow basic rules of charging for increasing the Tesla range. So, let’s see what are the basic rules of Tesla charging.
