Charging Curveball: Navigating Charge Speeds Between Standard and Long Range Tesla Model 3 Batteries

## Charging Speed Differences: Standard vs Long Range Batteries

One of the most important factors to consider when purchasing an electric vehicle (EV) is the charging speed. With Tesla's Model 3, there are two battery options available: standard and long range. In this blog post, we will explore the differences in charge speeds between these two battery types and discuss whether or not it's worth upgrading to a Wall Connector for faster home charging.

### Understanding Charge Rates for Tesla Model 3 Batteries

When comparing the specs on the standard and long-range batteries, some users may be disappointed with the quoted 240V charging speeds. The standard battery has a charge amp capacity of 32A, while the long-range battery has a slightly higher capacity at 40A. This difference in charging speeds can leave potential buyers scratching their heads.

The question arises if these 240V charge specs are tied to the battery itself or the Universal Mobile Charger (UMC) that comes with each respective car. Could it be possible that the UMC included with the standard battery vehicle is set to 32A, while the one included with the long-range battery vehicle is set to 40A? If so, then Tesla might technically be quoting the charge rate of the UMC included with each vehicle rather than the actual battery capabilities. However, this would mean they are producing two different UMCs, which isn't very efficient from a supply chain perspective.

According to Tesla, the home charging rates for each battery type are as follows:

- Standard Battery: 30 miles of range per hour (240V outlet, 32A)

- Long Range Battery: 37 miles of range per hour (240V outlet, 40A)

These numbers indicate that there may indeed be a difference in charging capabilities between the two batteries.

### The Impact of Wall Connectors on Charging Speeds

With Tesla's Model S, opting for a Wall Connector meant that users would benefit from faster charging rates. However, it's unclear if this advantage still exists with the Model 3. If there is no significant difference in charge speed when using a Wall Connector for the Model 3, Tesla may see fewer sales of these units to Model 3 owners.

The press release specifies the charging numbers at 240V and either 32A or 40A power, depending on the battery type. It's possible that the standard battery is limited to 32A home charging, while the long-range battery can handle up to 40A. This would mean that the long-range battery has a charging rate significantly better than the Model S when using a NEMA 14-50 connection.

It's unclear whether the charge rate would be higher with a Wall Connector or if the batteries are simply limited to their respective capacities. There is some hope that connecting a Model 3 to a hardwired Wall Connector might allow for a higher amperage draw, but this remains unconfirmed.

### Final Thoughts

While it appears that there may be differences in charging capabilities between Tesla's standard and long-range batteries, it's important to consider your individual needs when deciding which option is best for you. Additionally, investing in a Wall Connector may provide added convenience even if it doesn't significantly increase charging speeds.

Ultimately, as electric vehicle technology continues to advance, we can expect improvements in charging capabilities across all models and battery types. For now, understanding the differences between standard and long-range batteries can help you make an informed decision when purchasing your next EV.
