How to charge Tesla Model 3 from battery E3D, E5D and similar E1R, E6R? Up to 80 percent? And to what level to discharge? [answer] • CARS

Tesle Model 3 is currently available in our market with four different types of batteries, which are marked on the approval certificate as E1R, E3D, E5D and E6R variants. Depending on which car we are driving, the ways of charging cars can be different. Here's an overview of how to proceed for each option.

  • Tesla 3, Option E1R, E3D, E5D
  • In the middle of the week, I have 50 percent. Charge or discharge more?

Let's start with the basics: the best and most recent charging instructions can be found in the user manual. If we go too far with something, the machine will also give us a hint. These sources are worth trusting because only they have the current information provided by the BMS battery management system.

And let's move on to specific models:

Tesla 3, variant E6R

Compared to the previous Tesla, it stands out the most. Tesla Model 3 Standard Range Plus, variant E6R made in China and has a 54,5 kWh battery based on lithium iron phosphate cells (LiFePO₄, LFP). Manufacturer recommends fully charge such vehicles (100 percent) at least once a week... Therefore, there is no 80-90 percent “Daily” line on their counters:

When it comes to discharge, LFP cells in the E6R variant should not degrade much when sometimes we go down to 0 percent (gauge value). Under normal use But let's try not to drop below 10-20 percent too often..

Tesla 3, Option E1R, E3D, E5D

Other options E1R (54,5 kWh) and E3D (79 or 82 kWh) i E5D (77 kWh). They appear to be using nickel-cobalt-aluminum (NCA Panasonic) or nickel-cobalt-manganese (NCM LG) cathodes. In everyday use, as Elon Musk states, they can work in the range of 90-10-90 percent, but for mental comfort, it is better to use cycles of 80-20-80 percent.

This also applies to Tesla Model S and X, although we only find NCA cells in them.

> Why is it charging up to 80 percent, and not up to 100? What does all this mean? [WE WILL EXPLAIN]

In the middle of the week, I have 50 percent. Charge or discharge more?

This question is often repeated: To what extent can the battery run out during normal use, which mainly consists of short trips? Up to 50 percent? Or maybe 30?

The answer is not particularly difficult. In general, we can safely operate the car in the aforementioned 80-20-80 range and not worry that the car will stand under the block for several days with the battery discharged by 30-40 percent. BUT keep in mind that Tesla tends to consume a lot of power after activating Sentry Mode, and cold will cause capacity degradation.

Therefore, we advise you not to leave the car under the block on the weekend with the battery discharged to 20 percent or less, it is better to recharge it at least 40 percent. This also applies to any other electric vehicle. To date, experiments and experience show that the battery will last longer if:

• we use lower powers for charging (socket / wall box instead of support or quick charger),
• working cycles are already (for example, 60-40-60 percent instead of 80-20-80 percent).

Of course, the most important thing is that the car serves us well, because it is for us, not us for it.... The battery is supposed to have so much power that we don't have to constantly worry about decreasing range and frantically looking for charging points.
