Tesla Model 3 (2021) charging curve versus (2019). Weaker, there is also confusion E3D vs E5D [video]

Bjorn Nyland compared the charging power of the Tesla Model 3 (2021) on the Supercharger v3 and the Ionita with the charging power of the Tesla Model 3 (2019). The new car was much weaker, as other restyling buyers have already reported. Where does this difference come from? Is it a different chemical composition of the new cells?

Tesla Model 3 (2021) and (2019) - differences at the charging station

• Tesla Model 3 (2021) and (2019) - differences at the charging station
  • Old and new cells in Tesla batteries
  • The situation gets more complicated: E3D versus E5D

The difference in the charging curve can be seen at a glance: the new Tesla Model 3 only briefly reaches 200+ kW, while the older model is capable of supporting 250 kW. Tesla Model 3 (2019) drops to the charging level of the variant (2021) only when it exceeds 70 percent of the battery. Just that the newer model is only about 57 percent.

Nyland says the TM3 (2021) Long Range has a smaller battery pack with a capacity of roughly 77 kWh, resulting in a usable capacity of just 70 kWh. Larger packs based on Panasonic cells should have Tesle Model 3 (2021) performance. According to youtuber lower charging rates in newer vehicles may be temporary, because the manufacturer may eventually decide to unlock higher powers - Tesla is just conducting reconnaissance in battle.

Charging curves for old and new vehicles are as follows. Blue line - Model 3 (2019):

The situation is so bad that on the fastest Supercharger v3 Tesla Model 3 (2019), it is able to charge the battery up to 75 percent in 21 minutes, while in TM3 (2021) it takes 31 minutes to replenish the energy to the same level. Fortunately V3 superchargers are not very popular, there are none in Poland, and on older v2 Superchargers with a capacity of 120-150 kW, the difference in charging 10-> 65 percent is 5 minutes (20 versus 25 minutes) at the expense of the newer model.

More importantly, Model 3 (2021) is equipped with a heat pump, so it uses less energy while driving than Model 3 (2019). As a result, he has to refill less at the charging station, which reduces the time to 3 minutes. Worth Watching:

Old and new cells in Tesla batteries

Nyland firmly states that the newer version uses elements from LG Energy Solution (formerly: LG Chem), while the older version uses Panasonic. As for the variant (2019), there is no doubt that Panasonic is. But are LG elements in new cars really sold outside of the Chinese market?

We learned about this from several free comments from a person who "works at the Gigafactory." They show that:

• Tesle Model 3 SR + gets new LFP (Lithium Iron Phosphate) cells,
• Tesle Model 3 / Y Performance will receive new cells (which ones?),
• Tesle Model 3 / Y Long Range will have existing cells (source).

This information contradicts Nyland's claims.which connects LG cells to a lower charger.

The situation gets more complicated: E3D versus E5D

As if there weren't enough cell confusion, Tesla diversified battery packs even further. People who received a Tesle Model 3 in Q2020 XNUMX could receive variant E3D with batteries 82 kWh (Performance only?) or the old fashioned way, 79 kWh (Long distances?). On the other side variant E5D it has guaranteed the lowest battery capacity so far 77 kWh.

All values ​​are taken from permits. Accordingly, the useful capacity is also smaller.

This may mean that an old type of battery (E3D) has acquired new cells with a higher energy density or is using existing cells. However, a newer type has also been introduced to the market, the E5D, in which the cells have a lower energy density, which means a smaller battery (source) capacity.

The battery capacity in the Tesla Model 3 Long Range and Performance is assembled in Germany. Pay attention to the graph in the middle, where you can see the dependence of the battery capacity on the VIN.

Fortunately, cars have a heat pump, so less power doesn't mean poorer range. Against:

> Tesla Model 3 (2021) Heat Pump vs. Model 3 (2019). Nyland's conclusion: Tesle = the best electrician
