Tesla Model 3: LFP battery prone to cold?


The first Tesla Model 3 Standard Range Plus (SR +) from China have now arrived in Europe. But the new battery with LFP cells shows weaknesses at the current low temperatures according to initial reports from the Chinese media. However, the sources are thin.

In China, the Model 3 SR + with LFP cells has been with the first customers since October. According to a report by the Chinese car portal d1ev, which other media have picked up in English and German, initial experiences from some new buyers show that the range of the model is significantly limited in the current cold temperatures and that the battery is in agreement Cases does not let load to 100 percent. The source situation, so much should be said, is currently difficult to verify. The auto portal attributes the problems to the fact that the LFP project was hastily launched in twelve months, “some tests were dispensed with,” it says. Since the first Model 3 SR + with LFP cells are now also arriving in Europe, there should soon be empirical values ​​from these areas.

We remember: On October 1, Tesla had reduced the base price of the Model 3 in China by eight percent, which was due to the use of the new, cheaper LFP battery cells from CATL. Because according to the configurator on the Chinese Tesla website, the range of the Model 3 SR + increased to 468 kilometers at the same time – mind you in the NEDC that is common in China.

The lithium iron phosphate batteries have the advantage that they are significantly cheaper and more robust than lithium-ion cells with NCM or NCA cathodes. They are a little heavier with the same capacity, but their energy density is now sufficient for Tesla to equip the smaller models with the cheaper cells. Before October, the majority of the Model 3 NMC cells from LG Chem built in Shanghai were built into the majority, while cells from Panasonic were used in the rest.
