The Technical University of Munich has developed a standardized test to compare batteries. together with auto motor and sport Technical university professors have 55 kWh . There are similar sized battery packs with a net capacity of VW ID.3 and in Tesla Model 3 compared. The result: The US electric car maker is slightly ahead of the largest car company in Europe. Tesla allows for higher battery temperatures and uses energy more efficiently.
The researchers used the roller dynamometer of the Technical University of Munich and under similar weather and temperature conditions in actual operation allowed the e-cars to drive similar routes in the city, on country roads and on the Autobahn. In practice, the battery in the Model 3 lasts slightly longer than the ID.3, although the Tesla at 239 kW (325 PS) is almost twice as powerful as the ID.3 at 125 kW (170 PS).
Damage in VW makes itself louder auto motor and sport It’s worth noting that ID.3’s engineers start the cooling at a battery temperature of 33 degrees, up from just 42 degrees in the Model 3. This saves a lot of energy for cooling in Tesla, VW can only partially compensate for this with less rolling resistance. The German electric car has a long range on a country road only at an ambient temperature of 15 degrees, otherwise Tesla is always a little ahead with ten kilometers more range. According to the investigation, the greater range is also due to the fact that the Tesla uses energy more efficiently: the Model 3 has an efficiency of 97 percent under full load, while the ID.3 is only 93 percent, according to the researchers.
The higher permissible battery temperatures in the Model 3 are also worth noting when charging: Tesla expects the lithium iron phosphate battery (LFP) used in the test vehicle to be charged to a maximum temperature of 50 degrees, according to VW Allows nickel-manganese-cobalt cell. (NCM) only less than 45 degrees in ID.3. According to the report, while the Model 3 refreshes from 10 to 80 percent in 26 minutes during fast charging, the ID.3 takes 35 minutes.
Tesla uses a variety of batteries and chemistries, which it manufactures with long-term partner Panasonic and which it buys from suppliers. The lithium iron phosphate battery tested by the Technical University of Munich comes from the Chinese company CATL, which is one of the leading suppliers of e-car battery cells. The LFP technique is robust and comparatively inexpensive, but less efficient than cells with native NCM chemoresistance.
Volkswagen also buys energy storage from CATL and other battery makers, and the Wolfsburg-based company and Tesla also want to make their own batteries in the future. Due to the variety of products used, battery tests from the Technical University of Munich have only limited informational value for other models, but Tesla is generally considered a leader in batteries for electric cars.
