Should we wait for the 4680 batteries in Tesla vehicles?
Recently, Tesla announced that it has produced 1 million of its next-generation 4680 battery cell at its pilot factory in California. Tesla employees celebrated the milestone of one million 4680 cylindrical lithium-ion battery cells on Feb 19 in Fremont.
It’s said that the new cell design would provide five times the energy with six times the power while enabling a 16% range increase. The 4680 battery is a Li-ion battery named after its 46mm × 80mm cylindrical size (diameter × height). When compared to 21700 size and 18650 type cells, the height and diameter both are larger.
It seems the biggest advantage to this battery is that it has a very fast charge time. INSIDEEVs calculated charging time from 10% to 80% with the 4680 pack was reduced from 25 minutes to 15 minutes. If you only need a 50% charge, you can be done in 7 minutes. That’s almost as fast as gas.
Should we wait for the model Y with the new 4680 batteries coming?
Some argued that it will be an evolutionary change not a revolutionary change, the main goal of updating batteries is to reduce cost, the car won’t make any significant change on charging time, range, etc. They all get minor upgrades every year, also, that needs a test time to prove the performance of new batteries. In a word, the upgrades are negligible for people to wait, plus with an uncertain delivery time.
Therefore, the best time to buy a Tesla is when you can, so you could enjoy the benefits of ownership once you get the car.
