Doesn't Panasonic make the batteries for Tesla?
- martinald 7y agoCorrect, and the Tesla Panasonic relationship is really on the rocks (iirc at one point Tesla owed panasonic over US$1billion in payments)
- jdietrich 7y agoTesla own the Gigafactory but lease the manufacturing equipment from Panasonic on a per-cell-manufactured basis. Tesla have just bought Maxwell, a lithium cell and supercapacitor IP company. Panasonic effectively make the cells (through quite a convoluted financial arrangement with Tesla), but Tesla make the batteries, which is a crucial distinction. An EV battery pack is inordinately more complex than a bundle of li-ion cells. https://electrek.co/2019/05/16/tesla-completes-maxwell-acquisition-battery-technology/ https://electrek.co/2019/05/16/tesla-completes-maxwell-acqui...
- Phlarp 7y agoDo you have any links on how the batteries are more than complex than a bundle of li-ion cells? Is the complexity in the systems to monitor voltage, temp, resistance and such of each cell and distribute load or outright fuse off weakened cells? I don't doubt you, but I would love to learn more.
