How many Tesla 21700 lithium batteries should I buy for a 72V32Ah electric car?

Introduction How many Tesla 21700 lithium batteries should I buy for a 72V32Ah electric car? Low-speed electric vehicle lithium batteries need to examine the battery core capacity, whether it is 2000 MAH

How many Tesla 21700 lithium batteries should I buy for a 72V32Ah electric car?

Lithium battery for low speed electric vehicle

You need to look at the capacity of the cells. If it is 2000MAH, you need 320 cells, 20 in series and 16 in parallel. it's 3000MAH, you need 220 cells 20 cells in series and 11 in parallel.

Before buying a lithium battery, first check whether the battery cells it uses are grade A. Second, look for a lithium battery. lithium battery produced by a major manufacturer, mature production technology, guaranteed after-sales service, and the market reference price of lithium batteries is 1,250 yuan/KW.H. If you have to travel a long distance, it is best to install a range extender. With it, you won't be afraid of running out of energy halfway and it can help you travel worry-free.

Since the cruising range of four-wheel electric vehicles at low speeds isstill relatively limited and cannot fully meet the daily travel needs of the public, if you want to increase its cruising range, you can install an extended range. Increase its cruising range, increase its range of activities, meet the daily travel needs of the public, and travel back and forth freely, without more difficulty due to lack of power midway.

You can buy the range extender directly from the manufacturer, and they will ship it directly, which will be cheaper. It is necessary to choose a range extender produced by a major manufacturer and a major brand to have all the guarantees in terms of quality, performance, manufacturing and after-sales service. Otherwise, if it is a small workshop type manufacturer, it will be easy to break and there will be no guarantee in all respects.

Recommendations for using prange extender:

It is not recommended to start the range extender when the battery is full. It is generally recommended to start the range extender when the battery is only charged. 30%-40%. There is no particularly good effect when starting when the battery is full. For the sake of respect for the environment, it is recommended to start the range extender when necessary. Battery pollution is more serious than exhaust pollution. It is not recommended to use it when the battery is low on electricity. The range extender starts electrically. If the battery is low on electricity, it may not start.
