How do you use 18650 battery to make 60v electric vehicle?

If we use 18650 lithium-ion battery to make 60 V electric cars, it will take at least 192 batteries.

Specific solution: use a single battery spot welding machine to weld the 18650 battery by nickel

Every 12 batteries in parallel, as a group, and then 16 this set of batteries in series, is close to the 60 v40ah.

Every 12 batteries in parallel, the capacity of 12 * 3400/1000 = 40.8 AH;

16 group in series, the voltage is 16 * 3.7 = 59.2 V

Total demand: 12 * 16 = 192

Special remind, lithium batteries on voltage is very sensitive and must match on reliable battery protection board device can use.

You didn't consider the problem of voltage. Section 18650 rated voltage is only 3.7 V batteries, and electric vehicle battery pack at least 48 V (36 V rarely), about 13 section 18650 together battery voltage to achieve. So according to your connection, need 130 knots18650 battery every 10 batteries into the battery pack, that is, in parallel, then 13 groups such batteries together can, so as to achieve the capacity of 48 v30ah.Regular brand 18650 batteries, section 130 of the price must be thousands of yuan.

This is assembled a set of 18650 electric cars all lithium battery materials, including stainless steel battery pack

The assembled group 18650 electric cars need material in lithium-ion batteries

This is the accessory material, wire fabric heat shrinkable film, there is also a voltmeter, voltmeter to judge the battery pack battery box above

The assembled group 18650 electric cars need material in lithium-ion batteries

18650 battery clapboard and fixed bracket, a protection board, lithium batteries must have protective plate, otherwise one is discarded

The assembled group 18650 electric cars need material in lithium-ion batteries

The key is 18650 batteries, electric vehicle must choose power batteries

The assembled group 18650 electric cars need material in lithium-ion batteries

Manufacturer of straight hair, batteries have to buy the real thing, copycat manufacturers of batteries, life is short, and the failure rate is quite high

The assembled group 18650 electric cars need material in lithium-ion batteries

Finally put into the battery box, stainless steel is better

The weight of the battery pack

The Yangtze domestic 18650 lithium battery, the test range was quite good, the price is very cheap 4.5 yuan a day, for there is no spot welding machine assembly is difficult, today to do a use soldering iron to make the battery pack

The protection plate, because it is a small electric, board does not need to how much current, is not expensive 60 yuan

Bat also bring balance so charge can ensure each battery

To line up, the first into the battery box just likes this, much lighter than lead acid. This way, one hand can bring electric vehicles, can upstairs is not afraid of being stolen

Copper to the punch, and welding, because copper conductive good, long time will not rust

Tin on this, a second one, quickly, the premise is that electric power is greater than 60 w, low Power is difficult

And to burnish it

Such good welding, assembly the battery storehouse and then it can be used normally.
