At present, most electric car battery voltages processed by electric vehicles; 36V, 48V, 60V, 72V. But the battery capacity is more; 10ah, 20ah, 30ah,……Or until 400ah, even even bigger, theoretical can be infinite, but as electric bicycles, 100A is big enough, running out of sale is also enough. Buy capacity size based on your actual needs.
Lithium-ion batteries are close to several tight indicators to meet; 1, security: 2, charge and discharge, 3, high, low temperature charge, 4, volume weight, 5, battery energy density. Combined with the above decomposition, it is a good choice to use a lithium iron phosphate ion battery in the southern part because the lithium phosphate is afraid of cold, and the charge and discharge current at the time of 10c is 50% when the temperature is 25c, that is, the ambient temperature 25c You can ride 40km, but the ambient temperature can only ride 20km when the temperature is 10c. There is no cold weather in the southern region, the colder is then 1-2 degrees.
Extreme weather is not a few days, no relationship. The most primary is that the lithium iron phosphate ion battery is high, and it is much higher than the three yuan lithium safety. Lithium phosphate ion battery life is 1.
5 times that of the ternary lithium ion battery. The three-yuan lithium-ion battery is suitable for the northern region, and the three yuan lithium is also afraid of cold, but it will be much better, and the three yuan lithium is below the minus 30C. But the three yuan lithium is afraid of heat, it is easy to end out of control, causing high temperature, fire explosion.
So don't be exposed in the sun during hot weather. .
