The video shows how we have achieved 2% or less degradation of our Batteries in one year.
Read MoreProducing a 75 kilowatt-hour battery for a Tesla Model 3, considered on the larger end of batteries for electric vehicles, would result in the emission of 4,500 kilograms of CO2 if it was made at Tesla's battery factory in Nevada. That’s the emissions equivalent to driving a gas-powered sedan for 1.4 years, at a yearly average distance of 12,000 miles, but if the battery were made in Asia, it would produce 7,500 kg of CO2, or the equivalent of driving a gasoline-powered sedan for 2.4 years.

They are compared on parameters like energy density, safety, life span etc. One can select the battery that is best suited for their use. Lithium Ferro Phosphate are the best if you are looking for cheapest and safe. One may opt for NMC battery if the space and weight is a concern though they are recommended only in cold climate for safety point of view. They can cause fire and blast if not used properly.

01. Passive Balancing: The primary advantage of passive balancing is the simplicity and hence, lower cost.
The drawbacks are: Energy is wasted as heat, and Battery pack life could be shorter.
02. Active Balancing: This active cell_balancing circuit has a lower balancing time,
increase battery life and no range anxiety. However, this equalizing
circuit has a huge cost and complex system.
Battery Shelf Life, like calendar life, is the time an inactive battery can be stored before it becomes unusable, usually considered as having only 80% of its initial capacity.
Battery Cycle Life is defined as the number of complete charge - discharge cycles a battery can perform before its nominal capacity falls below 80% of its initial rated capacity. Key factors affecting cycle life are time t and the number N of charge-discharge cycles completed. There are many more complex factors which can also influence performance.
