(In 2010, a lithium-ion battery pack cost US$1,183 per kilowatt-hour. Less than a decade later, the price had dropped to nearly a tenth of that at US$156/kWh in 2019, according to BloombergNEF data)
A 0.5C or (C/2) charge loads a battery that is rated at, say, 1000 Ah at 500 A so it takes two hours to charge the battery at the rating capacity of 1000 Ah; A 2C charge loads a battery that is rated at, say, 1000 Ah at 2000 A, so it takes theoretically 30 minutes to charge the battery at the rating capacity of 1000 Ah;
So, if you have a 12-Ah 100-volt battery, its kWh would equal 12 x 100 ÷ 1,000. Thus, it is a 1.2 kWh battery. Other factors that affect cost. The cost of a lithium-ion battery is also impacted by the following: Battery type; Voltage; Amp hours ; Battery type. The cost of a Li-ion battery depends on its chemistry. For example, batteries
Since 2010, the average price of a lithium-ion (Li-ion) EV battery pack has fallen from $1,200 per kilowatt-hour (kWh) to just $132/kWh in 2021. Inside each EV battery pack are multiple interconnected modules made up of tens to hundreds of rechargeable Li-ion cells. Collectively, these cells make up roughly 77% of the total cost of an average
Comparisons between internal combustion and battery electric cars in 2009–2010 found battery costs to be €600(US$764) per kWh (ref. 8) and, most recently, van Noorden reported US$500 per kWh
