                                         True Cost of Lithium Ion Battery Systems

 

There is a strong tendency in market to confuse cost of “Li-ion cells”, which make up only 40-50% of overall “battery pack“cost. Determine your total cost of ownership and cycle life cost; not the cell cost. The balance of the costs is split between a range of components, with only the margin and warranty share exceeding 10% of the total.There are other factors that contribute to the cost of lithium-ion systems that automakers must take into account when evaluating potential suppliers. One of the most critical and often overlooked attributes that should be considered is how much usable energy a battery yields, which can have a significant impact on battery costs.The battery management system (BMS) is significantly more expensive because it requires more flexibility and mechanism to shift energy to and from the battery frequently and in a wide range of operating conditions. There is also a need to more actively manage the battery cells and state of charge. All these factors increase the specific cost of the battery pack.                          http://www.tacbattery.com/supplier-8456-lithium-ion-cylindrical-battery
