How are the costs of a complete battery system calculated?

The costs of a complete battery system, based on cathode active material price scenarios calculated in the work, are represented by a linear regression that accounts for economies of scale. The costs for the battery system were differentiated into cost types, but not into process steps .

Can battery costs be forecasted?

Within this transformation, battery costs are considered a main hurdle for the market-breakthrough of battery-powered products. Encouraged by this, various studies have been published attempting to predict these, providing the reader with a large variance of forecasted cost that results from differences in methods and assumptions.

Are battery cost models accurate?

This method can, however, lead to inaccuracies. Battery costs have decreased significantly over the last decade , which may then lead to overestimation of final costs in current calculation models by using old cost data. Third, models were constructed that establish an independent architecture.

How much does a battery cost?

The paper gives a detailed overview of the cost types in both batteries in a cost breakdown. Their methodology includes learning curves. These learning curves are abstracted from current and estimated future global electric car numbers. For the year 2020, the publication assumes a battery sales price of between 130 and 200 USD per kWh .

What is a modifiable cost model for lithium-ion battery cell chemistries?

Considering the available state-of-the-art bottom-up cost models, Wentker et al. presented a modifiable cost model to estimate cathode active material (CAM) costs for ten sorts of lithium-ion battery cell chemistries based on real-time prices of raw materials.

How does the review contribute to the field of battery cost modeling?

The review contributes to the field of battery cost modeling in different ways. First, the review provides a detailed overview of the most relevant studies published in the field of battery cost modeling in the recent years. Second, we introduce a framework for the evaluation of future cost models.
