6 FAQs about [Battery cost estimation table image]

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 .

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 are battery storage costs?

Values range from 0.948 to 1.11. Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.

Do battery costs scale with energy capacity?

However, not all components of the battery system cost scale directly with the energy capacity (i.e., kWh) of the system (Fu, Remo, and Margolis 2018). For example, the inverter costs scale according to the power capacity (i.e., kW) of the system, and some cost components such as the developer costs can scale with both power and energy.

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.

When are battery cost projections updated?

In 2019, battery cost projections were updated based on publications that focused on utility-scale battery systems (Cole and Frazier 2019), with a 2020 update published a year later (Cole and Frazier 2020). This report updates those cost projections with data published in 2020 and early 2021.
