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 .

How does doubling battery size affect energy consumption?

In relative terms, the urban commuter experiences the biggest increase in emissions when doubling the battery size (20%). This is due to the more frequent and shorter trips of this user type, which requires more frequent cooling or heating of the cabin and battery and thereby increases the energy consumption of the thermal management system.

Why is a larger battery better than a longer range?

While longer ranges promise autonomy and convenience for the driver, the associated larger battery increases energy consumption and greenhouse gas emissions over a vehicle’s lifetime. Furthermore, it increases the overall vehicle’s costs due to higher purchase price and operational expenses.

Is the unit price of a battery cell based on factory size?

However, a high-volume market for all components of battery cells except cathode active material is assumed , meaning that the unit price of all components in a battery cell except cathode active material are independent of factory size. The latter approach is adopted in this work.

How to simulate a wide range of battery sizes?

In order to simulate a wide range of battery sizes for the same vehicle model, the study uses the Siemens Simcenter Amesim simulation software. The vehicle model data is obtained from a recent test project conducted by the Technical University of Munich (TUM) and from the German car club ADAC database.

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.
