6 FAQs about [Photovoltaic energy storage lithium battery depreciation]

Do lithium batteries have a depreciation cost model?

A quantitative depreciation cost model is put forward for lithium batteries. A practical charging/discharging strategy is applied to battery management. The depth of discharge of the battery storage is scheduled more rationally. The proposed strategy improves the cost efficiency of lithium batteries in MGs.

Does a photovoltaic energy storage system cost more than a non-energy storage system?

In the default condition, without considering the cost of photovoltaic, when adding energy storage system, the cost of using energy storage system is lower than that of not adding energy storage system when adopting the control strategy mentioned in this paper.

What is battery depreciation cost?

Accordingly, the battery depreciation cost can be divided into two part: the fixed cost and the controllable cost. For the fixed part, the aging process is inevitable, and a battery has a finite calendar life. For example, once a battery is installed, it will be scrapped after certain years even if it has not been put into operation.

How much does a photovoltaic and energy storage hybrid system cost?

The purpose of this paper is to design a capacity allocation method that considers economics for photovoltaic and energy storage hybrid system. According to the results, the average daily cost of the photovoltaic and energy storage hybrid system is at least 5.76 $.

What factors affect battery depreciation cost?

Some factors are independent of the dispatch strategy such as the ambient temperature and cumulative usage time. While some are controllable, such as the charging/discharging strategy and the DOD in a cycle. Accordingly, the battery depreciation cost can be divided into two part: the fixed cost and the controllable cost.

Does lb management method affect battery depreciation cost?

For further analysis of the economical impact of LB management method on MG, operational costs of the two methods are compared in Table 6. When considering battery depreciation cost under the proposed method, the average DOD of LB groups is 31.11%, lower than 80% under the traditional method.
