Electrochemical energy storage power station project pricing method and system

The invention discloses an electrochemical energy storage power station project pricing method and system, and belongs to the technical field of energy storage power station pricing. When an existing electrochemical energy storage power station is constructed, no detailed and reasonable project division scheme exists, and the accuracy, rationality and integrity of the manufacturing cost are affected. According to the electrochemical energy storage power station project pricing method, an electrochemical energy storage power station project is divided into a construction project and an installation project; the construction project and the installation project are divided into a first-level single project, a second-level unit project and a third-level branch project; for a single project, pricing is arithmetic accumulation of unit projects of the next decomposition level; cost composition items need to be distinguished for pricing of the unit project, the cost of each composition item is calculated in differen
