Abstract

The invention discloses an energy storage system of a power battery for an echelon utilization vehicle. The energy storage system comprises an echelon utilization battery management system, a bidirectional energy storage converter, a power control system, an intelligent power distribution system and a monitoring dispatching system, wherein the echelon utilization battery management system is accessed to the intelligent power distribution system and is respectively in communication connection with the power control system and the monitoring dispatching system, and the power control system is respectively in communication connection with the bidirectional energy storage converter and the monitoring dispatching system. With the energy storage system of the power battery for the echelon utilization vehicle, the echelon utilization battery energy storage system is built by means of the power battery and is mainly used for storing energy of a valley load and supplying power to an important load during a load peak stage; and the energy storage converter in the echelon utilization battery energy storage system is used for stably switching between a voltage power off-line mode and a current source grid-connected mode, and the safe power supply of the load and the stable running of the echelon utilization battery energy storage system shall be ensured during the switching process.

Description

Technical field [0001] The invention relates to the technical field of battery reuse, in particular to an energy storage system for cascaded use of vehicle power batteries. Background technique [0002] The cost of lithium-ion batteries is relatively high and the vehicle life is only 3-4 years, which brings a great burden to battery procurement and operators. The direct elimination of lithium-ion batteries causes a serious waste of resources. When the capacity of an electric vehicle battery drops to 80% of the rated capacity, it is not suitable to continue to be used. If the battery is directly eliminated, it will cause a serious waste of resources. [0003] In order to maximize the remaining value of the vehicle's power battery and prolong the service life of the power battery, the power battery eliminated by electric vehicles has the conditions to continue to be used in the energy storage system. Through the cascade utilization method, not only can the battery life be prolonged...
