Electric energy routing system based on battery residual SOC state

Abstract

The invention discloses an electric energy routing system based on a battery residual SOC (state of charge) state, which comprises four BUCK-BOOST electric energy conversion units, a DC / AC bidirectional conversion unit, a core processing unit, a sampling circuit and a main circuit, and is characterized in that a power supply is connected to a battery through judging the battery residual SOC, the current power to-be-supplemented amount and the maximum release power of each battery module; power distribution is carried out by judging factors such as actual working conditions, the service life of a battery and the stability of a system are guaranteed, and if photovoltaic power is connected, control is carried out through MPPT, and direct-current voltage-stabilized source connection is defaulted. An integrated chip is adopted for voltage and current acquisition and various driving control structurally, so that the functional integrity of the whole system is ensured, and the structure of the system is simplified. The whole system has the advantages of being long in service life, simple in structure, portable and stable in control.
