Battery storage system and controlling method of the same
First Claim
1. A battery storage system, comprising:
- an energy converting unit configured to generate electrical power from natural energy;
a power converter includinga control circuit, anda circuit that is controlled by the control circuit to generate electrical power to be supplied from an output of the energy converting unit to a load and electrical power to be supplied to the control circuit;
a power supply source including a battery storage cell and a commercial power system; and
a host control circuit configured to perform control such that electrical power is supplied (i) from the power supply source to the control circuit when an output of the energy converting unit is between a first value and a second value larger than the first value, and (ii) from the energy converting unit to the control circuit when the output of the energy converting unit is larger than the second value.

7. A controlling method of a battery storage system, comprising
performing control such that electrical power is supplied (i) from a power supply source including a battery storage cell and a commercial power system to a control circuit of a power converter when an output of an energy converting unit configured to generate electrical power from natural energy is between a first value and a second value larger than the first value, and (ii) from the energy converting unit configured to generate electrical power from natural energy to the control circuit when the output of the energy converting unit is larger than the second value, the power converter including the control circuit and a circuit that is controlled by the control circuit to generate electrical power to be supplied from the output of the energy converting unit to a load and electrical power to be supplied to the control circuit.
