Abstract: A method and apparatus of detecting the states of a battery involve passing test-oriented charging and discharging pulse pair to a battery under test, and retrieving parameters of the battery, such as voltage, current, and temperature, which respond to the charging and discharging pulse pair, so as to estimate the battery states. The battery states include information pertaining to open-circuit voltage, internal resistance, capacitance, state of charge, and state of health of the battery. The battery state-related information is conducive to quick battery state detection and grading.

Abstract: A household energy management and dispatching system includes: a power generation device, converters, an energy storage device, an energy management controller, local servers and a cloud server. Each of the converters is electrically connected to the power generation device, an electricity grid, the energy storage device and the energy management controller, configured to receive a power generation electrical energy or a utility power, and transmitted to the energy storage device and a load. Each of the local servers is electrically connected to each of the converters and configured to read an electrical energy information, a utility power information and an energy storage information. The cloud server is electrically connected to the local servers. The local servers perform an edge computing analysis to obtain an edge information according to the above information. The system is used to provide a buffer to stabilize the grid and power dispatching.

Abstract: A control method for using a battery for energy storage for contract capacity users includes, turning on a demand controller, starting output power calculation and battery power supply control, measuring a power consumption time interval set by a utility company as a cycle time, obtaining a power value that a load can use every minute, measuring and calculating an output power of a utility power output once a minute, and accumulating the output power according to time and comparing it with an accumulative usable contract capacity. When accumulative output power of the utility power output is greater than accumulative usable contract capacity and voltage of the battery is higher than a preset lower limit, start the battery to supply power to the load and when the voltage of the battery is lower than the preset lower limit, the battery will not supply power to the load.

Abstract: A system with multiple functions of energy storage, Internet of things (IoT) and disaster communication is disclosed. The system includes an energy management controller connected to a power input, a digital meter, an energy storage battery pack, a power inverter, an automatic transfer switch system and a communication device with IoT and wireless communication function, and is used to control the energy storage battery pack into a charge/discharge mode or a protection mode according to a charge/discharge algorithm for the energy storage battery pack and to receive frequency conversion, voice or text messages from the communication device with IoT and wireless communication function. The energy management controller also controls the automatic transfer switch system to enable an emergency power supply control procedure when a utility power grid tripping occurs during a typhoon, an earthquake or any other emergency condition. A control method of the system is also disclosed.
