摘要:
A charge/discharge condition adoptable in a secondary battery of high-temperature operation type is calculated by a small amount of calculations. A resource matrix includes a plurality of state indicators, and includes a charge/discharge condition corresponding to each of the plurality of state indicators, to thereby include a plurality of charge/discharge conditions. The resource matrix is referred to and two or more state indicators related to an input state indicator so as to satisfy a condition are selected from the plurality of state indicators. A charge/discharge condition corresponding to each of the two or more selected state indicators are extracted from the plurality of charge/discharge conditions, so that two or more charge/discharge conditions are extracted. Interpolation is performed in the two or more selected state indicators and the two or more extracted charge/discharge conditions, so that a charge/discharge condition adoptable in a secondary battery in a case where a state of the secondary battery is indicated by the input state indicator, is calculated.

The present invention discloses a lithium-ion battery protector, comprising a broken-circuit protection switch arranged in a charging loop of a lithium-ion battery pack, wherein the broken-circuit protection switch is adapted to carry out the switching-on or switching-off of the charging loop of the lithium-ion battery pack via the shape change of a shape memory alloy therein at different temperatures. The lithium-ion battery protector uses the memorability, interference resistance, high voltage resistance and passive over-current capacity of the shape memory alloy. The complex protection system of a lithium-ion battery is simplified, the battery is modularized, the existing defects of short service life, poor stability, weak interference resistance, weak high voltage resistance, poor over-current capacity and the like of an electronic semiconductor switch (e.g. MOSFET) are overcome, and the problem of safety of the lithium-ion battery is effectively solved. Since the physical characteristics of switch materials are used, the functions of battery core balance and over-charging suppression are taken into account while a switch is triggered by a temperature signal. It is guaranteed that the battery module can carry out the expectable random series-parallel connection usage, thereby reducing the usage threshold of the lithium power battery.

A grid-connected power supply system includes a power generation apparatus configured to generate power by using natural energy and connected in parallel to a commercial power grid; a electricity storage device; and a control device configured. The control device predicts an amount of power to be generated on a subsequent day by the power generation apparatus and a power demand of the loads and charges the electricity storage device with power in a time zone in which an electricity rate of the commercial power grid is relatively low if a predicted value of the amount of power to be generated is lower than a predicted value of the power demand, or does not charge the electricity storage device with power during the time zone if the predicted value of the amount of power to be generated is not lower than the predicted value of the power demand.
摘要:
A power supply system includes a main power storage device (BA) and a plurality of sub power storage devices (BB1, BB2). A converter (12B) is sequentially connected to one of the sub power storage devices (BB1, BB2) to convert voltage between the selected sub power storage device and an electric power feeding line (PL2) bidirectionally. The sub power storage device undergoes a connection switching process, and when there is no new sub power storage device remaining for replacement, then, in accordance with that sub power storage device's SOC and the vehicle's state, a request is generated to disconnect the sub power storage device. Here, when a condition regarding a temperature of at least one of the main power storage device and the plurality of sub power storage devices is satisfied, generation of a disconnection request is prohibited, in order to protect the main power storage device.
