Introduction This introduction is not part of IEEE Std 1661-2007, IEEE Guide for Test and Evaluation of Lead-Acid Batteries Used in Photovoltaic
8、(PV) Hybrid Power Systems. The hybrid power system in this guide refers to a photovoltaic (PV) energy charging source and a dispatchable charging source, such as an engine generator. The hybrid power system designer depends on the capacity of storage batteries for reliable extended operation of the
9、system load to more effectively utilize and store the PV energy and minimize engine generator run-time. PV hybrid systems, which are the most common hybrid systems, can subject batteries to harsh operational environments as a result of insufficient charging, continuous cycling, and temperature extre
10、mes. Typical charge rates for PV hybrid systems can range from very low rates near the 100 h rate to high rates near the 6 h rate. The effect on the battery can be significant with respect to heat generation and charge control parameters. In daily operation, the limited available PV and engine gener
11、ator charging sources combined with relatively low charge regulation voltages may be insufficient to provide a full charge to the battery. In an effort to identify appropriate PV hybrid system parameters together with appropriate battery technology, a repeatable test procedure is provided to verify
12、PV hybrid system battery performance based on a field test. The recommended test plan for evaluating PV batteries includes the following: Limitations and expectations System parameter selection PV hybrid battery capacity test Interpretation of test results This guide may be used separately, or in co

The Authoritative Dictionary of IEEE Standards Terms B33should be referenced for terms not defined in this clause. 3.1 boost charge: A battery charge to recover lost capa
39、city from an extended period of non-use or cycling. 3.2 charge controller: An electrical control device that regulates battery charging by voltage control and/or other means. The charge controller may also incorporate one or more of the following functions: discharge termination, regulation voltage
40、temperature compensation, load control, data acquisition, and status indication. 3.3 dispatchable power source: An electrical power generator that is available on demand. 3.4 end-of-discharge voltage: The battery voltage at which the discharge test is terminated. 3.5 finish charge: The continuation
41、of a taper charge beyond the arbitrary duration of the taper charge to fully restore the battery to 100% state of charge (SOC). 3.6 hybrid power system: A hybrid power system that integrates two or more energy generation sources, a battery for energy storage, and necessary controls for the purpose o
42、f supplying electricity to loads. For the purposes of this guide, the hybrid power system includes an engine generator and a renewable power resource, such as PV. 3.7 monoblock: The smallest number of packaged cells in a battery string where the string of cell voltages can be measured. Usually cells
43、 are packaged in 6 V or 12 V monoblocks. 3.8 percent overcharge: The excess amount of energy returned to a battery, expressed as a percentage of the energy removed in the previous discharge. Typical percent overcharge values are between 105% and 130% depending on battery design. 3.9 premature capaci
