Battery charge controllers for photovoltaic systems - Performance and functioning
IEC 62509:2010 establishes minimum requirements for the functioning and performance of battery charge controllers (BCC) used with lead acid batteries in terrestrial photovoltaic systems. The main aims are to ensure BCC reliability and to maximise the life of the battery. This standard shall be used in conjunction with IEC 62093.

Contrôleurs de charge de batteries pour systèmes photovoltaïques - Performance et fonctionnement
La CEI 62509:2010 spécifie les exigences minimales pour le fonctionnement et la performance des contrôleurs de charge de batterie (BCC - Battery Charge Controller) utilisés dans les batteries au plomb de systèmes photovoltaïques terrestres. Les principaux objectifs sont d'assurer la fiabilité des BCC et de maximaliser la durée de vie de la batterie. La présente Norme doit être utilisée conjointement avec la CEI 62093.
Lastnosti in delovanje fotonapetostnih krmilnikov za polnjenje baterij (IEC 62509:2010)
Ta mednarodni standard vzpostavlja minimalne zahteve za delovanje in zmogljivost krmilnikov za polnjenje baterij (BCC), ki se uporabljajo s svinčevo-kislinskimi baterijami v zemeljskih fotonapetostnih sistemih. Glavna cilja sta zagotoviti zanesljivost BCC in čim bolj podaljšati življenjsko dobo baterij. Ta standard se uporablja v povezavi z IEC 62093, ki opisuje preskus in zahteve za predvideno namestitveno aplikacijo. Poleg funkcij krmiljenja polnjenja baterij ta standard obravnava naslednje lastnosti krmiljenja polnjenja baterij: fotonapetostno generatorsko polnjenje baterij, nadzor obremenitve, zaščitne funkcije, vmesniške funkcije. Ta standard ne zajema zmogljivosti MPPT, vendar velja za enote BCC, ki imajo to funkcijo. Ta standard opredeljuje zahteve za delovanje in zmogljivost za krmilnike za polnjenje baterij ter navaja preskuse za ugotavljanje karakteristik delovanja in zmogljivosti krmilnikov polnjenja. Velja, da se IEC 62093 uporablja za ugotavljanje konstrukcijskih zahtev za predvideno namestitev, ki med drugim vključuje vidike, kot so ohišje, čvrstost fizične povezave in varnost. Ta standard je napisan za aplikacije svinčevo-kislinskih baterij. Ni omejen glede na zmogljivosti BCC, do katere bi se lahko uporabil, vendar pa so zahteve za preskusno opremo pri uporabi na BCC z visoko napetostjo ali tokom, na primer višjih od 120 V oziroma 100 A, težko dosegljive. Ti pristopi lahko veljajo tudi za druge vire napajanja in druge tehnologije baterij, na primer baterije Ni-Cd, z uporabo ustreznih vrednosti napetosti galvanskega člena.

BATTERY CHARGE CONTROLLERS FOR PHOTOVOLTAIC SYSTEMS –
PERFORMANCE AND FUNCTIONING
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identi
