Figure 1 Overview of relevant European Standards applying to leisure accommodation vehicles BS EN 1648-1:2012EN 1648-1:2012 (E) 7 1 Scope This European Standard specifies safety, health and functional requirements
29、 for 12 V direct current (DC) extra low voltage (ELV) electrical installations for habitation aspects of caravans. It covers the design and integration of the caravan system with the towing vehicle system. It does not apply to commercial trailers; nor does it include requirements for ELV road lighti
30、ng and signalling lamps and their installations, except for safety requirements for the routing of cables in LPG storage compartments. This European Standard also specifies the ELV output requirements of low voltage (LV) equipment that may be used to provide an ELV supply but it does not specify saf
31、ety, technical and functional requirements for LV appliances and installations. Requirements for LV installations are specified in HD 60364-7-721. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicatio

BS EN 1648-1:2012EN 1648-1:2012 (E) 8 4 Power supply 4.1 General The power supply shall be a nominal DC 12 V (min
39、imum 11 V and maximum 15 V). NOTE A power supply with a nominal voltage different than DC 12 V is not allowed. 4.2 Sources of supply The supply shall be obtained from one or more of the following sources: a) the electrical installation of the towing vehicle; b) an auxiliary battery mounted within th
40、e caravan (see 4.3); c) LV supply via an on-board mounted AC/DC converter (e.g. transformer, switching power supply) that complies with the requirements of the relevant standards in accordance with directive 2006/95/EC and subsequent amendments; d) DC generator (see 4.4.1); e) regenerative energy so
41、urces (see 4.4.2). If several sources of supply are used it shall be ensured that there is no unfavourable interaction. 4.3 Auxiliary batteries 4.3.1 Type of battery An auxiliary battery shall be of the rechargeable type. Non-rechargeable batteries are not auxiliary batteries according to 4.3. They
42、may be used however, provided that they are used in circuits separated from other sources of electrical supply. 4.3.2 Terminals Auxiliary battery terminals shall be clearly and durably marked “+” and “. Connections to auxiliary battery terminals shall be securely clamped or bolted to ensure continuo
43、us contact and shall be insulated unless the auxiliary battery is provided with an insulating cover. 4.3.3 Location An auxiliary battery shall be placed in a compartment according to 4.3.4, which is designed to protect it from mechanical damage, with easy access for maintenance or removal and secure
44、d to prevent movement of the battery, e.g. when the caravan is in motion. 4.3.4 Auxiliary battery compartment An acid resistant liquid tight tray shall be installed under an auxiliary battery whose electrolyte is liquid capable of holding at least 20 % of the electrolyte capacity of the recommended
45、battery, when in place. The interior of an auxiliary battery compartment shall be ventilated and protected against the corrosive effect of acid-laden gases, either by a) installing a sealed auxiliary battery that incorporates an external ventilating kit that is taken to the exterior of the caravan;
46、or BS EN 1648-1:2012EN 1648-1:2012 (E) 9 b) installing an auxiliary battery in an enclosed battery compartment that is protected internally against corrosion and is ventilated directly to the exterior of the caravan by means of a suitable tube in accordance with the battery manufacturers instruction
47、s or as supplied by the manufacturer of the auxiliary battery; or c) ventilating the compartment at both low-level and high-level to the exterior of the caravan. The construction of the interior of the compartment shall have gas tight joints and seams, including the sides of the ventilator openings,
48、 be of acid-resistant material or have an anti-corrosive finish. The minimum size of ventilation shall be not less than 80 mm2at low level and not less than 80 mm2at high level. If the compartment opens into the interior of the caravan, the lid shall provide an air seal. The requirements concerning
49、the protection against corrosion and ventilation are not applicable if batteries with bound electrolytes are used. If an auxiliary battery is not provided, then the position and instructions for the installation of the battery and compartment, in accordance with a), b) or c), shall be included in the Users Handbook according to Clause 8 and a notice shall be fixed in or near the proposed location sta
