Figure 1 Overview of relevant European Standards applying t
31、o leisure accommodation vehicles BS EN 1648-1:2018EN 1648-1:2018 (E) 6 1 Scope This European Standard specifies safety, health and functional requirements for 12 V direct current (DC) extra low voltage (ELV) electrical installations for habitation aspects of caravans. It covers the design and integr
32、ation of the caravan system with the towing vehicle system. It does not apply to commercial trailers; nor does it include requirements for ELV road lighting and signalling lamps and their installations, except for safety requirements for the routing of cables in LPG storage compartments. This Europe
33、an 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 safety, technical and functional requirements for LV appliances and installations. Requirements for LV installations are specified in HD 60364-7-721.

41、ximum 15 V). 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 the caravan (see 4.3); c) LV supply via an on-board mounted AC/DC converter (e.g. transformer, switc
42、hing power supply) that complies with the requirements of the relevant standards in accordance with Directive 2014/35/EU and subsequent amendments; d) DC generator (see 4.4.1); e) regenerative energy sources (see 4.4.2). If several sources of supply are used it shall be ensured that there is no unfa
43、vourable interaction. 4.3 Auxiliary batteries 4.3.1 Type of battery An auxiliary battery shall be of the rechargeable type. 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 ens
44、ure continuous 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 4.3.5, which is designed to protect it from mechanical damage, with easy access for maintenance and/or re
45、moval and secured to prevent movement of the battery, e.g. when the caravan is in motion. 4.3.4 Caravans without auxiliary battery If an auxiliary battery is intended to be used but not provided, then the position and instructions for the installation shall be included in the users handbook accordin
46、g to Clause 8 and a notice shall be fixed in its compartment or near the proposed location. If a caravan is not designed to accept an auxiliary battery, it shall be clearly stated in the users handbook.

47、rs handbook shall include instructions on auxiliary battery installation, when necessary. For underslung battery, a minimum ground clearance shall be observed: see Directive 2007/46/EC, Annex II. 4.3.5.2 Resistant tray Under an auxiliary battery whose electrolyte can flow, an electrolyte resistant t
48、ray shall be installed, capable of holding at least 20 % of the electrolyte capacity of the recommended battery, when in place. 4.3.5.3 Ventilation Except for sealed auxiliary battery that incorporates an external ventilating kit that is taken to the exterior of the caravan, or battery whose electro
49、lyte cannot flow in case of malfunction, the interior of an auxiliary battery compartment shall be ventilated and protected against the corrosive effect of acid-laden gases, by ventilating the compartment at both low-level and high-level to the exterior of the caravan. The construction of the compartment shall have gas tight joints and shall be sealed to prevent ingress into the habitable compartment and be of an electrolyte resistant material of the installed battery or have an anti-corrosive finish.
