It applies only to installations which are electrica

32、lly connected with the electrical installation of the base vehicle or which can be electrically connected with it by means of change-over devices. 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

33、 specify safety, 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 are referred to in the text in such a way that some or all of their content constitutes requir

39、2018EN 1648-2:2018 (E) 7 4 Power supply 4.1 General The power supply shall be a nominal DC 12 V (minimum 11 V and maximum 15 V) obtained from an auxiliary battery, except in the case of a motor caravan where the overall plan area does not exceed 8,5 m2plan area. In this case, it is permissible to us

40、e only the base vehicle battery. Where the base vehicle battery/batteries is/are operating at DC 12 V, connection to the habitation ELV electrical system shall only be made at DC 12 V. 4.2 Sources of supply The supply of the auxiliary battery shall be obtained from the electrical installation of the

41、 base vehicle or from one or more of the following sources: a) battery charger (see 7.4); Where the charger is combined with an AC/DC converter (see d) and 4.4.1) fixed within the motor caravan, then individual items of current using equipment can also be supplied with electricity directly from this

42、 AC/DC converter. b) generator that is driven by any form of energy (see 4.4); c) solar energy cells (see 4.4); d) 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 2

43、014/35/EU and subsequent amendments. It shall be ensured that the auxiliary battery will be automatically disconnected from the power supply of the base vehicle when the engine of the base vehicle is turned off. If several sources of supply are used it shall be ensured that there is no unfavourable

44、interaction. 4.3 Auxiliary batteries 4.3.1 Type of battery An auxiliary battery shall be of the rechargeable type. An auxiliary battery shall only be intended for the electric power supply of the habitation area. 4.3.2 Capacity An auxiliary battery shall have a minimum capacity of at least 60 Ampere

45、-hours (Ah) at 20 h discharge rate. It is recommended to use a battery designed to be discharged over long periods at a relatively low current. 4.3.3 Terminals Auxiliary battery terminals shall be clearly and durably marked “+” and “. Connections to auxiliary battery terminals shall be securely clam

46、ped or bolted to ensure continuous contact and shall be insulated unless the auxiliary battery is provided with an insulating cover. BS EN 1648-2:2018EN 1648-2:2018 (E) 8 4.3.4 Location If an auxiliary battery is not installed in the engine compartment, it shall be placed in a compartment according

47、to 4.3.6, which is designed to protect it from mechanical damage, with easy access for maintenance and/or removal and secured to prevent movement of the battery, e.g. when the motor caravan is in motion. 4.3.5 Motor caravans without auxiliary battery For motor caravans over 8,5 m2where an auxiliary

48、battery is intended to be used but not provided, then the position and instructions for the installation shall be included in the users handbook according to Clause 8 and a notice shall be fixed in its compartment or near the proposed location. If a motor caravan is not designed to accept an auxilia

49、ry battery, it shall be clearly stated in the users handbook. 4.3.6 Auxiliary battery compartment 4.3.6.1 General The users 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. 4.3.6.2 Resistant tray Under an auxiliary battery whose electrolyte can flow, an electrolyte resistant tray shall be installed, capable of holding at least 20 % of the electrolyte capacity of the recommen
