Leisure accommodation vehicles - 12 V direct current extra low voltage electrical installations - Part 2: Motor caravans
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 motor caravans.
It applies only to installations which are electrically 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 specify safety, technical and functional requirements for LV appliances and installations. Requirements for LV installations are specified in HD 60364-7-721.

EN 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 m2 plan area. In this case, it is permissible to use 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 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 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 2014/35/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 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-hours (Ah) at 20 h discharge rate. It is recommended to use a battery designed to be discharged over
