17、n This standard gives information about the safety and health protection of persons when applying secondary batteries, which are used for DC power supply systems in portable appliances. Therefore the standard applies for commercially available secondary batteries and battery systems according to the
18、 requirements of the “Low Voltage Directive”. In the European countries similar relevant standards or specifications or parts of it exist, which shall be taken into account and will be replaced by this new standard. In certain portable appliances or toys the discharge of both primary and secondary c
19、ells or batteries is possible. In case of interchange ability of these cells or batteries the standards for primary batteries of the EN 60086 series, Parts 1 to 5, shall have preference. 1 Scope This standard applies to the safety aspects associated with the accommodation, the arrangements of circui
20、ts and the operation of secondary cells and batteries in portable appliances. Requirements are specified which oblige the manufacturers of appliances and secondary batteries to prevent the misuse of batteries in the course of operation to provide protective measures avoiding injury to persons in cas
21、e of battery failure and to provide sufficient information to users. 2 Normative references The following referenced documents are indispensable for the application of this document.

29、s for use in portable equipment are usually maintenance-free types. For further definitions see International Electrotechnical Vocabulary IEC 60050-482 3.2 secondary cell / battery cell which is designed to be electrically recharged, basic functional unit providing a source of electrical energy by d
30、irect conversion of chemical energy, the cell (or battery) consists of an assembly of electrodes, separators, electrolyte, container and terminals IEV 482-01-03 4 Operating instructions Users of appliances shall be informed through operating instructions about the following items, with specific refe
31、rence to batteries: a) proposed or applicable battery systems and battery dimensions according to the applicable standard, b) correct insertion of batteries into the equipment in terms of polarity, c) charging instructions for secondary batteries, d) prohibition of charging when using primary batter
32、ies, e) storage and temperature conditions, f) maintenance instructions, g) instructions for the prevention of hazard and measures to be taken following an accident, h) instructions about disposal. Operating instructions for batteries in portable appliances must be provided and can be part of the eq
33、uipment instructions. Required information for safe operation, like polarity, voltage, battery type, etc shall be repeated inside or close to the battery compartment. EN 50272-4:2007 - 6 - 5 Dimensions and interchange ability of cells and batteries Cells and batteries with reverse polarity but ident
34、ical dimensions shall not be sent into the retail market. Compliance with the existing standards is required. Interchange ability of cells and batteries with the same nominal voltage and identical dimensions, but of different technologies is permitted, if stated by the appliance manufacturer (see EN
35、 60086-1, Subclause 4.1.7). Cells in a battery string shall be of identical design, type and brand. It is recommended to use cells of same state of charge and same age (see IEC/TR 62188, Subclause 7.9). 6 Electrical safety 6.1 Protection against incorrect connection polarity Manufacturers of applian
36、ces shall provide measures against incorrect polarity connections of the battery to the device. Measures can be, e.g. marking of the position of individual cells or batteries, polarity marked cables, plugs, design of compartments and contacts, electronics, (see EN 60086-5, Annex B and EN 60335-1, An
37、nex B). NOTE Where applicable the battery symbol according to IEC 60417 database shall be used. 6.2 Design of battery and battery compartments Both, the design of battery and battery compartment, shall include provisions to minimize the risk of the battery being reversed (connected the wrong way rou
38、nd) either during use or during charge. The design of terminals and the method of connecting them to the equipment or to the charger shall make wrong connection of the battery impossible (see EN 60086-5). 6.3 Compartments for consumer replaceable batteries Where battery compartments are designed for
39、 consumer replaceable batteries the requirements in EN 60086-5 apply. 7 Safe handling and protection against misuse 7.1 Charging The charging instructions which apply to the batteries and chargers shall be observed. Where replacement of batteries by the end user is foreseen, the equipment manufactur
40、er shall provide clear instructions about the replacement battery. - 7 - EN 50272-4:2007 7.2 Thermal abuse Battery systems for portable appliances shall not be overheated. Overheating due to service conditions will destroy the battery and, in individual cases, the equipment as well. Depending on the
41、 type of battery corrosive and/or toxic liquids or gases may be released. Therefore batteries shall be inserted into the appliances in such a way that their permissible temperature range is not exceeded. 7.3 Mechanical impact Batteries shall be protected from mechanical damage which may cause leakag
42、e of hazardous chemicals causing short-circuits which may result in overheating and subsequent rupturing of further cells. 7.4 Protection against pole reversal in the event of deep discharge Secondary batteries shall be charged / discharged, so that each cell gets charged or discharged to the same e
43、xtent (taps in the battery string lead to uneven discharge condition). Only cells and/or batteries of the same type and age shall be connected in series. The maximum number of cells specified by the battery manufacturer and any required protective measure for series connection shall be observed in o
44、rder to avoid pole reversal of individual cells in the event of deep discharge of the battery bank. Depending on the battery system reverse polarity can destroy the battery, damage the appliance, and expose the user to danger e.g. due to battery leakage. A low voltage protection device may be provid
45、ed for disconnection of the equipment from the load. If some cell reversal may cause damage to equipment or persons a protective device is required. 7.5 Protection against electrical overload Appliances and batteries shall be protected by short-circuit and overload protection devices, if the availab
46、le battery power may cause damage to equipment or persons. 7.6 Safe handling To achieve safe handling during transport, installation and replacement the battery terminals and the connection cables shall be designed so that short circuits are not possible. 8 Battery compartments Secondary batteries i
47、n portable appliances can be of permanently fixed installation, can be replaceable for recharging separately outside of the appliance or can be replaceable by primary batteries. In case of replaceable batteries the requirements 8.1 to 8.4 apply. Where watertight equipment is used safety precautions
48、are required to prevent or limit the generation of hydrogen. 8.1 Battery accommodation Battery enclosures for accommodation of batteries in electrical equipment shall be designed, where necessary, to be separate from the functional parts of the equipment and accessible from the outside. NOTE Cells o
49、r batteries may leak electrolyte. Both valve-regulated and gas-tight secondary batteries have a safety device (valve or vent) which release gas when activated. EN 50272-4:2007 - 8 - 8.2 Replacement battery enclosures Battery enclosures should be accessible, so that batteries can be replaced, and the enclosure and the contacts can be cleaned. 8.3 Battery contacts Contacts and dimensions shall be designed to minimize the voltage drop and to ensure current flow, e.g. resilient contacts may be provided. The contacts inside the battery compartments shall
