19、1:2010 - 4 - 1 Scope This European Standard is Part 1 of EN 50272 under the generic title “Safety requirements for secondary batteries and battery installations” with nominal voltages up to DC 1 500 V (low voltage directive) and specifies the basic requirements referred to in the other parts of the
20、standard as follows: - Part 2 Stationary batteries - Part 3 Traction batteries - Part 4 Batteries for use in portable appliances The requirements regarding safety, reliability, life expectancy, mechanical strength, cycle stability, internal resistance, and battery temperature, are determined by vari
21、ous applications, and this, in turn, determines the selection of the battery design and technology. In general, the requirements and definitions are specified for lead-acid and nickel-cadmium batteries. For other battery systems, the requirements may be applied accordingly. The standard covers safet
22、y aspects taking into account hazards associated with: electricity (installation, charging, discharging, etc.); electrolyte; inflammable gas mixtures; storage and transportation. With respect to electrical safety, reference is made to EN 60364-4-41. 2 Normative references The following referenced do

The following modes of operation are typical: battery / cycle operation (charge / discharge operation) The load is powered by the battery only, after the battery has been charged. This can be permanently repeated (cycle operation); response mode op
36、eration (switch mode operation) In case of power failure the load is switched to the fully charged battery. The battery is charged by a separate charger; parallel operation mode.
