3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-482 and the following
apply.
3.1
stationary battery / stationary battery installation
stationary batteries are installed in a fixed location and not generally intended to be moved from place to
place. They are permanently connected to both the load and the power supply and are incorporated into
stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS),
utility switching, emergency power or similar applications
3.2
traction battery
a secondary battery which is designed to provide the propulsion energy for electrical vehicles
3.3
cranking battery
cranking batteries are used for starting of internal combustion engines in stationary, railway or other
onboard applications
3.4
starter battery
starter batteries are primarily used as a power source for the starting of internal combustion engines, lighting
and also for auxiliary equipment of internal combustion engine vehicles
3.5
onboard battery
batteries used for power supply of a DC network onboard ships, rail vehicles or off-road vehicles without
authorization for public traffic
3.6
aircraft battery
batteries used in aircrafts and helicopters for starting auxiliary engine and powering DC network
3.7
portable battery
portable batteries are mainly used for power supply of portable appliances
NOTE Batteries for portable equipment are usually maintenance-free.
3.8
battery room
room in a building dedicated for the accommodation of stationary batteries
3.9
battery enclosure
enclosure designed for the accommodation of batteries to protect against environmental impacts,
unauthorised access of persons and hazards caused by the batteries
3.9.1
battery cabinet
enclosure equipped with lockable or non-lockable doors for servicing the battery. The cabinet can be
completely or partly filled with batteries or can be equipped with additional electric or electronic devices
respectively
3.9.2
battery shelter
battery enclosure for outdoor installations. It can be designed as a movable unit for transportation
3.9.3
battery box
closed box designed for the accommodation of batteries. They can form an integral part or parts of other
equipment
3.10
mode of operation
batteries require different type of charging and discharging depending on the type of application. 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 operation (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. Battery, load and charger are permanently connected and operated in
parallel. In case of power failure the load is continuously powered without any interruption by
discharging the battery
3.11
charge of a battery
operation during which a secondary cell or battery is supplied with electric energy from an external circuit
which results in chemical changes within the cell and thus storage of energy as chemical energy
[IEV 482-05-27 MOD]
3.12
discharge of a battery
operation by which a secondary
