These m
41、easures are described in detail in IEC 60364-4-41 specifying the protection against electric shock on installations up to 1 000 V a.c. or 1 500 V d.c. The following clauses describe the typical measures to be taken for traction batteries in electrical vehicles. 4.1 Protection against both direct and
42、 indirect contact Protection against direct and indirect contact is simultaneously met by the use of safety extra low voltage (SELV) (24 V d.c.) or protective extra low voltage (PELV) (24 V d.c.), as long as the whole installation corresponds to the conditions for SELV or PELV. - 7 - EN 50272-3:2002
43、 For protection against direct contact the following protective measures apply: - protection by insulation of live parts; - protection by barriers or enclosures; - protection by obstacles. (see IEC 60364-4-41,412.1 to 412.3). For protection against indirect contact the following measures can be sele
44、cted: - protection by automatic disconnection or signalling; - protection by protective insulation; - protection by earth-free local equipotential bonding; - protective electrical separation. 4.2 Protection against direct and indirect contact when discharging the traction battery on the vehicle (bat
45、tery disconnected from charger / mains) 4.2.1 Batteries with nominal voltages up to and including 60 V d.c. do not require protection against electric shock caused by direct contact, as long as the whole installation corresponds to the conditions for SELV and PELV. However, for other reasons, e.g. s
46、hort circuits, mechanical damage, all batteries in electrical vehicles require protection against direct contact of live parts, even if the battery nominal voltage is 60 V d.c. or less. 4.2.2 Batteries with nominal voltages from above 60 V d.c. and up to and including 120 V d.c. require protective m
47、easures against direct contact. NOTE Batteries with nominal voltages up to and including 120 V d.c. are regarded as safe power sources for SELV-systems (safety extra low voltage) or PELV-systems (protective extra low voltage) (see IEC 60364-4-41,411.1). The following protective measures apply: a) in
48、sulation of live parts; b) barriers or enclosures; c) obstacles or placing out of reach. If the protection against direct contact of live parts is ensured only by obstacles or placing out of reach, the battery accommodation shall have access restricted to trained and authorized personnel only, and s
49、hall be marked by warning labels Batteries having nominal voltages exceeding 120 V d.c. require protective measures against both direct and indirect contact. Battery compartments with batteries having nominal voltages exceeding 120 V d.c. shall be locked and have restricted access for trained and authorized personnel only and shall be marked by warning labels (see Clause 11). For batteries with nominal voltages exceeding 120 V d.c. the following protective measures against indirect contact can be selected: - protective electrical insulation; - protection by earth-free equip
