24、ehicles in order that they remain safe both for the users of the vehicle and for the environment of the vehicle (pedestrian, protection of nature against pollution etc.). This standard does not apply to maintenance operations and specific requirements for vehicles connected to an external power supp
25、ly. This Part deals with specific requirements related to the on board electrochemical storage of energy. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at appropriate places in the t

29、wing definitions apply. 3.1 cell A cell is an electrochemical energy storage device, of which the nominal voltage is the electrochemical couple nominal voltage, made of positive and negative electrodes, and an electrolyte. 3.2 battery module A battery module is a single unit containing one cell or a
30、 set of cells electrically connected and mechanically assembled. 3.3 battery pack A battery pack is a single mechanical assembly comprising battery modules, retaining frames or trays. The battery pack can include other components, for example topping-up and temperature control. 3.4 battery (traction
31、 battery) A battery is the collection of all battery packs which are electrically connected, for the supply of energy to the power circuit. 3.5 exposed conductive part In accordance with International Electrotechnical Vocabulary (IEV), an exposed conductive part is a conductive part which can readil
32、y be touched, and which is not electrically energized in normal use, but which can become energized under fault conditions (insulation failure). For this standard, readily be touched means can be touched with a test finger IPXXB as defined in EN 60529 : 1991. NOTE. This concept is relative to a spec
33、ific electrical circuit. A live part in one circuit can be an exposed conductive part to another, e.g. a car body can be a live part of the auxiliary network but an exposed conductive part to the power circuit 3.6 live part A live part is any conductor or conductive part intended to be electrically
34、energized in normal use. 3.7 electrical chassis An electrical chassis is a set made of conductive parts electrically linked together, and all other conductive parts electrically linked to them, whose potential is taken as reference. 3.8 direct contact Direct contact is contact of persons or livestoc
35、k with live parts. 3.9 power circuit The power circuit comprises all the power equipment such as traction battery, converter (inverter, chopper, etc.), traction motor and cables and connectors, used for the propulsion of the electric vehicle and other equipment (d.c./d.c. converter, step-up, etc.) g
36、alvanically connected with this power equipment. 3.10 drive system The drive system includes all electric traction motors and the power control units for these motors; not the on board electric power source, e.g. the traction battery, not the auxiliary electronic devices, and not converters, e.g. d.
37、c./d.c. converter, on board charger (unless it is common with the inverter motor controller). 3.11 connection terminal A connection terminal is a live part of a battery module outside the enclosure of the battery module, intended to transmit electrical energy. 4 Marking 4.1 Battery pack Nearby the b
38、attery pack shall appear the symbol given in figure 1. This warning shall be unalterable and very visible if someone tries to access the battery. 4.2 Battery type The chemical type of battery shall be clearly and visibly indicated for the benefit of emergency and rescue people.

Figure 1. 5 Exhaust gas from battery The vehicle
40、 manufacturer shall state the maximum flow rate (in cubic metres per hour) and the maximum volume (in cubic metres) in the two following situations: in case of normal service; and in case of a first failure of devices involved in the charging process. NOTE. These two values can be used to determine
41、the ventilation device in the charging room. 6 Installation rules of the battery 6.1 Protection against direct contact Protection against direct contacts shall conform to clause 5 of prEN 1987-3 : 1996. 6.2 Insulation resistance of the battery 6.2.1 Test method Considering the requirements and the m
42、easuring devices used, this test is not applicable for insulation resistances of the battery higher than 1 MV. If the battery has a galvanic link to the electrical chassis of the vehicle, the insulation resistance values and the measurement method are still valid. To do the measurement, it is only n
43、ecessary to disconnect the battery from the electrical chassis of the vehicle. Throughout the test, the battery shall have an open circuit voltage greater than its nominal value. The two poles of the battery shall be disconnected from the power circuit. The voltmeter used in this test shall measure
44、d.c. values and have an internal resistance greater than 10 MV. Measurement shall be made in three steps: a) step one: Measure U1in accordance with the test assembly in figure 2. 1 traction battery 2 electrical chassis Figure 2.

49、a new battery the insulation resistance Rishall be greater than (500 3 U) V, where U is the nominal voltage of the battery. This value shall stay higher than (100 3 U) V within its lifetime. 6.3 Creepage distance This subclause deals with additional leakage current hazards between the connection terminal of a battery module including any conductive fittings attached to them and any exposed conductive parts, due to the risk of electrolyte spillage or leakage. It does not apply to fully sealed batteries, for which t
