21、test is not applicable for insulation resistances of the battery higher than 1 Ma. If the batteqy has a galvanic link to the electrical chassi of the vehicle, the insukition resistance values and the measurement method are stili valid To do the measurement, it is oniy necessary to disconnect the bat
22、tery 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 dc. values and have an interna
23、l resistance greater than 10 Ma. Measurement shall be made in three skps: a) step one: Measure U, in accordance with the test assembly in figure 2. 1 traction battery 2 electrical chassis Figure 2.

28、dangerous quantity of gas generated by the battery is ailowed in the passenger compartment or the enclosed load space. An example of air flow calculation for hydrogen exhaust is given in annex B, together with some basic chemical mies. 6.4.2 Tests and requirements 6.4.2.1 Test and requirement for hy
29、drogen To ensure that the critical level of hydrogen inflammability has not been reached anywhere, the foilowing test has to be applied. When charging the vehicle, the hydrogen concentration shail be measured outside a volume specified by the vehicle manufacturer around every gas exhaust No ignition
30、 point shall be located inside the volume specified by the vehicle manufacturer around gas exhausts. NOTE 1. The possible ignition points are: - electrical contacts; - fuses; - contact brushes; - brake pads; - electrostatic discharge; - possible external source e.g. cigarette, lights, etc. During th
31、e test, the recorded values of hydrogen concentrations outside these specified volumes shall be: - less than 0,s % in case of a normal running of the vehicle (driving, charging, etc.) inside and outside the vehicle; - less than 3,5 % in the case of a first failure inside and outside the vehicle. NOT
32、E 2. A first failure can be: - a faiiiig ventilation device (inside the vehicle). Then, a sufficient natural venilation shall avoid a dangerous concentration of hydrogen being reached - damage of the charger. Then, either the charger is fitted with safety devices and stops, or a forced ventilation s
33、hall be provided; - release of battery connection terminal, - disconnection of a gas exhaust tubing, etc. 6.4.2.2 Tests and requirements for othm gases NOTE. Along with development of new battery technologies, tests and associated requirements will be defined in future revisions of this standard. Pa
34、ge 7 EN 1987-1 : 1997 6.6 Chemical hazards Under normal conditions, no chemical reactant shall escape -om the battery in potenWy dangerous quantity. Under abnonnal leakage of liquid, spray or vapour, consequences shall be reduced to a minimum, especiaLly in the passenger compartment 6.6 Inter-batter
35、y modules liaison “ahg into account the environment of the battery, special attention shali be called to the connection operation of inter-battery modules (tightening, sealing, etc.).The battery manufacturer shall supply al recommendations to these connection operations, to satisfy the environmental
36、 requirements of the vehicle manufacturer (vibration, mechanical shocks, thermai shocks). 7 Overcurrent battery switch 7.1 Function The over-current battery switches have an independent safety function from the other equipment of the propulsion system. They shall open the batteqy current circuit whe
37、n an overstepping of the limits of a normal runnjng occurs. These current oversteppings can have two origins: - failure in the drive system; - short-circuit of the b - the internal resistance of the battery; - the status of charge of the batteW. The characteristic operating time - shortcircuit curre
38、nt shail be chosen according to these parameters, in order to ensure the protection of the battery on one side, and of the power circuit on the other side.

39、f the battery or battery packs are not located inside the passenger compartment, the battery, or battery packs, or their components (battery modules, electrolyte) shall not penetrate inside the passenger compartment. b) If the battery or battery packs are located inside the passenger compartment, in
40、 accordance with clause 6, any movement of the battery or baery packs due to the crash shall be limited to ensure the safety of the passengers. In both cases, 6.6 shall apply 8.2 Protection of third party The battery, battery packs, or their components (battery modules, electrolyte) shall not be eje
41、cted from the vehicle. An electrolyte leakage is tolerated only under the vehicle. 8.3 Protection against short circuit In case of crash, the power circuit shall be protected against the effects of short-circuit.
