Strong GB38031 - 2020 'the electric car battery safety requirements with dynamic' battery pack or system security testing project

This article will parse the battery pack or system safety requirements in the standard test items and methods, at the same time, we were recommended for everybody jester company design and manufacture of battery pack or system security testing equipment for your reference. Battery pack or system security requirements: 1, the working status confirmation: before the official start of the test, the battery pack or system of electronic component or BCU should be in normal working condition. 2, test items and test methods: serial number test program test method (reference 1 vibration equipment and model reference pictures. Test object for the battery pack or system. 2. To protect the test operation personnel and laboratory safety, manufacturer shall provide voltage spring limits as abnormal termination conditions. 3. Before the start of the trial will test the object's state of SOC to no less than 50% of the normal SOC work scope provided by the manufacturer. 4. According to the installation position of motor vehicles and GB/T2423 test object. 43, install the test object on the vibration table. Each direction randomly and fixed frequency vibration load, load order appropriate for z axis random fixed frequency, z axis, y axis random, y axis fixed frequency, the x axis random, the x axis fixed frequency ( The car moving direction for the x axis direction, another perpendicular to the horizontal direction of the moving direction of y direction) 。 Inspection agencies also can choose order, in order to shorten the conversion time. According to the GB/T2423 test process. 56. 5. To load on the vehicle other than the M1, the N1 class battery pack or system, vibration test parameters shall be carried out in accordance with the table 2 and figure 2, for test objects, there are multiple installation direction ( x / y / z) When tested according to the installation of the RMS big direction. For the installation in the vehicle at the top of the battery pack or system, according to the manufacturers not below table 2 and figure 2 vibration test parameters of vibration test. 6. For loading in M1, N1 class vehicle battery pack or system, vibration test parameters according to table 3 and FIG. 3. 7. During the trial, monitoring test object within the minimum monitoring unit of the state, such as voltage and temperature, etc. 8. After completion of the above test steps in a test environment temperature observation HGX - 2 600 - Mechanical shock 1 ZDN electric vibration table 2. Test object for the battery pack or system. 2. The test objects in the half sine wave, given in table 4 & plusmn; Z direction each 6 times, a total of 12 times. 3. A half sine wave maximum and minimum tolerance allowed range as shown in table 5 and 4. 4. Twice the time interval between two times to impact on the test samples of response is not influence each other, generally should not be less than 5 times the impact pulse duration. 5. After completion of the above test steps in the test were observed under ambient temperature for 2 h. GX - 5099 - S20 mechanical shock test rig simulation collision 1 3. Test object for the battery pack or system. 2. According to the installation position of motor vehicles and GB/T2423 test object. 43 the requirements, the test object level with stents installed in the car. According to the regulations of the pallet test object using the environment under pulse, and fell on the table 6 and 5 minimum and maximum range of allowable tolerance ( The car moving direction for the x axis direction, another perpendicular to the horizontal direction of the moving direction of y direction) 。 For test objects, there are multiple installation direction ( x / y / z) When tested according to the installation of the high acceleration direction. 3. After completion of the above test steps in the test were observed under ambient temperature for 2 h. GX - Acceleration impact testing machine 4 extrusion 1 5099. Test object for the battery pack or system. 2. Test according to the following conditions: a) Extrusion plate form ( Choose one of the following two extrusion) :本; — Extrusion plate as shown in figure 6, the radius of 75 mm half cylinder, half the length of the cylinder ( L） Is greater than the height of the test object, but not more than 1 m; — 本
