When measuring, power storage battery and auxiliary storage battery shall be disconnected; the bonding parts of auxiliary circuit at both ends shall be connected with vehicle chassis. 6.2.2.3 Under maximum operating voltage, the minimum value of insulation resistance for DC circuit shall be at least greater than100 Ω/V; for AC circuit, it shall be at least greater than 500 Ω/V. 6.3 Drive capability 6.3.1 Driving wheel driving force under specified operating conditions It shall be tested for driving wheel driving force under specified operating conditions according to the following methods. a) Place driving wheel of vehicles-under-test on chassis dynamometer roller. Dynamometer uses constant-speed control mode; b) Start vehicle and accelerate gradually. Electric vehicles with transmission change to direct gear; c) The measurement speed of category-M1 and category-N1 vehicles is (60±0.2) km/h through dynamometer control system; except category-M1 and category-N1 vehicles, the measurement speed of other vehicles is (50±0.2) km/h; d) Step on accelerator pedal slowly, step by step, until the displayed driving force is higher than the calculated value of loading force specified in 6.3.3, stabilizing for more than 10 s. Record power, torsion and speed of vehicles-under-test within measurement interval stabilizing for 10 s and take average value; e) If accelerator pedal is maximally depressed, the displayed driving force still cannot reach the calculated value of loading force specified in 6.3.3; then record the power, torsion and speed of vehicles within 10 s measurement-interval; and take the average value; label it with obvious mark, then exit this test. 6.3.2 Stable running capacity under specified operating conditions storage battery management system does not meet the needs of power storage battery of QC/T 897, then use testing equipment to measure directly the total voltage, total current and temperature of power storage battery system; b) Before the beginning of the test, record the monomer voltage of power storage battery Ui, the total voltage of power storage battery system Ut, the nominal total voltage of manufacturer’s power storage battery system Utn, and the standard discharge current of manufacturer’s power storage battery system It; c) According to the method of "6.4.1b)", load chassis dynamometer, set and control testing vehicle speed of vehicles-under-test; d) After the vehicle speed is stable for 5 seconds, measure the steady current value I't of power storage battery system under steady speed, continuously sampling 3 times; interval time is no less than 2 s, record average value; e) After the end of the test, record the average value of total voltage of power storage battery system-U't, battery monomer voltage - U'i, i = 1, 2, ... n within 2 s; record the maximum value of all temperature measurement points of battery system within 2 seconds after the end of vehicle driving- Tmax; f) When the battery temperature exceeds 65 °C, stop testing; When the battery system automatically terminates discharge, stop testing; In discharge stage, if the monomer storage battery voltage is lower than the final discharging voltage specified in technical conditions of the enterprises, then stop testing; when the SOC (battery state of charge) is lower than 30%, then stop testing, record the monomer voltage for SOC at 30%; When the running speed of vehicles cannot reach 54 km/h (category-M1 and category-N1 vehicles) or 45 km/h (other in-use electric vehicles except category-M1 and category-N1 vehicles), stop testing. 6.5.2 Technical indicators of power storage battery system 6.5.2.1 Maximum voltage difference of power storage battery module under specified conditions - ΔUs After testing in accordance with the method of 6.5.1, within 2s, collect respectively each monomer voltage in series in power storage battery module; the maximum voltage difference of battery monomer of power storage battery module is calculated according to equation (3). Collect the maximum value, Tmax, in degrees Celsius (°C), of all temperature measurement points of power storage battery system for vehicles within 2s after the end of the test, in accordance with the method of 6.5.1. 6.5.2.5 Power storage battery capacity Power storage battery capacity is tested according to the following methods. a) According to the discharge procedure of power storage battery specified in GB/T 18386, the power storage battery of vehicles-under-test is fully discharged until the battery system automatically terminates discharging; b) The power storage battery that is completely discharged for vehicles- under-test stands for 20min ~ 30min; c) According to the charging process of GB/T 18385, use charge-discharge machine to charge for power storage battery, so that the power storage battery is fully charged; d) Record the capacity of fully-charged battery as the actual capacity of the power storage battery. 6.6 In-vehicle electromagnetic environment The testing points of in-vehicle electromagnetic environment shall select 3 points among the following 5 points -- including the front center of driver's seat, in the middle of co-pilot's two feet, in the middle of back-row seat near rear axle, in the middle of last-row seat, and the in-vehicle position closest to motor controller; the selected 3 points shall be tested according to the following methods. a) Before starting vehicle, turn on electromagnetic radiation test-meter; measure and record the electric field intensity and magnetic induction intensity that are measured at a given position in the vehicle; b) According to the method of "6.4.1b)", load chassis dynamometer; set and control the testing vehicle speed of vehicles-under-test; c) After the speed is stable, turn on electromagnetic radiation test-meter; measure and record the data of electric field intensity and magnetic induction intensity that are measured at a given position in the vehicle.
