6.1.3 Prevention of vehicle battery from complete discharge (applicable to continuously recording EVDR only)
EVDRs capable of continuous recording shall be equipped with a complete discharge prevention function to protect vehicle batteries.
EVDRs with continuous recording capability are usually connected to vehicle’s battery all the time. So, these EVDRs shall be able to record the event video data even when the vehicle is in ignition condition.
Any test organization shall check whether the EVDR cuts the power off when the DC voltage of the battery reaches less than 90 % (10,8 V for 12 V or 21,6 V for 24 V). If an effective discharge prevention technology other than detection of voltage drop has been applied and verified by relevant testing organizations, the test described below can be skipped.
a) Input voltages of 10,4 V and 10,0 V shall each be applied twice for the 12 V EVDR system (20,8 V and 20 V shall be applied for 24 V system).
b) After 1 mm, check if the power consumption by the EVDR has been stopped. At this point, the leakage current shall be less than 10 mA. After the test, the EVDR shall function normally.
6.1.4 Tests on conducted emission, radiated emission, and radiated immunity
Tests on conducted emission, radiated emission, and radiated immunity shall comply with the
radio waves act (electromagnetic compatibility) of each country.
6.2 Vehicle dynamics data and other performance
The EVDR shall be checked to verify that it satisfies the performance indicators described in
6.2 of IEC 63005-1:2017.
a) Audio shall remain unrecorded even if the EVDR has an audio recording function that can be disabled.
b) Using the acceleration-generating equipment, apply the acceleration described in 5.2.4 on the EVDR under test three times to simulate multiple collision events. The interval between acceleration application shall be greater than 10 mm.
c) Using the acceleration-generating equipment, apply the acceleration described in 5.3 on the EVDR under test two times to simulate multiple collision events. The interval between acceleration application shall be greater than 10 mm.
d) The maximum value of vector sum of recorded acceleration data a and shall be within the range of 1,2 g to 1,8 g. The EVDR under test shall meet this criterion at least one time
out of 2 attempts.
e) The EVDR under test shall be checked to verify if all the mandatory event data have been properly stored.
1) The output values through the suggested interface of the EVDR products shall include time when event data was recorded, front camera image, acceleration a, and acceleration a. The recorded data including video, acceleration a and acceleration shall be verified through a dedicated software program suggested by the manufacturer. The means for verifying recorded data shall be described in the product manual.
2) The stored event video data shall be checked to verify that it contains 3 sets of recorded event data.
3) Recorded event video data shall be inspected if proper time synchronization among them is possible.
4) The sampling frequency of a and a to be recorded shall be greater or equal to 20 Hz.
5) The resolution of recorded a and ay shall be less than or equal to 0,01 g.EN IEC 63005-2 pdf download.
