EV.8.7.1 The vehicle must have a standalone nonprogrammable circuit to check for simultaneous braking and high power output
EV.8.7.2 The BSPD must be provided in addition to the APPS / Brake Pedal Plausibility Check (EV.5.7) EV.8.7.3 The BSPD must Open the Shutdown Circuit EV.8.2.2 when all three of the following exist:
Braking hard without locking the wheels
Motor/Accumulator current is at a level where 5 kW of electrical power in the DC circuit is delivered to the Motors at the nominal battery voltage.
The implausibility is persistent for more than 0.5 sec
EV.8.7.4 The BSPD must Open the Shutdown Circuit EV.8.2.2 when there is an open or short circuit in any sensor input
EV.8.7.5 The team must have a test to demonstrate BSPD operation at Electrical Technical Inspection.
a. Power must not be sent to the Motor(s) of the vehicle during the test
b. The test must prove the function of the complete BSPD, including the current sensor
The suggested test would introduce a current by a separate wire from an external power supply simulating the Tractive System current while pressing the brake pedal
