EV.7.7 Brake System Plausibility Device - BSPD

EV.7.7.1 The vehicle must have a standalone nonprogrammable circuit to check for simultaneous
braking and high power output
The BSPD must be provided in addition to the APPS / Brake Pedal Plausibility Check (EV.4.7)

EV.7.7.2 The BSPD must Open the Shutdown Circuit EV.7.2.2 when the two of these exist:

• Demand for Hard Braking EV.4.6
• Tractive System current is at a level where 5 kW of electrical power in the DC circuit is
  delivered to the Motor(s) at the nominal battery voltage
  The BSPD may delay opening the shutdown circuit up to 0.5 sec to prevent false trips

EV.7.7.3 The BSPD must Open the Shutdown Circuit EV.7.2.2 when there is an open or short circuit in
any sensor input
