  • Check for any battery warning lights or error codes.
  • Verify battery cooling system operation (if equipped).
  • Inspect battery pack mounting and security bolts.
  • Check for any unusual odors from battery compartment.
  • Verify battery management system (BMS) status indicators.

Charging System and Infrastructure

  • Inspect charging port for damage, debris, or corrosion.
  • Check charging cable and connector condition.
  • Verify charging port door/cover operates properly.
  • Test charging system communication with station.
  • Check for proper charging indicator lights operation.
  • Verify charging interlock systems function correctly.
  • Inspect onboard charger ventilation and cooling.
  • Ensure charging station connection is secure and clean.

Electric Drivetrain and Motor

  • Check electric motor operation during startup sequence.
  • Verify smooth acceleration and deceleration response.
  • Test regenerative braking system functionality.
  • Inspect motor cooling system and fluid levels.
  • Check drivetrain for unusual noises or vibrations.
  • Verify transmission/reduction gearbox operation.
  • Test motor controller temperature monitoring.
  • Check for any drivetrain error codes or warnings.

High Voltage Safety Systems

  • Verify all high voltage warning labels are visible and intact.
  • Check emergency disconnect switch accessibility and function.
  • Inspect high voltage cable routing and protection.
  • Test ground fault detection system operation.
  • Verify isolation monitoring system status.
  • Check high voltage interlock loop integrity.
  • Inspect service disconnect location and labeling.
  • Verify first responder information is posted and current.

12V Systems and Auxiliary Power

  • Check 12V auxiliary battery condition and charge level.
  • Test all exterior lighting (headlights, taillights, signals).
  • Verify interior lighting and dashboard instruments.
  • Check stop arm operation and warning lights.
  • Test horn, backup alarm, and communication systems.
  • Verify wheelchair lift operation (if equipped).
  • Check DC-DC converter operation and status.
  • Test emergency lighting and evacuation systems.

HVAC and Climate Control

  • Test electric heating system operation and efficiency.
  • Verify air conditioning compressor and cooling performance.
  • Check cabin air filtration system and filter condition.
  • Test defogger and defroster system operation.
  • Verify HVAC energy consumption is within normal range.
  • Check ventilation fan operation at all speeds.
  • Test temperature control and thermostat function.
  • Verify heat pump operation (if equipped).

Braking and Safety Systems

  • Test service brake pedal feel and stopping performance.
  • Verify regenerative braking system integration.
  • Check parking brake engagement and holding capability.
  • Test anti-lock braking system (ABS) functionality.
  • Verify brake fluid level and condition (hydraulic components).
  • Check brake warning lights and indicators.
  • Test emergency brake assist systems.
  • Verify brake system energy recovery efficiency.

Student Safety and Accessibility

  • Test all emergency exits and evacuation procedures.
  • Check student seating and restraint systems.
  • Verify two-way radio and GPS tracking systems.
  • Test cameras and safety monitoring equipment.
  • Check first aid kit and emergency equipment.
  • Verify accessibility equipment for special needs students.
  • Test student crossing arm and warning systems.
  • Check mirror adjustment and visibility aids.

Tires, Suspension, and Steering

  • Check tire pressure on all wheels including spare.
  • Inspect tire tread depth and wear patterns.
  • Verify wheel torque specifications and lug nut condition.
  • Test steering response and alignment.
  • Check suspension system for proper operation.
  • Inspect air suspension components (if equipped).
  • Verify power steering system operation.
  • Check for any unusual vibrations or noises.

Post-Trip EV Specific Checks

  • Record ending state of charge and energy consumption.
  • Check for any new warning lights or error codes.
  • Verify charging connection for overnight charging.
  • Report any performance issues or unusual behavior.
  • Document range achieved and energy efficiency.
  • Check battery thermal management system status.
  • Verify all systems properly shutdown or enter sleep mode.
  • Complete digital inspection log and route report.
