Safety

Like any project involving automobiles and tools there are inherent risks. However EVs have hazards that you should be aware of. Being aware of these possible hazards will prevent damage to the vehicle and serious injury to yourself. Below are a few basic guidelines to follow.

  1. Always shut off the power when servicing the car.
  2. Dissipate the capacitors from the controller before servicing the controller or propulsion system. Even though the controller is off the capacitors may still be live. A light bulb works well as a dissipation device.
  3. When servicing the drive train always keep the drive wheels off the ground with proper jack stands.
  4. Keep loose hair, jewelery or clothing away from spinning motor shafts.
  5. Always wear proper eye protection when working with power tools and handling batteries. Deep-cycle batteries contain caustic acid which may splash or spill when they are moved or handled.
  6. Wear protective clothing when carrying or moving batteries. Acid could spill and burn a hole through any clothing it contacts.
  7. Wear steel toed boots when carrying or moving batteries. Batteries can weigh up to 80 pounds and can cause serious injury if they fall.
  8. Wear heavy gloves when moving or carrying batteries. Use protective rubber or latex gloves when checking or watering batteries.
  9. Always provide proper ventilation when charging batteries. A small spark can cause a fire if hydrogen gas accumulates in an enclosed area.
  10. Never inhale the fumes when watering the batteries.
  11. Tape the ends of wrenches when tightening battery terminals. A loose wrench can come in contact with battery terminals and cause a short.
  12. Never ground the propulsion batteries.
  13. Never work on the car when you are tired or in a hurry.
