What safety precautions should be taken when working on a hybrid electric vehicle?
Maintain a “safety zone” around their work, including using yellow caution tape and “DO NOT TOUCH “HIGH-VOLTAGE” signs when high-voltage system repairs are to be left unattended. 1. Do NOT touch ANY high-voltage wiring, connectors, or parts, such as the inverter or the hybrid battery assembly. 2.
What should be removed when working on a hybrid vehicle?
After verifying that the vehicle’s ignition key has been removed, its keyless start function (if equipped) disabled, and its 12V battery disconnected, you will typically put on a pair of rubber insulating gloves, then disconnect the vehicle’s HV system by either removing a service plug or turning a safety switch to OFF …
Is it safe to work on hybrid cars?
The most serious safety concern when working on hybrid vehicles is, of course, the high-voltage electrical system, which includes the motor, battery pack, controls and harness. For safety, all high-voltage terminals are sealed or isolated, and the harness is colored bright orange.
What type of footwear should be worn when working on hybrid electric vehicles?
Vehicle Technicians working on Electric Vehicles (EV) or Plug in Hybrid Electric Vehicles (PHEV) are required to wear Insulated Safety Footwear due to the voltages present in the vehicles battery packs. … Class 0 insulated safety footwear is suitable for trained technicians performing maintenance and diagnostics on EVs.
What are the safety issues for working on an electric vehicle?
The main dangers in hybrid and electric vehicle repair are electrocution and the possibility of the car turning on accidentally while work is being performed. These serious risks make safety training a priority.
What are the dangers associated with working on hybrid and electric vehicles?
Risks of working with E&HVs
the storage of electrical energy with the potential to cause explosion or fire. components that may retain a dangerous voltage even when a vehicle is switched off. electric motors or the vehicle itself that may move unexpectedly due to magnetic forces within the motors.
When working on a hybrid vehicle how many volts should the protective gloves be rated to handle?
It is generally accepted by the vehicle makers that Class 0 gloves are a good choice when working on hybrid electric vehicles, as they are rated at 1,500 volts DC maximum use voltage.
How safe are hybrid car batteries?
Hybrids cause no greater concern for passengers or rescuers in the event of a collision than non-hybrid vehicles. The batteries are sealed in a protective metal case and insulated from the vehicle body.
Are hybrid batteries hazardous?
Recycling is an important aspect of the battery’s journey, even though the lithium-ion batteries used in most EVs and plug-in hybrids and the nickel-metal hydride batteries used in most conventional hybrids are not considered toxic.
What is hybrid hazard?

What safety equipment should be worn when working around the high-voltage of a hybrid or electric vehicle?
Electrical Safety Gloves – these are the first line of defence for contact with energized components. Most EV manufacturers recommend that insulated rubber gloves should be worn when working near all high-voltage components, not just the vehicle batteries.
How does the 12v battery charge in a hybrid?
A hybrid electric vehicle cannot be plugged in to charge the battery. Instead, the battery is charged through regenerative braking and by the internal combustion engine. The extra power provided by the electric motor can potentially allow for a smaller engine.
How do you stop a high-voltage circuit?
The high-voltage system is deactivated by first switching on the high-voltage system, ie putting it under high voltage (“KU 5 on”) . The motor vehicle or at least the high-voltage system is switched to the operating state by means of an “ignition key” or other starting device.
