What component should be removed when working on a hybrid vehicle?

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 …

What are the main components of a hybrid vehicle?

Regardless of the type of hybrid electric vehicle (HEV), the propulsion system is composed of at least the following components: a prime mover; an electric motor with a DC-DC converter, a DC-AC inverter, and the controller; an energy storage system (ESS); a transmission system.

When working with a hybrid vehicle HV What are some safety precautions that need to be taken?

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 is the danger of working on a hybrid vehicle?

Risks of working with E&HVs

These include: the presence of high voltage components and cabling capable of delivering a fatal electric shock. 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.

What are the precautions that service technicians should adhere to when working on hybrid electric vehicle?

Always disconnect the high-voltage hybrid battery before doing any major repair work or electrical work, he recommends. Most manufacturers also recommend waiting at least 10 minutes before working on the vehicle after the battery has been isolated or disconnected.

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.

Which is the most important component of hybrid vehicle?

The prime mover of a hybrid vehicle is its main energy source, which generally is one of gasoline, diesel, or fuel cells. The electric motor is one of the most important components in a hybrid vehicle.

Which type of hybrid system needs IC engine?

Parallel hybrid

These vehicle types have two drive systems – an electric motor and an IC engine. Both can move the vehicle forwards and are connected with the driving axle. They are deployed as required: the vehicle can be driven purely electrically, with only the IC engine, or with a combination of both.

What’s the difference between a hybrid and a plug-in hybrid?

Standard hybrid vehicles rely on their gas engines to keep their batteries charged as you drive. Standard hybrid vehicles use their gas and electric motors interchangeably to maximize your fuel efficiency. Plug-in hybrids use a larger battery that is charged with a 120-volt or 240-volt outlet at your Tampa home.

What is the best indicator that it is safe to work on a hybrid electric vehicle?

To address safety concerns, car companies have developed certain indicators that can help workers identify the vehicles: Color-coded high voltage cables in hybrid and electric vehicles warn of their potential danger. Usually these are orange but some models have blue cables instead.

What actions are needed to disable the 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.

When servicing a hybrid vehicle and removing the high-voltage service plug How long should you wait?

Wait a minimum of 5 minutes before servicing the high voltage system. High Voltage Reconnect Procedure is: 1. While wearing insulated gloves, install electric vehicle fuse and service plug grip cover.

Can a technician be electrocuted when working on HEVS or EVs?

“Once they are trained, the most important rule technicians need to remember is this: Never work on a high-voltage vehicle without first notifying someone who is trained in dealing with high-voltage electrocution,” they say.

Can you get electrocuted by a hybrid car?

Activated airbags in electric vehicles

If, in the event of an accident, the airbags of an electric or hybrid vehicle are activated, there is no risk of electrocution from the bodywork. This is because the power supply from the high-voltage battery is automatically switched off when the airbags are activated.

What components does a high-voltage battery contain?

The high-voltage battery system uses lithium-ion cells, which are also used in mobile phones and notebooks. A single battery cell is the smallest unit in the battery system. It can store energy and release it again. 24 of these cells are currently consolidated into one battery module.
