ABS actuator replacement – 2007 Toyota Prius Hybrid Car Repair
Complete Hybrid Car Care at Auto Service Experts
Hybrid electric vehicle (HEV) repair and service require specialized equipment & parts and highly qualified mechanics. While many regular maintenance needs are similar to those of typical gas-powered vehicles, some of the most critical steps in hybrid car maintenance are very specific to these vehicles. The traditional and electrical components and systems within HEVs are intricately tied to, and dependent upon one another. A problem in any one of these components can simultaneously affect several different systems. Therefore, it often requires extensive diagnostics by a highly specialized HEV technician to pinpoint the exact source of the problem and properly repair it.
Auto Service Experts mechanics are professionally certified by the National Institute for Automotive Service Excellence (A.S.E.) in all areas of vehicle repair and maintenance. Our extensive experience in HEV repair encompasses HEV transmission repair and service, electric motor repair, hybrid electric air conditioner repair, electrical diagnostics, battery replacements, ABS/brake system repair, cooling system repairs, and more.
This video explores the benefits and drawbacks of various alternative fuel vehicle types, which help reduce harmful emissions and fossil fuel usage. Flex-fuel vehicles are designed to run on regular gas or E85 fuel. E85 is a mixture of 15% gasoline and 85% ethanol, which can be manufactured from corn.
Alternative Fuel Vehicles
- Diesel engines offer excellent performance and increased fuel economy, and diesel fuel can be made from renewable sources.
- Natural gas vehicles are designed to operate on compressed natural gas, which is more affordable than petroleum gasoline and less damaging to the environment.
- Plug-in electric cars do not require gasoline but must be connected to an external power source to recharge their battery.
- Hybrid cars rely on an electric motor (powered by a rechargeable battery) which works together with an internal combustion engine (powered by gas or diesel fuel).
- In mild hybrids, the electric motor only assists the gas engine under certain conditions.
- Full hybrids rely more heavily on the electric motor, and their small combustion engines are used to recharge the battery.
Many hybrids also utilize regenerative brakes, which capture the energy generated during braking and use it to recharge the battery. Hydrogen fuel cell vehicles convert hydrogen and oxygen into electricity, which powers the electric motor and releases water vapor instead of pollutants. With constant technological advancements in the automotive industry, alternative fuel vehicles are becoming increasingly viable, offering enhanced performance and providing numerous benefits to both drivers and the environment.
HEV Batteries
HEV batteries are very reliable, lasting around 10 to 15 years (usually between 120,000 to 150,000 miles, or more). For this reason, they typically come with excellent warranties and are well worth the initial seemingly high cost. Hybrid battery failure, however, is possible at much lower or higher mileage, depending on the individual vehicle. As with all automotive components, some makes and models offer specific performance and durability advantages. In the event of failure, first, check your warranty to see if the vehicle is still covered. Warranties vary not only according to manufacturers and dealerships but also according to differing state laws.
New Hybrid Battery Replacement
New HEV batteries can be costly, however, this is an investment which is likely to last another 10 years or longer. This is often the best long-term option as you will get the most warranty coverage and can expect the lifetime and performance to be on par with the original unit that came with the vehicle. Because different types of batteries vary in cost and lifespan, there are some cases where new battery replacements may not be financially sensible. When the vehicle no longer holds enough value to justify spending a few thousand on a new replacement, there are other options to consider.
Reconditioned HEV Battery Replacement
Rebuilt or refurbished HEV batteries cost much less than new ones and can help keep your vehicle on the road for several more years. These batteries are made up of many cells or modules. Often, when battery failure occurs, it is due to a dead cell that can be located and replaced individually.
Used Hybrid Battery Replacement
Used batteries are sometimes available from vehicles that were parted out after suffering body damage or other malfunctions not involving the battery. The cost is significantly lower, making this a viable temporary alternative to purchasing a new one. However, as with most used parts, they involve more risk and fewer guarantees of lifetime and performance.
HEV Operation
Hybrid motors – Combine electric motors with small internal combustion engines similar to those in gas-powered vehicles.
Internal combustion engine – These engines run on gasoline and operate similarly to traditional automobile motors. However, they are considerably smaller, lighter, and designed to handle smaller loads. Their smaller size and efficient design require much less fuel to operate, therefore reducing the emissions released into the atmosphere.
Electric drive motors – Hybrid batteries power the electric motor, it draws energy from the batteries and also returns it to them. It is designed to help the small internal combustion engine carry the workload under more strenuous conditions, such as driving on an incline. There are some driving conditions in which the electric motor operates without any assistance from the internal combustion engine,e such as cruising and maneuvering the vehicle at low speeds.
Hybrid batteries – These rechargeable batteries store energy and supply electricity to the electric motor. Charging is handled by a charging system within the vehicle. This allows the unit to store energy without needing to be plugged into an external power source (as required with completely electric vehicles).
Regenerative braking systems – Heat generated from friction within the braking system is converted into energy and stored in rechargeable batteries. Regenerative braking also offers the additional benefit of reducing wear on brake system components.
Vehicle charging control system – These sophisticated, computer-controlled electronic units control the operation of the electric drive motor, regulate charging, and monitor temperature. They are often connected to cooling systems specifically designed to handle the extreme heat generated by both electric motors and regenerative braking. By using cooling and integrated heating systems, the charging control unit monitors and makes adjustments to maintain the proper operating temperature.
