Hybrid vehicles work by powering off the engine when they are not in motion on the road, such as at a stop light or in traffic, which is considered idling. Hybrid-electric vehicle technology uses idling to achieve fuel savings of nearly 15% according to the U.S. Environmental Protection Agency (EPA) and is a great choice for consumers who are environmentally conscious or want to save money at the pump. However, you should understand some key insights about letting your hybrid vehicle sit idle for too long.

With more professionals working from home, it is all too easy to let your hybrid vehicle sit completely idle in your garage for long periods of time. However, if you do not start up and drive your hybrid regularly, you run the risk of causing serious issues to your battery pack.

need exercised weekly at a minimum to prolong your hybrid vehicle’s performance. But remember, there are also other ways a vehicle can idle.

The exact length of time that you can let a hybrid car, truck or SUV sit completely idle without being turned on varies by the make and model. If you’re working from home and not driving as much, make sure to turn your hybrid vehicle on in a ventilated area and let it run for at least a few minutes each week to exercise the battery pack. If you cannot turn the vehicle on at least once a month, consider having a friend or trusted neighbor do it for you.

If you have to let your hybrid sit idle without powering it on for more than 30 days, inspect your vehicle or take it to

to prepare for your absence. Store the hybrid vehicle in a well-ventilated area or garage that is free of moisture, ensure any interior lights or plug-in accessories are turned off and rest easy knowing you’ve prepared your prized hybrid vehicle for a long absence.

Do Hybrid Vehicles Use Gas While Idling?

Hybrid vehicles use a combination of gas and battery power to function and can include an array of features like idle-stop systems where energy is transferred from the gasoline engine to the electric starter and back to the generator/battery. An idle-stop system (also commonly known as the start-stop system) helps drivers save gas by powering down the engine (idling) when the vehicle comes to a halt for even a short period of time. Imagine you brake at a red light—the hybrid engine automatically shuts down to save on gas. Then, when you release the brake pedal to accelerate, the engine starts back up again.

The idle-stop system makes up today’s market of hybrids that can come standard in both mild hybrids and full hybrids. Mild hybrids that use idle-stops are typically conventional combustion engine vehicles that simply idle when not in motion, but do not take advantage of an electric motor that full hybrid vehicles possess. So, which type of hybrid electric vehicle has an idle-stop operation? The answer is that many mild and full hybrids now come with idle-stop technology, shutting off the gasoline engine when at rest, coasting or slowing down.

Due to idle-stop, no gas burns inside the engine, saving you money while saving the planet at the same time. NAPA thanks you for doing your part to reduce the heat island effect, which happens in large metropolitan areas where air quality and pollution is affected by vehicles that have high carbon emissions from fossil fuel. According to Reuters, U.S. hybrid vehicle sales increased a whopping 76% in 2021 and is on pace to continue growing sales. Additionally,

estimates that the hybrid-electric vehicle market was worth $252 billion in 2020 alone and may reach as high as $1,165 billion by 2026. Even Ford Motor Company predicts that electric vehicles will make up 40% of its sales by 2030.

How Long Can a Hybrid Vehicle Sit Idle?

As you cruise along in your planet-loving automobile, just as you start to brake, the hybrid’s stop-start system will engage the regenerative braking system. Regenerative braking uses rotational energy from your wheels to create electricity for your generator in a full hybrid vehicle model. The generator then sends the electricity to your battery where it is stored and used later as your energy reserve.

As the brake is fully pushed, the generator shuts down the gas flow. Stepping on the accelerator again restarts the engine and uses that stored energy, running it to the

. If you have a full battery, hybrid vehicles can idle for nearly two hours. Of course, this figure can scale up or down depending on your hybrid’s make and model.

      The Best PPE For Your EV & Hybrid Service Shop
      By NAPA
      When it comes to working in the shop, personal safety should always be the top priority. Safety glasses, gloves, hearing protection, even work boots are all meant to keep your body protected. It should come as no surprise that with new hybrid and electric drivetrains, there are also new safety gear requirements. Insulated tools are just the start of a well-stocked shop. There’s more to electrical safety than just owning a set of
      link hidden, please login to view.  This expert advice is meant to give an overview of the kinds of general
      link hidden, please login to view (PPE) needed to service hybrid and electric vehicles. It is important to follow proper repair procedures for these vehicles, as described in the vehicle specific repair manual. This includes using all required PPE listed in the repair procedure with no exceptions. If you do not have ALL of the necessary PPE, DO NOT proceed with a repair, as doing so could lead to severe injury or even death. Now that you have an idea of the serious nature of vehicle high-voltage electrical systems, let’s take a look at how you can protect yourself.  Personal Protection
      Wearing the right personal protection gear is a must when working with electric and hybrid vehicle high-voltage systems. The electrical energy stored in a typical main traction battery pack is more than enough to kill or seriously injure a person. 
      In the past, wearing gloves while working on a car was usually a personal preference. Today, when working on high-voltage electrical systems, wearing gloves is mandatory. And not just one pair of gloves, but two pairs (inner and outer) are to be worn together. Just in case you are wondering, welding gloves are NOT the same as high-voltage
      link hidden, please login to view.  Class 0 gloves are required for protection up to 1,000 volts AC and 1,500 volts DC. One pair of rubber gloves (inner) protects against electric shock, while the leather gloves (outer) protect the rubber gloves from mechanical wear. They must be worn together in order to perform correctly. Electrical gloves

Gloves will be labeled with the test date near the cuff.  The exact personal protection gear needed for a repair will be spelled out in the vehicle service repair manual procedures. This may include an insulated apron,
      link hidden, please login to view, insulated arm sleeves, link hidden, please login to view, arc flash face shield with neck protection, and insulated mats or blankets. These layers of protection are necessary not just for avoiding shocks, but also potential explosions like an arc flash. Tool Safety
      It may seem odd to consider hand tools as part of personal protection equipment, but that is exactly the case when working with electricity. Most ordinary hand tools are made from metal, which does an excellent job conducting electricity. For servicing high-voltage electrical systems tools need to be designed in such a way that they don’t provide a path for electricity to travel to the technician, or to other vehicle components. That’s why EV tools are specially designed to protect the technician when used properly. 
      An EV tool set is a must-have for any technician looking to service an electric vehicle. A good start for insulated hand tools is an insulated screwdriver set, an

Electric vehicle tools used for diagnostics need to handle higher voltages, like this link hidden, please login to view. For repairs where the battery pack must be removed, special care must be taken due the extreme weight involved. A link hidden, please login to view is the proper way to lower and transport a hybrid or electric vehicle battery pack. You wouldn’t pull an engine out of a car without the proper lifting equipment, so give the same respect to a heavy traction battery pack. Work Space Safety
      Normally, when a car is being worked on in a service bay, there is little danger to fellow technicians. But that isn’t the case with a modern electric or hybrid vehicle. Whenever the high-voltage electrical system on one of these vehicles is exposed, proper notification must be given to those working in the area. Place
      link hidden, please login to view and link hidden, please login to view around the vehicle whenever the high voltage electrical system is being serviced. This warns other technicians that there is an electrical shock hazard in the shop, and to keep their distance. You may also place an electrical warning sign on the vehicle to signal to everyone in the shop to stay away. Part of your workspace safety gear must be an

An insulated safety hook must be used to separate the victim from the electrical source. The last tip for work space safety is to never work on an electric or hybrid vehicle alone. Always let another technician or coworker know you are working on a high-voltage electrical system, and to check in on you periodically.  Training Is The Key To Safety
      Working on hybrid and electric vehicle high voltage systems requires meticulous procedures and extensive training. While there are plenty of dangers when working on internal combustion vehicles, many of the safety procedures surrounding those vehicles have been known for decades. As EV and hybrid drivetrain become more mainstream, so will their service safety procedures. 
      Tackling hybrid and electric vehicle high-voltage system repairs isn’t impossible, but there must be dedication to proper training. If you are a technician (or are wanting to become a technician), and are looking for electric vehicle service training,
      link hidden, please login to view can help. NAPA Auto Tech offers a wide variety of convenient, cost-effective ways to become an automotive professional. In addition to eLearning and instructor-led training, NAPA Auto Tech offers hands-on and seminar-style classes for almost every make and model to help technicians keep their skills up to date.
