Under the Hood of the New EV Battery Study

A new study was recently done by scientists in the SLAC-Stanford Battery Center. This center is a joint venture between Stanford University’s Precourt Institute for Energy and the SLAC National Accelerator Lab.
They found that batteries used real-world conditions such as heavy traffic, short trips in the city, and even long highway trips lasted longer than the batteries that were originally tested in the lab. In the lab, they simulated use by creating a constant rate of discharge and then recharging.

What Did the SLAC-Stanford Battery Center Do?

The SLAC-Standford Battery Center conducted their test differently than the previous battery tests. They replicated real-world conditions and driving patterns by designing different discharge patterns based on real data. They tested 92 lithium-ion batteries for over two years using a variety of different scenarios such as electronic starting and stopping, to mimic real conditions.

What Did They Find?

Once batteries were being used out in real driving conditions, including long periods of being parked, they realized that the way they were testing the batteries in the lab was not a good way to predict the life expectancy. Other driving habits such as frequent acceleration, braking the charges the battery, and letting the battery rest for several hours such as overnight, helps them last up to 40 percent longer.

So What Does This Mean for EV Drivers?

What does this pleasant surprise mean for people who already drive electric vehicles or are looking into buying electric SUVs? It means that EV drivers could save a significant amount of money in the long run.
One of the things that was holding some car buyers back from choosing an EV over a gas vehicle was the idea that they would have to replace the battery, Now, they can feel more comfortable with the idea of an EV, knowing that the replacement is many years down the road. Batteries that last longer help reduce the overall cost of owning an EV.

What Affects Battery Life

EV batteries can last 10 or 20 years, but there are many things that can have an effect on how long they last. One of the biggest factors is battery chemistry. There are two main types of batteries found in EVs: lithium-ion and nickel-metal hydride. Most EVs have lithium-ion batteries.
In addition to the type of battery, the environmental conditions can impact its lifespan. Extreme heat and cold can affect the chemical process. DC fast charging is another factor that can affect battery life. Frequent use is linked to faster degradation.

What Drivers Should Consider Before They Buy

Everyone knows the benefits of buying a new EV. Electric vehicles don’t use fossil fuels, reducing their environmental impact and saving drivers money. These days, most used car dealerships have at least one or two in their showrooms. But are they worth buying?

Batteries Are the Biggest Worry for Used EV Buyers

Electric vehicles have fewer moving parts than their gas-powered alternatives. Fewer moving parts means less to go wrong, and EV owners’ typical driving habits further improve the situation. The limited range of most EVs means people don’t drive them as far.

What most drivers worry about when buying used EVs isn’t the general condition of the cars but the batteries. Most major battery components come with manufacturers’ warranties, and the EVs found at used car dealerships are usually well within the eight-to-ten-year warranty periods.

The flip side of the coin is that when EV batteries reach the end of their warranty periods, they are expensive to replace. The cost of purchasing a new battery pack starts at around $4,000 and can range as high as $10,000 for some models.

Eco-Friendly Drivers Can Do Their Part for the Planet Twice

Buying an EV takes one more combustion-powered engine off the road. That’s good for the environment since the pollutants emitted by traditional gas-powered cars contribute to climate change.

Buying any vehicles at used car dealerships is also better for the environment since it reduces the need for natural resource extraction. The initial manufacturing of an electric vehicle has a larger carbon footprint. Drivers who buy them new don’t start making up for the higher manufacturing emissions for 6 to 18 months.

Used EVs have already offset their initially higher emissions. Buying them instead of going for brand-new models right off the factory lines means drivers are doing their part for the future of the planet not once but twice.

Used EVs Don’t Make Sense for Everyone

That EVs run off electricity instead of gas is what sets them apart from traditional vehicles with combustion engines. Unfortunately, it also makes them a poor choice for some drivers.

EVs require frequent charging and older models have shorter ranges and lower battery capacity. Drivers who don’t have a place to plug in at home may find themselves at a disadvantage. The price of public charging stations varies significantly.

Renters may have difficulty convincing landlords to install dedicated 240-volt plugs. Plus, not all homes can support EV charger installation. If a home has old wiring, an electrician will need to fix it. Even if the house has modern wiring, installing an EV charger can cost thousands of dollars.

All these factors make it essential that buyers consider whether a used EV is the right solution. Talking to experts at reputable used car dealerships about the pros and cons of purchasing an electric vehicle can make the decision easier.
