Electric vehicles (EVs) produce no tailpipe emissions; however, their batteries still rely on electricity generated from fossil-fuel-powered grids for powering their operation.
Battery capacity determines how far an electric vehicle (EV) can travel between charges. Driving at high speeds or using heating elements will quickly deplete a battery’s reserves, shortening its range between recharges.
How it works
Electric vehicles (EVs) do not rely on traditional gas/diesel engines or fuel tanks; rather, they use an electric motor which converts electrical energy to mechanical energy to propel the vehicle forward. Furthermore, EVs offer simplified gear systems making driving them much simpler than cars with internal combustion engines.
An electric vehicle’s core component is its battery, which stores electrical energy to power its electric motor and accessories. Consumers should take great care in selecting their battery pack when looking to purchase an EV; after all, its lifespan must last long enough for drivers to travel without needing recharges between each destination. A battery’s fuel economy rating provides information about how many miles its energy equivalent of one gallon of gas it covers per cost; or its gasoline-equivalent rating (GGE rating).
A battery for an EV consists of multiple modules and cells working together to generate energy necessary for its proper functioning. Most commonly, such batteries contain several hundred lithium-ion cells with voltage between 3-4 volts.
As soon as the car’s controller detects that you are pressing down on the accelerator pedal, its battery quickly feeds electrical energy to an electric motor that quickly transforms it into mechanical motion that the transmission sends out to wheels. When brakes are applied, that same electric motor serves as a generator and returns some of that energy back into its battery as electrical energy.
Compared to gasoline engines, which convert most of the energy they burn into heat, electric motors are up to 90% efficient. Their rotor feels the force from each rotating magnetic field; those opposite each other attract while similar fields repel. This movement then generates force that drives axles that turn wheels.
A DC-to-DC converter converts high voltage battery pack current into low voltage current that powers auxiliary equipment such as lights and horn. An onboard charging system also includes conversion of AC electricity supplied from charging stations into direct current that can be used to recharge the battery pack.
Range
Recent years have witnessed a revolution in battery technology. As a result, electric vehicles (EVs) can travel hundreds of miles on one charge – more than conventional petrol or diesel cars! For instance, MINI Electric Level 1 boasts a range of 144 miles while Tesla Model S Long Range can travel 379.
Regenerative braking systems on EVs are another factor which contributes to their range extension. By converting kinetic energy to electricity for recharge of their battery pack, these slowing mechanisms help the car halt when travelling on steep inclines or at high speeds – especially beneficial during steep inclines or at higher speeds.
Other factors can also impact an EV’s range, including accessories and weather. Running air conditioning uses more power than driving without it while cold temperatures reduce battery capacity by 35% – this is why investing in a home charging station may help warm up your battery before embarking on winter journeys.
To maximize the range potential of your electric vehicle (EV), it is wise to maintain a steady, constant, and moderate rate of speed. Furthermore, making sure that you use regenerative braking to its full extent can help to extend its reach even further.
Although the world of electric vehicles (EVs) is filled with exciting innovations, its world can be overwhelming for anyone trying to buy one. One way of assessing whether an EV fits with you is researching its range capabilities compared to traditional petrol or diesel cars; once this research has been completed, finding one to suit your needs should become much simpler – and we make this easier still by categorizing our new models based on maximum EPA-estimated driving range.
Recharging
EVs can be charged in one of several ways. For the fastest and simplest charge, plugging it into an electrical outlet – either at home or public charging stations – will quickly provide sufficient energy. Onboard chargers will then convert AC electricity into DC power for use by the electric motor to drive wheels; additionally, this energy storage battery stores energy as the car slows or stops, converting kinetic energy back into electrical energy storage capacity when necessary.
The battery is the most costly component in an EV, yet its lifespan far outlives any gasoline or diesel engines. Chemical components within its makeup degrade more slowly than other car components and can keep working for tens of thousands of miles before needing replacing.
Electricity is now more economical per mile than gasoline, and this trend is expected to continue into the foreseeable future. Another advantage of EVs is no tailpipe emissions or environmental impact as production and use of energy reduce.
Car manufacturers are currently competing to increase vehicle range by equipping cars with larger batteries to extend driving range and allow drivers to travel further between charges. Unfortunately, this requires mining and refining more rare earth metals from mines around the globe and leaving an increased carbon footprint behind.
Current EV drivers typically charge their cars either at home with standard three-pin plugs, or through public charging stations found at malls, restaurants and retail locations. Public charging stations have become increasingly popular over time and can especially come in handy during long road trips when returning home would not be worth your while to refuel your battery pack.
Many electric car owners choose to top off their batteries at convenience stores or supermarkets when driving out of town, though experts advise against doing this before it reaches 50% of its full capacity; doing so would reduce reserve capacity over time and may eventually cause it to fail early.
Maintenance
As long as your electric vehicle’s battery doesn’t become depleted (which can happen if you frequently go for extended periods without driving), its built-in discharging and charging process should maintain optimal health – thus prolonging its lifespan. A car battery functions much like an energy storage unit storing energy efficiently to fuel its components like electric motors, air conditioning units and high-quality audio systems.
Even though electric vehicles (EVs) contain fewer moving parts than gas-fed cars, they still require periodic maintenance in order to run smoothly and efficiently. This may involve both familiar tasks such as oil changes, cabin air filter replacement and windshield wiper blade installation as well as more EV-specific services like tire rotations, coolant flushes and battery inspections.
Most EV owners can complete many of these services themselves, although for best results it is always wise to refer to your owner’s manual for more specific guidance on when and what services should be performed. For instance, certain models with specialty tires need more frequent tire rotations than standard rubber vehicles in order to maintain even wear and maintain optimal handling capabilities of the vehicle.
Electric vehicles equipped with lithium-ion batteries often include an onboard cooling system to prevent overheating and degradation, with automakers often offering warranties covering the cost of replacement packs if they degrade beyond certain thresholds, though coverage varies based on carmaker and model year.
As modern EV batteries only support limited charging cycles, it’s crucial that owners abide by manufacturer recommendations in order to maximize battery longevity and ensure its optimal use of power-management features. This includes not leaving it exposed to extreme temperatures or overcharging it.
Even if your electric vehicle (EV) comes with an extended battery warranty, it is still recommended that you visit a service center specialized in these cars for routine checks and servicing. Professionals here can perform diagnostics to keep the battery performing at peak condition while battery replacement services could provide support should its performance decline significantly over time. If necessary, one of these specialist centres could also help provide solutions if a replacement becomes necessary in future.
