Electric cars have become a common alternative fuel transport. Widespread charging stations, multiple auto brands launching electric cars and fluctuating fuel prices across the globe have contributed to the rise of EVs. Electric cars are simple and analogous to the digital watch. That said, EVs have a battery and less complex parts.
Generally, an EV has fewer moving parts than a conventional car, which leads to fewer breakdowns and mechanical issues. However, it may have a different set of problems related to battery and other parts.
Here are all the problems with EV batteries and tips to avoid those issues. However, let’s learn the basics about electric car batteries.
Electric Car Battery Basics
An electric car features a lithium-ion battery. Automakers are testing solid-state batteries but lithium-ion ones are the most common in EVs. It is one of the problems with EV batteries that lithium is a rare metal. Lithium batteries are expensive to produce and mining lithium is an environmental concern.
Electric car batteries have many pros and cons. Let’s go through some basic EV battery considerations.
Battery Life
The problem with electric car batteries is that they are quite expensive. Speaking of that, an EV buyer needs to consider the battery life expectancy. For instance, Tesla provides coverage of 100,000 miles (160,000 kilometres) or an eight years warranty.
While the battery coverage and warranty depend upon the auto makes and models, these warranties guarantee against battery degradation. Additionally, many EV manufacturers guarantee that the battery won’t degrade more than 30% during its warranty period. That said, the battery will have 70% health even after 160,000 kilometres or 8 to 10 years.
Safety and Maintenance
A lithium-ion battery has a potential drawback that it may overheat and catch fire. It isn’t common, but the automakers have identified this problem with electric car batteries and taken necessary design precautions.
EV batteries are encased in sealed shells. Alongside, manufacturers use insulated high-voltage lines to deactivate electrical systems in case of a crash.
Plus, the maintenance of an electric car is simpler than that of conventional vehicles. For instance, when you compare electric, hybrid or conventional cars, the IC engine cars and hybrid cars require more maintenance due to mechanical parts wear and tear. Moreover, EV batteries have a longer coverage and warranty period saving hefty maintenance costs.
Battery Charging Cycles
Charging also affects battery life. It is common practice that car owners don’t fuel up the car until it completely runs out of it. Given the ease of charging EVs at home, many electric car owners have the convenience of charging.
Additionally, EV manufacturers recommend charging the battery up to 80% and not using the DC fast chargers regularly for longer battery life.
Battery Thermal Management Systems
The EV battery thermal management systems help keep the batteries in optimal temperatures between 10°C to 35°C. That said, this temperature range helps provide peak performance. A thermal management system maintains the battery pack temperature by heating or cooling circuits.
EV owners can use preconditioning features in electric cars to heat or cool the battery and interior with electricity from the power grid while charging. It helps preserve the battery’s health and performance. One can follow tips to improve EV performance in different weather conditions to avoid battery health degradation.
Issues with Electric Car Battery
Multiple problems of electric car batteries require immediate attention for optimum performance. Here are all the common problems with batteries in electric cars.
Faulty or Damaged Separator
The main purpose of a separator is to create a boundary between the anode and cathode. The separators are thin and once they damage, the anode and cathode in EV batteries come in contact.
It is one of the most common issues with EV batteries that can occur due to overcharging. When the separator is damaged, it causes a short circuit due to the direct contact between the anode and cathode.
Temperature Sensitivity
Another problem with electric car batteries is that they may degrade due to extreme temperatures. Extreme cold or hot temperatures can change the reaction’s timing. For instance, extremely hot temperatures lead to faster reactions across the board.
That said, it is an essential tip for EV owners in hot weather to use the preconditioning feature and use fewer applications to avoid battery overheating. Besides, the following cooling systems in electric cars help boost the EV battery life and performance:
- Air Cooling
- Liquid Cooling
- Phase Change Material
- Cooling Fins
Internal Electrical Imbalance
Frequent charging and discharging cycles cause electrical imbalance and may result in short circuits. Lithium-ion batteries have a separator that damages due to under or overcharging the electric car. Speaking of under or overcharging, an EV battery may short-circuit or explode due to electrical imbalance.
Difficult to Recycle
The design and efficiency of EV batteries have improved over the years. However, a common problem with electric car batteries is that they are difficult to recycle or dispose of.
EVs have fewer emissions than conventional cars but the batteries include nickel, manganese, and cobalt. These materials are a hazard to the environment.
Although it is difficult to recycle EV batteries, auto manufacturers reuse these batteries to power machinery in industries.
Long Charging Times
EV battery packs are bigger and require long charging hours. However, if you own an electric car, the DEWA EV chargers in Dubai include DC fast chargers that charge the vehicle in half an hour.
Moreover, if you are using slow EV chargers (AC chargers), you can follow the tips to overcome boredom while your electric car charges.
That wraps up the basics of an EV battery and common problems with electric car batteries. As the EV market rapidly grows, automobile manufacturers are developing efficient designs for EV batteries. That said, it will reduce the problems of electric car batteries.
You can find EVs in the listings of used cars for sale in the UAE and choose the environmentally-friendly vehicle for your daily needs. Moreover, you can follow tips for new EV owners to maintain the optimum performance of your electric car.
