Recognizing Signs of a Bad Electric Vehicle Battery: How to Determine if Your EV Needs a Replacement

The adoption of electric vehicles (EVs) in Nepal is increasing as the country relies on importing gasoline and diesel and producing electricity from domestic water sources. This makes EVs an attractive option for reducing dependence on imported fossil fuels and promoting the use of domestic resources.
However, despite this increasing interest in EVs, there are still some major complaints among those considering purchasing an EV.

The first major complaint is the lack of charging infrastructure. In Nepal, charging stations are not as widespread as they are in other countries, making it difficult for EV owners to find a convenient place to charge their vehicles. This can make it difficult for EV owners to plan long trips or to rely on their EV as their primary mode of transportation.

Another major complaint is the limited driving range of EVs. Because EVs run on batteries, they have a limited amount of energy that they can store and use to power the vehicle. This means that the distance an EV can travel on a single charge is limited, which can make it difficult for EV owners to plan long trips or to rely on their EV as their primary mode of transportation.

The cost of replacing a bad battery is also a major concern for many people considering purchasing an EV. Because EVs run on batteries, the battery is a critical component of the vehicle. If the battery goes bad, it will need to be replaced, which can be costly.

To combat these complaints, information is being made available to help people understand when an EV battery is going bad and what signs to look for. This will help EV owners to recognize when their battery is going bad and to make an informed decision about whether to replace it.

Many manufacturers in the market have given a warranty of around 8 years on their car battery packs. Companies are claiming that the battery can be used for 10 years if used properly. Two-wheeler batteries come with a warranty of 3 to 5 years.

To determine if a battery is bad, EV owners should look for signs such as decreased range and the need to charge frequently. If an EV’s range is reduced and it needs to be charged more often, this may indicate that the battery is going bad.

Battery damage can also occur from improper charging. Overcharging with a fast charger or discharging and recharging the battery to 100% can reduce the battery life. To prolong battery life, it is recommended to charge EV batteries when they are above 15% and to avoid charging them to more than 80-85%. Additionally, weather conditions can also affect battery efficiency, with EVs used in cold regions having shorter battery lives than those used in hot regions.

In summary, while the adoption of EVs in Nepal is increasing, there are still some major complaints among those considering purchasing an EV. These include the lack of charging infrastructure, limited driving range, and the high cost of replacing a bad battery. To combat these complaints, information is being made available to help people understand when an EV battery is going bad and what signs to look for. Additionally, manufacturers offer warranties on EV batteries, and it is recommended to charge EV batteries when they are above 15% and to avoid charging them to more than 80-85%.
