Some components of EVs, such as electric motors, rarely need maintenance and can last the whole life of the car. For instance, they don’t require oil changes. Additionally, consumables like spark plugs, filters, and belts don’t need to be changed on a regular basis as all of these are not present in an electric motor.
The rest of an EV, however, is the same as a gasoline or diesel vehicle. Another component is the batteries, which, similar to the batteries used in phones, computers, and tablets, need to be charged. In addition, the batteries used in an EV may eventually degrade.
However, EV makers take great care to guarantee that the vehicle battery pack is going to last a very long time. They are aware that compared to buyers of regularly swapped rechargeable gadgets, their customers demand much longer periods of trouble-free use.
Jucer is a company that can provide you with all parts and accessories for your EV including ev charging cable too.
The majority of auto manufacturers often chose stronger cells to create their battery packs, also take steps to lower their stress levels, and then add technologies to make them long-lasting. Cells struggle to handle being fully charged or discharged. As a result, automakers opt to employ the majority of their battery’s nominal capacity.
Additionally, specialized software regulates the temperature of EV battery packs. Both high and low temperatures expedite the decomposition of individual cells by causing chemical reactions within the cells. Battery packs feature built-in heating and cooling mechanisms to maintain a comfortable internal temperature.
The cooling system will be crucial because the sustained high rate of charging or discharging might cause battery pack heating. Also, the heating system is necessary since extremely low ambient temperatures affect a battery pack’s capacity to retain energy.
The battery packs used in cars are certain they will provide the owners with the type of life they desire. Additionally, they support their faith with warranties. The battery packs come with an eight-year/160,000-kilometer warranty from Mercedes-Benz and Jaguar. They promise that after that time, at least 80% of the initial capacity will still be present.
In conversations with engineers, it was learned that the worst-case scenario that may arise from persistent use in adverse weather and frequent rapid charging is losing 20% over eight years. Batteries should often last considerably longer.
Tesla likewise provides an 8-year warranty on the battery, but after that period, the company only promises that 70% of the capacity will remain. Nissan compromises by offering a warranty that lasts eight years (but only for up to 200,000 kilometres of driving) and a capacity guarantee of seventy-five percent.
In contrast, Apple guarantees that the battery in its iPhones will hold 80% of its charge for a year.
Most people will charge their electric vehicles at home, providing they have a wall box for overnight charging. However, if you are out then more and more charging stations are opening, usually in malls or parking lots.
In the long run, Australia is likely to adopt the Norwegian model, where gas stations expand their premises to include charging stations.
