  • CHARGING

    It cannot be denied that electric cars (EVs for short) completely change the approach to car operation. Users do not have to worry, e.g. checking and changing oil, but should learn how to care for the battery. What should you remember when using a battery-powered vehicle? We have prepared for you some of the most important tips.

    Basic rules

    Do not charge fully!

    Do not unload to zero!

    Charge more often and less!

    Charge at night!

    Loading full? Unnecessary! 

    According to the latest survey by InsightOut Lab and the Volkswagen brand, which was conducted at the beginning of April 2020 on the Ariadna panel on a nationwide sample of N = 1101 people, the average daily distance covered by the car by respondents was 51.3 km. However, the 2018 GUS survey [1] shows that the average daily mileage of cars in Poland is 37 km (13 426 km / year).

    So does the EV user have to charge the battery to "full" every day? 

    Definitely not. Not only does he not have to, but he shouldn't. Charging to 100% capacity shortens battery life!

    Why? Frequent battery charging, as in the case of a mobile phone, significantly shortens its lifetime. Many electric cars now have so-called long battery life modes, thanks to which the charging ends automatically when it reaches the 80% battery level.

     

    So when should you charge the batteries to 100% capacity? In principle, only when we are planning a longer journey and maximum range are we needed or, in accordance with the recommendations of e.g. Tesla, at least once every three months in order to balance the cells (i.e. equalize their tensions).

    Remember - Do not discharge the battery to zero! 

    An important rule in everyday use of an electric vehicle - never use 100% battery capacity.

    Why shouldn't the battery be fully discharged?

    If the lithium-ion battery is fully discharged, it could damage it and shorten its life cycle. Fortunately, car manufacturers have equipped cars with systems to prevent this type of event, but despite all this, the user may have an unplanned stop if the route is not properly planned.

    It is better to charge more often and less 

    The makers of lithium-ion batteries have no doubt about that. Given the battery life cycles, the optimal charge level for most current technologies is in the range of 50 - 80%.

    But how to achieve it?

    Simply - follow the first rule described above - i.e. do not charge the battery more than 80%, and if possible when the amount of energy in the reservoir drops below 50%, recharge the battery, among others while in the city.

    When is the best time to charge the batteries - time matters! 

    When to charge an electric car?

    It is best to connect the car to the charging station at night - then the charging time does not matter, and the driver can benefit, among others from the cheaper night tariff, in addition, we do not burden the network then, most other energy consumers are then switched off. The manufacturers of chargers and EV vehicles know this very well, which is why they allow you to program the working time of the charger.

  • Fast charging

    Refueling a car with a traditional combustion engine to full with payment takes several minutes. Unfortunately, electric vehicles cannot be charged as quickly, although it will probably be possible in the near future.

    Example? DC stations (DC charging) are now available to replenish 80% of the battery's energy reserves in just 30 minutes. Charging time is a key indicator from an operational point of view and forms the basis of many fears and reasons why many potential buyers refrain from buying an electric car, although at the same time it indicates that they would like to drive such a vehicle in the future.

    However, there is a caveat when it comes to fast loading ...

    Fast DC charging (DC stations) should be used only when it is necessary - e.g. when driving on the road or when the driver has to use the car very quickly, because too frequent use of this method of charging the battery may translate into a reduction in its capacity and shortening its life cycle.

    In sum:

    The most important and most sensitive element of electric cars are batteries. Therefore, special care should be taken to extend their lifetime. It is not difficult in practice, but requires the EV user to develop certain habits that, used in everyday life, will allow you to effectively use the potential of the car, without worrying about the range and battery life.

  • Use in extreme weather conditions

    Baterie litowo-jonowe w samochodach elektrycznych są bardzo wrażliwe na zmienne warunki cieplne. Co to oznaczaLithium-ion batteries in electric cars are very sensitive to changing heat conditions. What does it mean?

    For example, in the summer heat it is better not to park the car in the sun and find a shady place. This protects the battery cells from overheating. In the winter season, however, it is important to ensure that the batteries are not exposed to very severe frost. It's best to leave the car in a garage or underground car park.

    Of course, there are currently solutions that allow you to take care of the battery condition even when the car is exposed to adverse weather conditions. Most vehicles are equipped with battery management systems that will cool the cells in the summer and warm them in the winter. However, it should be remembered that energy consumption increases then - which in turn translates into a significant reduction in the range that the driver will have at his disposal.
