Why are AC EV Charger not eliminated when they charge so much slower than DC EV Chargers?
For owners of new energy vehicles, the impact of AC EV Charger and other charging piles on electric cars is as important as that on traditional fuel vehicles, and the user experience of AC EV Charger directly affects the car experience.
At present, new energy vehicle charging piles on the market are mainly divided into DC piles and AC EV Charger. There are large differences in technical parameters such as current and voltage. The most obvious difference is power: it only takes 1 to 2 hours for a pure electric vehicle to be fully discharged through a DC EV Charger, while it takes 8 to 10 hours through an AC EV Charger.
According to PwC data, more than 180,000 charging piles were added in Europe in 2023, a 23.3% year-on-year increase. Among them, 39,000 charging piles and 29,000 AC EV Charger were added in the fourth quarter of 2023. However, the number of new AC EV Charger in this quarter showed a downward trend year-on-year and month-on-month, down 43% year-on-year and 25% month-on-month.
Why do AC EV Charger have low charging efficiency but account for a large proportion?
AC EV Charger have low charging efficiency but account for a large proportion. The reasons are: on the one hand, its technical threshold is not high, and the manufacturing cost is relatively low; on the other hand, DC charging piles must match the three-phase 380V voltage, and the power supply department needs to approve it separately, while AC EV Charger are adapted to single-phase 220V ordinary household electricity. The construction of DC charging piles requires the coordination of land and power grid resources. In comparison, the investment and construction restrictions of AEAUTO's AC EV Charger station are much smaller.
Since DC charging piles are the trend of the times, why do we still say that AC EV Charger cannot be eliminated?
Although DC charging piles are the mainstream, AC EV Charger are also indispensable. First, most charging piles are currently built in a centralized manner, and DC charging piles have obvious power advantages; but in the future, private charging piles will become more and more popular, and AEAUTO's AC EV Charger are low-cost and easy to install, which obviously better meets the needs of private car owners.
According to the European Electric Vehicle Development Blueprint released by the European Automobile Manufacturers Association and others, it is expected that the frequency of low-power AC EV Charger slow charging in Europe will account for more than 70% in 2025, which is highly dependent on the popularity of private charging piles.
At present, the shortage of parking spaces in old urban areas in Europe and the aging of community power grids have made the construction of private charging piles difficult and slow.
Fortunately, the EU has included charging facilities in the scope of infrastructure, and various countries have introduced policies such as subsidies, simplified approvals, and upgraded power grids to stimulate the explosive growth of private charging pile construction; coupled with the affordable price of the equipment and easy installation, it is expected to lay a solid foundation for the development of new energy vehicles in Europe.
Secondly, AEAUTO's AC EV Charger has unique advantages and is of great significance in terms of power grid operation. It can flexibly achieve "peak shaving and valley filling", cleverly balance the supply and demand of electricity, and greatly relieve the pressure on the power grid.
You should know that DC charging piles are powerful and charge quickly, which saves time for car owners. However, when running at high power, the instantaneous power load will have a considerable impact on the power grid, which can easily cause local voltage fluctuations and unstable power supply.
On the other hand, AEAUTO's AC EV Charger are adapted to ordinary household voltages, and the power is stable and moderate. Car owners can charge their cars at ease during their breaks after getting home from work, without having to look for high-power charging piles everywhere and avoid peak electricity consumption.
In addition, using the time-of-use electricity price policy and choosing the low electricity price period to store electricity for your car, not only helps the power grid to evenly distribute the power load, but also reduces the individual's charging cost, killing two birds with one stone, and providing a better solution for both car owners and power grid operations.
Finally, AEAUTO's AC EV Charger is more friendly to the battery and helps to extend the battery life. Although every battery we produce will be professionally tested to ensure normal service life, we still recommend that new energy vehicle owners give priority to slow charging when conditions permit, especially if they are not confident in their vehicle's battery management system. After all, battery damage caused by overcharging is irreversible, and the cost of replacing the battery is high.
