How to charge electric cars most economically

< class="p" style="">Compared with fuel vehicles, the charging cost of pure electric vehicles is indeed much cheaper than refueling. However, as the old saying goes, "If you can't eat well and wear well, you can't be poor, but if you can't plan well, you will be poor." In fact, there are still many tips to save money on charging. For example: Is the parking fee in the parking lot where the charging station is located expensive? When charging at a public charging station, does the charging fee apply to the peak and valley electricity price? Although these are small amounts of money, after accumulating a little, it may be a considerable expense. Today, Sichuan Yingteli's editor will introduce to you some ways to save money when charging.

< class="p" style=""> What does our electricity bill consist of?

< class="p" style="">In fact, in the daily charging of pure electric vehicles, our final "charging fee" may be composed of three parts: electricity fee, service fee and parking fee. The first two fees are basically incurred when charging at a public charging station, while the parking fee depends on whether the location of the charging station charges it.

< class="p" style="">Electricity charges are also divided into two charging modes: one is to charge only a single electricity price for 24 hours, and the other is to charge at the peak and valley electricity price. The charging price will be relatively low during a certain period of time, and the charging price will be relatively high during the peak period of electricity consumption. Service fees are basically charged at any public charging station of any operator. At present, the national service fee collection standard is about 0.8 yuan/kWh. Parking fees will increase your charging costs to a certain extent according to the charging standards of different parking lots. So when we charge, if we can charge in a free parking lot during the period when the valley electricity price is implemented, we can spend the least money to charge the most electricity. How can this be achieved? Let us introduce some methods to find free parking lots and how to calculate peak and valley electricity prices.

< class="p" style="">◆ Free parking is hard to find? The next app will solve it

< class="p" style="">Now it is winter, the temperature of the power battery is relatively low, which will make the fast charging time much longer than in summer. If it takes one hour to charge in summer, charging in winter, especially when the power battery temperature is not high, may take you two hours or even more even if you choose the fast charging method. In this way, parking fees may increase your charging costs. If you charge in a parking lot with a charge standard of 10 yuan/hour, the parking fee you pay may catch up with half of the charging fee.

< class="p" style="">At this time, an example of technology changing life appeared. When we open some charging apps, we will find that there is an additional option in the filter conditions - free parking. When we light up this filter condition, we can find charging stations that do not charge parking fees from the map. And some of these apps have a scan code payment function. Today's electric car owners have basically bid farewell to the era of "traveling around the world with a bunch of cards on them." There is also a little trick, that is, when fast charging, it is best not to wait until the battery is fully charged before ending the charging. You can end the charging and leave when the SOC (power battery power) of the power battery reaches 80% or 90%. Because at this time, the BMS (battery management system) will issue a command to reduce the charging current of the charging pile a lot and enter the trickle charging mode. This is mainly to protect the power battery from the impact of large currents when the power is high and affect its service life. If you insist on charging the SOC to 100%, it is not impossible, but the time spent on charging 10% to 20% of the power is much longer than the charging time in non-trickle mode. If you're at a charging station with a high parking fee, it's not worth it.

< class="p" style="">Therefore, when charging on a fast charging pile, if it enters trickle mode, you can completely stop charging. First, you can save parking fees. Second, you can better extend the service life of the power battery. Third, you can save a lot of time and do what you like.

< class="p" style="">◆ Choosing the right time to charge is equivalent to a discount on electricity bills

< class="p" style="">Friends who often use public charging piles to charge their cars outside must know that charging costs may differ by 50% at different time periods. Especially for charging piles of the State Grid, basically all charging stations in urban areas (taking Beijing as an example) implement peak and valley electricity price charging standards.

< class="p" style="">So if we choose to charge during off-peak hours, for example, charging 40 kWh each time, we may save 24.38 yuan compared to peak hours. If we charge twice a week, we should be able to save 195 yuan a month; then we should be able to save 2,340 yuan a year. Of course, the more you charge, the greater the difference. Over time, won't your car cost go up?

◆ Self-sufficiency

Parking fees and service fees actually account for a large proportion of the charging fee. Is there any way to save money fundamentally? In fact, it is very simple. Install a home charging pile in your own parking space. The price of a home charging pile ranges from 3,000 to 7,000 yuan. The installation is not difficult. When you get home from work every day, charge the car and it will be fully charged when you go to work the next day. Moreover, a large part of the time for charging at night is the off-peak period, and the electricity bill will be much cheaper!

Summary of the full text:

< class="p" style="">With the increasing popularity of electric vehicles, the construction of charging facilities will continue to improve. However, charging at different charging stations and at different times may cause your charging costs to vary greatly, so it is important to plan well before charging. For example, choosing a charging station with cheaper electricity or charging at a time when the electricity fee is lower will reduce a lot of charging costs; if conditions permit, installing a charging pile in your own parking space can save a lot of expenses. In general, if you choose the most cost-effective way to feed your pure electric vehicle, it is indeed very cost-effective compared to the cost of refueling.
