We find that insufficient public charging piles would significantly limit the sales of electric vehicles, in particular when the public charging piles are built up for specific users or in developed regions where private parking spaces are limited.
... The popularity of charging piles can improve the adoption rate of electric vehicles . Travel anxiety caused by insufficient charging points or occupancy of electric vehicle parking spaces are factors that hinder the development of electric vehicles.
In this paper, it is assumed that the construction costs of the CS is proportional to the number of charging piles with a proportion coefficient , then, (6) The EVs end costs mainly include charging costs, driving costs, and waiting time costs as shown in Eq. (8).
According to the changes in average power of new public DC charging piles over the years (Fig. 5.5), the high-power charging piles with 120 kW and above was proliferating, with a proportion of 24.4%, up 4.7 percentage points over 2017, indicating a momentum towards higher power.
According to the statistics of China Electric Vehicle Charging Infrastructure Promotion Alliance (hereinafter referred to as “EVCIPA”) (Fig. 5.1), by the end of 2022, the number of charging infrastructure in China reached 5.209 million. Stimulated by the NEV market, the market demand for charging piles also kept growing swiftly.
In Wu and Yang's study, the authors explored the impact of insufficient public charging piles on EV sales in China. The study revealed that the lack of charging infrastructure had a negative effect on EV sales and improving its availability could promote EV adoption .

Multiply the battery capacity in amp-hours (Ah) by the battery voltage to calculate watt hours (Wh). Formula: Battery capacity Watt-hours = Battery capacity Ah × Battery voltage . Energy is equal to amp-hours multiplied by volts. Converting battery amp hours to watt-hours will give an idea of how much actual energy your battery can store or deliver. For example,A. The formula for this conversion is straightforward: mAh = (Wh × 1000) / V, where V is the voltage. For example, a battery rated at 2 Wh with a voltage of 5V would yield 400 mAh. [pdf]
To convert from energy to electrical charge, use the formula below in conjunction with the voltage. Q (mAh) = E (Wh) × 1,000 V (V) Thus, the charge in milliamp-hours is equal to the watt-hours times 1,000, then divided by the voltage. You can also convert mAh to Wh using a similar formula. For example, let’s convert 10 Wh at 12 V to mAh.
To convert milliampere-hours (mAh) to watt-hours (Wh). you need to know the voltage (V) of the battery. The formula to convert mAh to Wh is: Wh=mAh×Volts/1000 Assuming a common voltage of 3.7V, which is typical for lithium-ion batteries.
The formula to convert mAh to watts is: Watts=mAh×Volts/1000 For these calculations, let's assume a common voltage of 3.7V, which is typical for lithium-ion batteries. Below is a table showing the conversion of various mAh values to watts. sorted from smallest to largest. assuming a voltage of 3.7V. To convert 5000 mAh to watts at 3.7V:
Assuming a common voltage of 3.7V, which is typical for lithium-ion batteries. Below is a table showing the conversion of various mAh values to Wh. sorted from smallest to largest. assuming a voltage of 3.7V. To convert 10000 mAh to Wh at 3.7V: Wh=10000×3.7/1000=37 Wh To convert 20000 mAh to Wh at 3.7V: Wh=20000×3.7/1000=74 Wh
To convert 20000 mAh to Wh, you must know the battery voltage. Let us suppose that the lithium battery is 12V. Wh = mAh × V ÷ 1000 = 20000mAh × 12 ÷ 1000 = 240Wh. Similarly, let us suppose the battery voltage is 12V. The watt-hour will be: Wh = mAh × V ÷ 1000 = 10,000 × 12 ÷ 1000 = 120Wh. Why Wh is important for power stations?
Formula: Watt-Hour = Milliamp-Hour × Volts ÷ 1000 Abbreviated Formula: Wh = mAh×V÷1000 For example, if you have a 2500mAh battery rated at 3.7V, the power is 2500mAh3.7V / 1000 = 9.25Wh. The following is the conversion table of lithium battery voltage 3.7V milliampere-hour (mAh) to watt-hour (Wh), ranging from 1mAh to 50000mah:
