6 FAQs about [Energy storage charging pile loss 33 ]
How much power does a mobile charging pile use?
The power of mobile charging piles that we have developed is 7 kW so far. And there is energy loss when using mobile charging. The electricity cost of mobile charging pile for consumers is set as 1.5 yuan/kWh, and users should pay an additional 35-yuan service fee for pile delivery each time. The charging stations in the market vary a lot in size.
Why do mobile charging piles need a lot of space?
For mobile charging piles, the influence of high land cost is less significant. The reason is that fixed charging needs a parking place for each pile; the charging station must buy or rent a huge space. While a mobile charging pile is delivered to a user, it only needs a compact space for battery storage and charging.
What is the lowest electricity cost for fixed charging piles?
Therefore, the lowest electricity cost 0.4 yuan/kWh is employed for calculation for fixed charging piles, even lower than that of the residential electricity price. Table 1. Input parameters for users’ convenience and expenses.
How does a mobile charging pile work?
Specifically, as the mobile charging pile is delivered by the service supplier, t r o a d here is no longer the time that a user spends to the charging station; instead, it is the time starting from the point when the user places an order to the point when he/she receives a mobile charging pile.
Are fixed charging piles more expensive than mobile charging?
As the average utilization of fixed charging piles is about 10% nowadays, the LCOE of fixed charging piles is much more expensive than that of mobile charging. Therefore, EV drivers will pay much more if there are no more subsidies for fixed charging piles. And mobile charging can be more attractive to EV drivers.
What is a coupled PV-energy storage-charging station (PV-es-CS)?
Moreover, a coupled PV-energy storage-charging station (PV-ES-CS) is a key development target for energy in the future that can effectively combine the advantages of photovoltaic, energy storage and electric vehicle charging piles, and make full use of them .
