ELI5: Why do batteries lose charge when they''re not being used?
A battery is stored potential energy. Energy tends to disperse due to the second law of thermodynamics. We try to stop that flow of energy so that we can harvest it when we need it, but no matter how efficient the container it will always lose some energy. (And some containers can be very efficient, for example, water towers.)

6 FAQs about [Why do energy storage charging piles charge slowly ]
How do energy storage charging piles work?
To optimize grid operations, concerning energy storage charging piles connected to the grid, the charging load of energy storage is shifted to nighttime to fill in the valley of the grid's baseline load. During peak electricity consumption periods, priority is given to using stored energy for electric vehicle charging.
Can energy storage reduce the discharge load of charging piles during peak hours?
Combining Figs. 10 and 11, it can be observed that, based on the cooperative effect of energy storage, in order to further reduce the discharge load of charging piles during peak hours, the optimized scheduling scheme transfers most of the controllable discharge load to the early morning period, thereby further reducing users' charging costs.
How long does it take to charge a charging pile?
In the charging and discharging process of the charging piles in the community, due to the inability to precisely control the charging time periods for users and charging piles, this paper divides a day into 48 time slots, with the control system utilizing a minimum charging and discharging control time of 30 min.
How to reduce charging cost for users and charging piles?
Based Eq. , to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.
How to optimize the configuration of electric vehicle charging piles?
When optimizing the configuration of electric vehicle charging piles, it’s necessary to consider the limited number of charging piles in the parking lot. We assume that the charging information can be shared with EVs in real-time to provide decisions for charging decisions and path planning. 3.11.2. Route planning
How many charging piles are there?
The demand for slow charging piles is only 18. Its total number is 30. There is a reduction of 80% compared with the 153 charging piles obtained from the charging demand forecast. Assume that the time cost of electric vehicles to queue or transfer to a new charging station is the same as the time cost of fuel vehicles.
