Knowledge fuels change - Support energypedia!
For over 10 years, energypedia has been connecting energy experts around the world — helping them share knowledge, learn from each other, and accelerate the global energy transition.
Today, we ask for your support to keep this platform free and accessible to all.
Even a small contribution makes a big difference! If just 10–20% of our 60,000+ monthly visitors donated the equivalent of a cup of coffee — €5 — Energypedia would be fully funded for a whole year.
Is the knowledge you’ve gained through Energypedia this year worth €5 or more?
Your donation keeps the platform running, helps us create new knowledge products, and contributes directly to achieving SDG 7.
Thank you for your support, your donation, big or small, truly matters!
Energy Sources for Maintaining Battery Charging Systems (BCS)
Grid electricity is probably the cheapest of all available energy sources on a per-unit basis. In remote areas, however, the cost of connection may considerably exceed the cost of meeting local needs through systems based on renewable energy technologies (RET) .
Using available hydro power potential to charge batteries seems to be a possibility to supply energy at lowest costs in remote areas. For a brief overview please go here. This solution, however, is only applicable under restricted local conditions (i. e. existence of hydro power potential).
For detailed information please go to: MHP battery charging station - part 1, part 2, part 3.
If hydro power is not available, wind energy can be cheaper than using photovoltaics or diesel generator sets, particularly if the fuel supply is far from the user. However, a steady wind regime is required.
Solar battery charging (PV) is one comfortable but also expensive possibility to charge the battery direct in the house of the consumer.

Hybrid systems are for electricity generation in BCS are equally possible.
