Energy Storage and Charging Techniques — Lesson 2

This lesson covers the importance of energy storage, especially in the context of renewable energy sources like solar and wind. It explains why storage has become a crucial topic of discussion, primarily due to the uncontrollable nature of renewable energy generation. The lesson also delves into the concept of grid load shedding and how it was used to manage supply and demand. It further discusses the emergence of batteries as a viable storage technique and the role of large batteries in renewable energy. The lesson also provides an in-depth understanding of different types of chargers, their efficiency, cost, and protection features. For instance, it explains the difference between on-board and off-board chargers, and the concept of level 1, 2, and 3 chargers.
