Now that we understand the need of giving EV batteries a second life, let’s check where is the problem, because there is always a problem, otherwise, what engineers are for? The first and main problem is that the cells that are manufactured for the EVs are different from the ones manufactured for the stationary storage …
In a series of articles, I am going to share my research on second life batteries. This is the first article. What are second life batteries? To reply to this question, I must start from the beginning. Obviously. Lithium batteries are being widely used for two main applications: Both markets are growing and competing for …
First approach using Python to estimate the payback of a hybrid system. It is based on the feasibility study of a solar system to power an oil pump in a GCC country. Context Based on the available data, the Diesel Generator is consuming 2% of the tank every day. The tank capacity is of 5000 …

Context I am presenting an alternative solution to a telecom company to power it’s off-grid towers. The sites are working 24 hours a day, with an average load demand of 2.75 kW. They are currently running with a DG of 16.2 kW, with an estimation consumption of 11 255 liters. (The consumption estimation is based …
When I started working with storage, the need for a good understanding of the different types of batteries became imperative. With time I managed to know and compare the different chemistries, but I lacked a method to choose between them. That is why I decided to propose a simple ranking comparing the different chemistries & …
