Checklist of what a BMS (Battery Management System) should do. I start from the definition given by BUREAU VERITAS. Then I review the functionalities that will enable a BMS to fulfil its purpose.
What kind of protection have you designed in your installation to guarantee the safety of your battery, your boat and the crew? I look at it as a cascade of protection levels designed to limit the risk of an incident turning into a major catastrophe.
Not so long ago the precursors who have purchased and installed lithium batteries for off-grid applications could only rely on the manufacturers’ specifications to guide them. These batteries were designed for the Electric Vehicle market where speed of charge and ability to deliver high currents are most important. Over time, after extensive testing and many dead battery banks they have…
This article explains in simple terms: how a lithium battery functions; the factors that contribute to it’s premature aging; the steps to maximize it’s life expectancy.
Lithium batteries are the standard for Electric Vehicles and portable equipment where charge and discharge currents are important compared to the battery capacity. But for an off-grid application is the extra cost justified? What are their benefits and disadvantages when currents are much lower and performance over a long period of time is more important?
