Or, more accurately, troubleshooting electrical issues when a lithium battery is being used. Over the years, Ive found that there is a great deal of mystery surrounding electrical systems on motorcycles, and as a result, parts are often replaced until the problem goes away.
Mercedes CEO Dieter Zetsche says, "The intelligence of the battery does not lie in the cell but in the complex battery system." This is reminiscent to computers in the 1970s that had big hardware but little software [1] …
BU-808a: How to Awaken a Sleeping Li-ion
From my exprience the quickest way to KILL a lithium ion pack is to keep it topped up with full charge. Bad to keep plugging in charger to restore 100 percent. Or repeatedly removing and returning device to its docking station . Bad also to unplug charger after it has ...
Lithium-ion (Li-ion) batteries are popular due to their high energy density, low self-discharge rate, and minimal memory effect. Within this category, there are variants such as lithium iron phosphate (LiFePO4), lithium nickel manganese cobalt oxide (NMC), and ...
The nail test was originally designed to replicate a cell failure caused by a piece of rogue metal that gets into the cell during production.
