![]() ![]() Lithium batteries can be adversely affected by sustained periods with a very high SoC or very low SoC.Coordination between battery BMS and other charging equipment and loads can add further complications.Lead Acid batteries can be more tolerant of being overcharged with flooded batteries capable of periodic equalization charging. Battery cell balancing may require more advanced BMS.Battery Management System (BMS) may be required for battery cell over-voltage/under-voltage and other protections.Possible disadvantages with lithium are as follows: Lithium batteries do not need to be fully charged regularly unlike most lead-acid batteries which can build up a sulfuric acid layer at the bottom of the battery cell known as stratification. Tolerant of remaining in a Partial State of Charge (PSoC) for long periods of time may help with some off-grid systems that have autonomy issues.This can help with short-term grid-tied solar demand response More stable and less variable voltage operating range which does not surge or dip with high charge/discharge rates.High charge/discharge rate capability also known as charge acceptance is useful for quickly recharging cordless tools and EVs. ![]() High cycle lifetime used with grid-tied solar self-consumption usage with daily deep cycling.High Energy to Density and Weight Ratio for portable devices and electric vehicles.There are several advantages with Lithium batteries including the following: Morningstar Best Practices by Battery Chemistry.Custom Settings Info Pages for Battery Manufacturer/Models – Includes downloadable MSView Setup Wizard Files.However, this seems to be changing to some extent with the lowering costs and more lithium batteries becoming available. Due to the high cost of lithium batteries, they have not played a major role in stationary solar off-grid applications. More recently, the high cycle life of lithium has made it applicable with self-consumption grid-tied applications and the high current capability has made lithium a good choice for larger UPS systems. Lithium batteries have mostly been used where size and weight are important such as for small electronic devices, portable equipment, electric vehicles, and other mobile applications.
