Solar Rechargeable LiFePO4 Battery
Introduction
A significant advantage of lithium over lead-acid batteries is that they do not suffer from deficit cycling. Essentially, this is when the batteries cannot be fully charged before being discharged again the next day. This is a very big problem with lead-acid batteries and can promote significant plate degradation if repeatedly cycled in this manner. LiFePO4 batteries do not need to be fully charged regularly. In fact, it's possible to slightly improve overall life expectancy with a slight partial charge instead of a full charge.
Efficiency is a very important factor when designing solar electric systems. The round-trip efficiency (from full to dead and back to full) of the average lead acid battery is about 80%. Other chemistries can be even worse. The round-trip energy efficiency of a Lithium Iron Phosphate battery is upwards of 95-98%. This alone is a significant improvement for systems starved of solar power during winter, the fuel savings from generator charging can be tremendous. The absorption charge stage of lead-acid batteries is particularly inefficient, resulting in efficiencies of 50% or even less. Considering lithium batteries do not absorption charge, the charge time from completely discharged to completely full can be as little as two hours. It's also important to note that a lithium battery can undergo a nearly complete discharge as rated without significant adverse effects. It is, however, important to make sure the individual cells do not over discharge. This is the job of the integrated Battery Management System (BMS).
