It is on the choice of installer or buyer to go with PWM or MPPT as both technologies can be used to regulate the charging of Li-ion batteries. MPPT ( Maximum Power Point Tracking) charge controller for lifepo4: This is highly efficient but costly. PWM (Pulse width modulation) charge controller for lifepo4: This is less efficient but fairly cheap. Solar charge controllers are mainly of two types: Also, it regulates the flow of charge from the battery to the load connected. A charge controller regulates the flow of charge from the solar panel to the battery. Solar charge controller: Electricity generated from solar panels is always at different voltage and current levels, depending on the weather conditions and time of the day. Li-ion battery charges in phases which can be seen in the graph below: Lithium ion Charge Graph The liquid electrolyte is present in most Li-ion batteries and some have polymer (gel) electrolyte to carry charge between anode and cathode. In these batteries, the cathode is made up of lithium metal oxide and the anode of porous carbon. Electrons are freed from anode undergoing oxidation to conduct current during discharge, cathode gains electrons in the same process undergoing reduction. These batteries should not be exposed to water as they are highly reactive to them.Įnergy is stored in lithium ions which migrate from cathode to anode in rechargeable lithium ion battery. To protect the battery from thermal runaway, lithium ion battery needs circuitry built-in the battery pack, otherwise, it may catch fire or explode. Per watt, lithium ion batteries are costlier than lead-acid batteries. High cost and safety are two limiting factors of lithium ion batteries. These have high cell voltage, fast charging, and low self-discharge, and a good lifetime when deep cycled. Lithium-ion battery : One-third of the global battery market is captured by lithium-ion technology because of its high density and lightweight. What is Lithium-ion solar charge controller?Ī charge controller which regulates the charging of a lithium-ion battery is a lithium battery solar charge controller.
