Results and Discussion This research shows that the most used control method for charging and discharging lead-acid batteries in renewable energy systems with battery energy storage is that of CC–CV. However, this control method requires a long time to charge the battery.
This test procedure contains two parts: Part 1 and Part 2. Battery charger systems are to be tested using either Part 1 or Part 2, based upon the specific scopes in C and D. Note that the test procedures in Parts 1 and 2 share common reference and definition sections.
Despite the fact that constant-current–constant-voltage (CC–CV) is the most used control method for battery charging and discharging, other methods such as FLC or MPC have shown better performances.
The rate of charge or discharge, expressed in terms of the rated charge capacity (see definition) of the battery. A discharge rate of one-C draws a current (in A or mA) equal to the rated charge capacity (in Ah or mAh) and would theoretically discharge the battery in one hour.
The discharging step aimed to eliminate the remaining electric current to avoid the potential danger of explosion from a short-circuit or self-ignition of the battery when dismantled . Meanwhile, the dismantling process aimed to separate the battery components, consisting of the battery sleeve, anode, separator, and cathode sheets [3, 47]. ...
The battery discharge energy (Wh) is calculated by multiplying the voltage (V), current (A) and sample period (h) for each sample, and then summing over all sample periods until the end-of-discharge voltage is reached. IV. No-Battery Mode and Off Mode Tests These tests measure the power consumed by the charger when it is not charging a battery.
