To charge a lithium-ion battery safely, follow the basic algorithm: charge at a constant current (0.2 C to 0.7 C depending on the manufacturer) until the battery reaches 4.2 Vpc (volts per cell). Then, hold the voltage at 4.2 volts until the charge current has dropped to 10% of the initial charge rate.
The aim of this research is to provide an ptimal charge current of lithium ion batt ry, by which the theoretically fastest charging speed without lithium deposition is able to be reached. In other words, a maximal acceptable charge current of lithium ion battery is proposed.
Overall, it takes 3426 s (57.1 min), which is theoretically the fastest charging time without lithium deposition, to fully charge the battery. This result is successful as it is able to support the optimal charge current theory presented previously, providing a general principle for fast charging of lithium ion battery.
To charge a lithium ion, lithium polymer, or lithium iron phosphate battery, follow the basic algorithm of charging at a constant current (0.2 C to 0.7 C depending on the manufacturer) until the battery reaches 4.2 Vpc (volts per cell). Then, hold the voltage at 4.2 volts until the charge current has dropped to 10% of the initial charge rate. The termination condition is the drop in charge current to 10%.

Let’s break it down: Battery charging current, measured in amperes (A), is the flow of electric current into a battery during charging. It’s crucial for determining the speed and efficiency of your 48V battery charging process. The charging current directly influences how quickly your battery charges.
2 · The average charge current is 1.3 A and the peak charge current of 1.7 A. If Rwire is 200 mΩ, then the average power lost in the wires is 0.26 W and the peak power lost is 0.34 W.
