it is considered close to full, you can terminate the charge (some 1/10C charger to start the timer, over a certain time after the end of the charge). The performance of a variety of lithium-ion batteries shown in Table 7.Table 7 (a) Type of six digits, the first two of height, the middle two for the width dimension, the latter two for the length dimension (mm). For example LIS063048, has a height of 6.7mm, a width of 29.9mm, a length of 48mm.Table 7 (b) models of four figures, the first two in diameter, with a decimal point after two of the height dimension. For example LIR2025, its diameter is 20mm, a height of 2.5mm. 1 positive temperature coefficient polymeric protective element.Lithium-ion battery protection circuit protection devices and. Lithium-ion battery charging or discharging process in the event of over-charge, over discharge or over-current, it will cause damage or reduce the life of the battery. To this end, the development of various protection components and the composition of the protection IC protection circuit. It is installed in the battery or battery pack, the battery get comprehensive protection. Below 60 ? VLR170 can provide 700mA, VLR230 can provide 900mA charge or discharge current. Two components withstand both 12V. Tyco has recently introduced VLR230 (5 × 12mm) and VLR170 (3.6 × 10mm) resettable strip protection components, it specifically for a lithium-ion battery or nickel-metal hydride battery pack for overcurrent or overtemperature protection. It is at its normal temperature, the low resistance (eg VLR230 resistance is 0.015O), when the current exceeds a threshold value or threshold temperature, the resistance rises sharply protective effect (the protective element in series with the battery circuit, some mounted in the battery). Figure 3 shows the characteristics of elements, the circuit shown in Figure 4.
