| Abstract: | Li battery have the good features of small size, high power density, no memory effect, long cycle life, high voltage and low self-discharge. Recent years, it is the preferred battery in handheld terminals. Its charging circuitry is distinctly different from NiCd, NiMH and Lead Acid battery. There are three methods can be used to charge Li battery: switch, linear and pulse. Each method has its advantages and disadvantages. The selection of charging method is based on the cost, space and efficiency. This text will detail the charging techniques and some charging schemes for Li battery in handheld terminals. |
