<p>A conventional charging device, in general, relates to charge the battery under the control through rated voltage method, rated current method, battery temperature rise detection method, etc. However, unless otherwises measuring the discharge capacity we are not likely to know exactly the residual power capacity the battery deposits. Under such a circumstance, the battery is often overcharged not only to waste power energy but shorten the life span of battery. The present invention relates to a close-loop charging device being thus controlled through timing measuring battery's internal resistance being provided to compare with reference value and indirectly measuring battery's saturation status whereby the user may determine to whether continue charging or not so as to avoid overcharging.</p> |
