【正文】 ng the rest time after the discharge. The relationship between the battery capacity and charge time is proposed to have a logarithmic correlation. This relationship is shown below in Figure 2. Figure 2. Charge Cycle Time and Battery Capacity Relationship Charge cycle time can then be calculated as follows: 2)_(log_10?=mAinTCapacityBatteryC Where CT = chargecycle time. Individual time slices within the charge cycle can be calculated using: srestondarysedischsrestinitialsechCCCC4_sec3arg2_1argατατατατ ==== Where ∝ 1 = , ∝ 2 = , ∝ 3 = , ∝ 4 = Therefore, a 1000 mA capacity battery has cycle time of 1 second, τ charge= 980μ s, τinitial rest= 5μ s, τ discharge= 5μ s, τ secondary rest= 10μ s. A 10,000 mA battery will have twice as long charge cycle time and time slices. The Divide and Conquer Approach to Charging a HighCapacity Battery Pack Our proposed method for implementing pulsecharge in highcapacity batteries is to partition the battery pack into smaller sections (possibly already done to acmodate by the electronic requirement variations). This is shown in Figure 3. Figure 3. The Divide and Conquer Method to Charge a HighCapacity Battery Pack. A series of pulsechargers is then applied to charge these sections individually. The reasoning behind this method is that if a battery pack is prised of individual cells, the cells’ characteristics are not identical hence may not charge/discharge at a uniform rate as the pack is in used. Therefore, breaking the pack into smaller sections and charged individually with an intelligent charger allows them to be conditioned correctly and more uniformly. Charging individual sections as shown above is proposed as the better method to charge a high capacity battery pack. However, implementation of this method is more plicated and expensive than charging the pack as a whole. Additional control logic needs to be implemented to keep the chargers’ inputs and multiple load outputs to maintain efficiency. 5. Conclusion Advances in advanced battery charging technology have been numerous, including the development of the battery conditioning concepts, intelligent fast charging, and pulse charging. Pulse charging bined with intelligent control yields many advantages over conventional methods in maintaining battery capacity as well as extending battery life. This paper proposes a new divide and conquer method to charge small sections of highcapacity battery pack, which was experimentally shown to be more efficient than charging the whole battery pack simultaneously. Applications of this new battery charging method are currently being explored. Future work includes testing out the proposed methods on real highcapacity batteries such as the hybridelectric motor used in automobiles.
