“…Packed high fidelity images are stored in memory device such as SD card. What's more, considering the system is used outdoor and unattended, we select the combination of Nimh solar rechargeable battery [1] and the storage battery as the power system, which is controlled by voltage threshold switching chip, XC61FN454. The system relies mainly on solar-power and storage battery works as its supplement.…”

Aiming at the present vacancy of wireless monitoring system in the domestic nature reserve, this paper puts forward a design of portable observation system. Using the passive infrared sensor to detect wild animals and poachers in the natural protection zone, it can photograph, videotape and send pictures to users' mobile phone and mailbox through the GPRS network to alert their caution. The seamless switch mode of Nimh solar rechargeable battery and the storage battery can provide guarantee for this system to normally operate in the wild. In order to ensure the characteristic of real-time monitoring, the TRON real-time operating system with negligible starting time and the NT series microprocessor NT96211 of high-performance are adopted. The design of the system takes account of the environment and cost, it can provide a proper monitoring platform for each nature reserve and wild animal breeding model base, and offer a new model of automation and informational construction for the nature reserve.

“…Traditional terminal voltage based method (U) [146], voltage diversion (△U) and impedance scheme can be impotent at the risk of overcharging or undercharging with a tremendously changing charging current. Voltage change threshold and differential battery temperature based control algorithm [147], and the -△U approach (magnitude and slope of voltage as a function of time) [135] have been utilized in charging full state termination for the NiMH and NiCd battery, respectively. To capture the MPP more precisely, the nonlinear behavior of the battery will be modeled before algorithm establishment [135].…”

Mobile electronic devices such as MP3, mobile phones, and wearable or implanted medical devices have already or will soon become a necessity in peoples' lives. However, the further development of these devices is restricted not only by the inconvenient charging process of the power module, but also by the soaring prices of fossil fuel and its downstream chain of electricity manipulation. In view of the huge amount of solar energy fueling the world biochemically and thermally, a carry-on electricity harvester embedded in portable devices is emerging as a most noteworthy research area and engineering practice for a cost efficient solution. Such a parasitic problem is intrinsic in the next generation portable devices. This paper is dedicated to presenting an overview of the photovoltaic strategy in the chain as a reference for researchers and practitioners committed to solving the problem.

“…For the reason of the presence of high ripple in charging current, the battery storage systems need a charging circuit for reducing the ripple and extending the battery life. Several charging circuits have been proposed in literature like linear regulators and switching regulators [13][14][15][16]. Constant voltage and constant current charging are the usual batteries charging techniques.…”

This paper presents a novel unity power factor fuzzy battery charger conception based on Ultra Sparse Matrix Rectifier (USMR). The advantages of the proposed converter are low harmonic distortion in absorbed currents and nearly unity power factor over a wide operating output power range. Its circuit has only three switching components and low-energy conversion loss. This reduces the cost and enhances the system's efficiency for high voltage battery. Thus, the proposed fuzzy logic controller improves the line power quality and delivers admissible output power to the battery.Experimental results based on a 24-V battery charger are proposed to validate the proposed approach and to demonstrate its performance. The stability and performance of the battery charger is then verified by the constant current (CC) and constant voltage (CV) charge. The fuzzy control and space vector modulation (SVM) algorithms are implemented with the Digital Signal Processor (DSP).
