摘要：

Two new techniques of the state of charge (SOC) estimation and battery charger are used to improve the lead-acid battery performance in a photovoltaic (PV) diesel-generator hybrid power system. The ability to estimate the SOC as a control signal is very important for system management and controllers. A new technique for SOC estimation on-line based on the pH meter probe uses is designed and implemented. The charging current must be controlled to avoid the unnecessary overcharging states, so a new battery charger has been designed based on a series pulse width modulation (PWM) switch. The PWM technique is implemented using a microcomputer as a system controller. The two new techniques improve the performance of the battery operation in PV hybrid system, increase the battery lifetime and decrease the maintenance and costs.
