This is a charger circuit for both NiCd and NiMh Batteries.When the Battery voltage is low it is charged with the usual constant current source in the normal way. But when the battery voltage increases, the charging current will become pulsed. A completly fully charged battery only requires short flashes to maintain its charge and terminal voltage.[more]
Batwatch is a simple monitor for a solar panel battery charger, using an Atmel ATtiny13V. It periodically measures the charge current and battery voltage, and shows them by blinking two LEDs.The circuit can shows the voltage and current visually, by blinking a red and green LED.[more]
This is a universal solar powered charger with minimal electronic knowledge and even less money. You make it out of one of those cheap universal car adapters and you can still use it as such afterwords. You can even change the panel you use whenever you want.[more]
This project utilizes a PIC microcontroller to monitor battery voltage and control a solid state relay, turning it ON for a time period when battery voltage falls below an adjustable low voltage set point and OFF if it exceeds an adjustable high voltage set point.The circuit is extremely useful in alternative energy applications such as wind or solar, which experience long periods of calm or clouds when no power is generated to feed the battery array.[more]
SIMPLE-VOLT ย�is a tiny, light-weight R/C Battery Voltage Monitor using a PIC microcontroller.The Simple-Volt automatically detects the number of LiPo cells connected (assume charged pack) and continually monitors the battery voltage and compares it to the preset cutoff/warning voltage corresponding to the number of detected LiPo cells.[more]
