Realization and Design of Intelligent Charger Based on AVR MCU

It introduces the principle of the intelligent charger which takes a AVR MCU as a score. And it discusses the structure of the hardware and the design idea of the software. This charger can manage the whole course of charging. The key technology, charging-detected has been described. It also detects and adjusts the current and the voltage on the coruse of charging. It changes into floating-charge state after the charge has been finished. The whole charging bases on the curve of charging. It not only protects the battery but also achieves optimal effect. Its intelligent charge mode has effectively broken the bottleneck of conventional chargers which may cause damage to a battery in charging. The brand-new charger is in a position to extend battery cycling life and is an ideal device suited to electric bike.
