摘要： An engine includes at least one piston, a rotatable crankshaft, a starter motor, a lithium-ion battery, and a charging system. The rotatable crankshaft is coupled to the at least one piston. The starter motor is configured to selectively initiate rotation of the crankshaft. The lithium-ion battery is in electrical communication with the starter motor and has at least one cell. The charging system is powered by motion of at least one component of the engine. The charging system provides energy to the lithium-ion battery to charge the lithium-ion battery. The engine has a starting condition, a running condition, and a stopping condition. The charging system continuously applies a voltage potential to the at least one cell while the engine is in a running condition.

摘要： A starter battery system for an air cooled engine rated at less than 50 horsepower. The system includes four lithium iron phosphate cells and a charging circuit configured to be powered by rotation of an air cooled engine. A voltage developed by the charging circuit is applied to the four lithium iron phosphate cells without battery management circuitry provided between the charging circuitry and the four lithium iron phosphate cells.
An engine which includes at least one piston, a rotatable crankshaft coupled to the at least one piston, a starter motor configured to selectively initiate rotation of the crankshaft, a lithium-ion battery in electrical communication with the starter motor, the lithium-ion battery having at least one cell, and a charging system configured to be powered by motion of at least one component of the engine. The charging system is configured to continuously apply a voltage potential to the at least one cell while the engine is in a running condition.
