A Fast Charger Turn a low-cost SMPS into a battery charger

摘要

Here's how three ElektorWheelie fans came up with an idea for a fully automatic fast charger to keep the batteries in prime condition. This low-cost design uses an off-the-shelf switch-mode power supply coupled to an intelligent controller and can be easily adapted to charge other types of cell.rnIn 2009 we published the complete construction details of the ElektorWheelie, a single-axle, self balancing, electric powered personal transporter. It was through the German forum that the three authorsrnmade contact. Before long they had agreed that a fast charger for the ElektorWheelie's two lead acid batteries would make a useful addition to the project.
