Abstract

The vacuum or cleaning robot is getting popular because of the extensive features and the effectiveness for floor cleaning. A daily routine can be done to clear the floor without human involvement.

The battery management system (BMS) including battery charging, analog front end, and gauging are critical parts of the vacuum robots’ power. This application note compares the charging designs from the application requirements, technical challenges, design integration, and some of the features that simplify the vacuum robot designs and improve the customer experience.
