Low-Power-Range Chargers

Low-power-range (<1 kW) chargers recharge most Li-ion batteries in two- and three-wheeler EV. A block diagram illustrates components Littelfuse makes to help these chargers operate safely and at maximum efficiency. Available solutions include MOSFETs configured as bridge rectifiers and boost converters, microcontroller units, and gas discharge tubes for transient voltage surge suppression.
