Abstract
The design of a portable multifunctional charger is presented in this paper. The charger supports two charging modes of 220 V alternating current and 12 V DC. The 12 V lead–acid battery is used to support AC 220 V output, DC 12 and 5 V output. The maximum power point tracking and battery charging curves are controlled to extend the life of the product and improve the performance of the product. Bluetooth can be connected to the mobile phone or pad to control the battery output and monitor the battery state. The design can be used in the field of home tourism.
