The invention discloses a charging device for a household electro-mobile. The charging device comprises a rectification module, a filtration module, a charging interface, a storage battery pack and a serial-parallel conversion module; a power grid outputs electric energy to an electro-mobile for charging through the rectification module, the filtration module and the charging interface and is connected with the storage battery pack for charging through the serial-parallel conversion module; the storage battery pack provides a charging power supply to the electro-mobile; and storage batteries in the storage battery pack are connected in parallel by the serial-parallel conversion module for charging or are connected in series to charge the electro-mobile. According to the charging device, when the storage batteries are charged, the storage batteries are connected in parallel, the storage batteries are charged without a booster module; when the electro-mobile is rapidly charged, the storage batteries are connected in series and are boost-charged to realize rapid charging of the electro-mobile; as various protection modules are adopted, the safe and stable operation of the charging device for the household electro-mobile is guaranteed; as a timing module is adopted, the timing operation of the charging device is realized, thus the charging device is convenient to use; the charging device can charge the electro-mobile rapidly; and a circuit is simple, reliable and high in stability.
