The invention discloses a parking starting lithium ion battery current-limiting charging device and a vehicle, and particularly relates to the field of current-limiting circuits. Comprising a current-limiting charging circuit used for charging the parking starting lithium ion battery; the normal charging circuit is used for charging the parking starting lithium ion battery; the control module is respectively connected with the current-limiting charging circuit and the normal charging circuit; the control module is used for obtaining target battery parameters of the parking starting lithium ion battery and controlling the normal charging circuit to work to charge the parking starting lithium ion battery with first charging current when the target battery parameters meet preset conditions. And when the target battery parameter does not meet the preset condition, the current-limiting charging circuit is controlled to work to charge the parking starting lithium ion battery with a second charging current. The charging current is limited in the low-temperature or high-SOC interval, so that the problem of lithium separation of the lithium ion battery during low-temperature charging and high-SOC interval charging is solved.
