The utility model relates to the technical field of
lithium battery systems, in particular to an industrial vehicle
lithium battery quick charging
system, which comprises a first
battery pack, a second
battery pack and a
relay group, and during discharging, the
relay group can enable the first
battery pack and the second battery pack to be connected in parallel; and during charging work, the
relay group can enable the first battery pack and the second battery pack to be connected in series. After series connection, the total
voltage of the
system is improved, and a charging power supply with a higher
voltage level can be connected, so that higher charging power is obtained under the same charging current, the charging time is remarkably shortened, and the requirements of frequent charging and high-efficiency energy
complementation of vehicles are met.
