The invention discloses a tramcar lithium titanate battery system which comprises a battery box, an electrical box and a liquid cooling system, a positive electrode and a negative electrode of the battery box are connected to a B + connector X11 and a B-connector X12 of the electrical box through a B + connector X1 and a B-connector X2 respectively, the B + connector X11 enters the electrical box and then is directly divided into two positive electrode branches with pre-charging, and the B + connector X12 is directly divided into two negative electrode branches with pre-charging. The DC1 + connector X5 and the DC2 + connector X6 are respectively connected to the electrical cabinet; after entering the electrical box, the B-connector X12 passes through the main negative fuse FU3 and the main negative contactor KM2 and then is divided into two negative branches through the copper bar to reach the DC1-connector X7 and the DC2-connector X8; a DC1 + connector X5 and a DC1-connector X7 form a first group of output and are connected with a traction box DCU1; a DC < 2 + > connector X6 and a DC < 2-> connector X8 form a second group of output and are connected with a traction box DCU2; the whole vehicle CAN bus of the traction box DCU1 and the whole vehicle CAN bus of the traction box DCU2 are jointly connected to a whole vehicle communication X13 and finally connected with a battery management system BMS in the battery box and a connector X19 of the liquid cooling unit. The battery system is high in integration level, small in size and low in cost.
