The invention discloses a two-wheeled electric vehicle instrument capable of accurately displaying the remaining capacity of a lithium ion battery, and belongs to the technical field of electric vehicle instruments. The two-wheeled electric vehicle instrument comprises a driving load, a battery pack, an instrument panel and a communication power supply which are all assembled on a two-wheeled electric vehicle; according to the two-wheeled electric vehicle instrument capable of accurately displaying the residual electric quantity of the lithium ion battery, after being started, the instrument starts to establish communication connection with the battery immediately, a request data instruction is sent, the instrument receives and analyzes battery response data and then displays the data according to rules, and a compatible standard interface of a power supply is compatible with the standard interface. The cost for replacing the power battery type by a rider is reduced, the circuit can be accurately displayed, and the problem that the battery is mistakenly deemed to be exhausted due to voltage drop when a large load occurs is avoided.
