The invention relates to a tramcar redundant super capacitor control method. According to the tramcar redundant super capacitor control method of the invention, a plurality of groups of super capacitor modules are adopted; each group of super capacitor modules comprises a plurality of super capacitors with the same electric quantity; the plurality of super capacitors are connected in parallel. Thecontrol method comprises the following steps of: setting conditions for switching on and switching off the plurality of super capacitors; judging the operation conditions of a tramcar, enabling the operation conditions of the tramcar to comprise pull-in charging, driving power supply and braking energy recovery; and according to the conditions for switching on and switching off and the operationworking condition of the tramcar, completing pull-in charging, driving power supply and braking energy recovery of the super capacitors. According to the tramcar redundant super capacitor control method of the invention, the super capacitors are redundantly arranged; according to the operation conditions of the tramcar and the operation states of the super-capacitor, when a super-capacitors breaksdown, the switching on and switching off of the redundant super-capacitors and cooperative control between the super-capacitors are achieved, the operation reliability and safety of the tramcar are improved, and a guarantee is provided for the stable operation of the tramcar.
