The invention relates to a brake energy recovery tester, in particular to a brake energy recovery synthetic tester having an anti-lock brake system (ABS), comprising a main motor and an auxiliary motor as main components, a brake with a ABS brake function and a generator which are serially connected, wherein the main and the auxiliary motors provide kinetic energy for the tester, the brake systemcontaining an ABS provides a friction brake torque and the generator provides a regenerated brake torque, which can independently realize brake or be combined to realize brake. In brake, the generator converts and stores part kinetic energy into electricity in a battery unit to recover brake energy. The tester can independently process ABS control system test and research. The brake energy recovery tester can be used as a brake energy recovery test platform to provide a test basis for improving the recovery efficiency and reliability of a brake energy recovery system.
