The balanced hypercube BHn plays an essential role in large-scale parallel and distributed computing systems. With the increasing probability of edge faults in large-scale networks and the widespread appli-cations of Hamiltonian paths and cycles, it is especially essential to study the fault tolerance of networks in the presence of Hamiltonian paths and cycles. However, existing researches on edge faults ignore that it is almost impossible for all faulty edges to be concentrated in a certain dimension. Thus, the fault tolerance performance of interconnection networks is severely underestimated. This paper focuses on three measures, t-partition-edge fault-tolerant Hamiltonian, t-partition-edge fault-tolerant Hamiltonian laceable, and t-partition-edge fault-tolerant strongly Hamiltonian laceable, and utilizes these measures to explore the existence of Hamiltonian paths and cycles in balanced hypercubes with exponentially faulty edges. We show that the BHn is 2n-1-partition-edge fault-tolerant Hamiltonian laceable, 2n-1-partition-edge fault-tolerant Hamiltonian, and (2n-1 - 1)-partition-edge fault-tolerant strongly Hamiltonian lace -able for n >= 2. Comparison results show the partitioned fault model can provide the exponential fault tolerance as the value of the dimension n grows.
