“…The top threshold value agreeable in NEDC driving cycle and at top and general threshold values were acceptable in highway cycle. Kim et al 62 studied experimentally an FC-battery hybrid system equipped and tested with a generator alternative for motor to recover braking energy. They conducted the experiments using NEXA power module of 1.2-kW FC hybridized with 50 Ah Ni-MH battery and reported a regeneration efficiency improved using generator is 63.8% compared with the 24.2% efficiency of regenerative braking using the motor.…”

Summary Depletion of earth's petroleum resources, greenhouse gas emissions, and global warming issues are caused by the conventional vehicles around the globe. In recent years, automotive industries focus on emerging alternative energy sources to mitigate the relying on fossil fuels so as to reduce global harmful emissions. Researchers have focused on the different aspects of hybrid and battery electric vehicles, such as energy management, regenerative braking control, and architecture of power electronics. This paper emphasizes on review of various energy management systems (EMSs) based on fuel cell hybrid electric vehicles (FCHEV) in combination with two secondary energy storage systems like batteries and ultracapacitors to provide high‐performance energy storage system. The performance of the FC–battery–ultracapacitor with various types of energy management schemes and experimental investigations is reported in this paper. This paper provides various braking control schemes to alleviate the hydrogen utilization of an FCHEV in connection with batteries and ultracapacitors and furthermore gives thorough investigation of FCHEV on their energy utilization, configuration, and EMSs developed by different analysts. This study focuses on energy allocation schemes, experimental approaches, recovery of regeneration, and EMS for next generation hybrid electric vehicles.

Summary Two electromagnetic power generators were designed and built with the purpose of creating a safe, noncarbon emitting, and long‐lasting source of energy. Prototype A has 20 coils and B has 10 coils. Each one has 2 flywheels, a second‐hand ferrite magnet that spins over the horizontal plane (lateral axis), and neodymium magnets (NdFeB). A literature review is provided covering the origins of the first direct current generators up to the most widely used contemporary alternating current power generators, comparing them with both prototypes. These were compared with each other to determine which performs better by making mathematical projections and checking them experimentally. The prototypes are based on an innovative configuration for mechanical energy conversion, which supplies power every time the system is in motion. The harvested energy has shown results—in terms of output power, power density, and specific power—which depend on several factors, such as the mechanical force induced and the period of time they remain spinning by the flywheels. The different parameters of the systems, which include connections, structure details, spinning plane, experimental results, and materials, are specified. Advantages and disadvantages are also analyzed, including some immediate real‐life applications. The designs have been improved by changing the shape of the coils and magnets as a whole to create enduring power systems.
