"Hybrid electric vehicle banyak dikembangkan di negara maju karena memiliki keunggulan yakni dapat menghemat pemakaian bahan bakar hingga dua kali lipat. Kendaraan hibrida adalah kendaraan yang memiliki dua atau lebih sistem propulsi, umumnya adalah penggerak berbahan bakar minyak bumi/sel bahan bakar dan sistem pengerak elektrik. Dalam riset ini telah dilakukan perancangan dan pengujian prototipe kontrol traksi kendaraan hibrida berpenggerak kombinasi serial-paralel mesin bensin berdaya 6,54 kW dan motor listrik 0,5kW. Pengunaan transmisi CVT (continous variable transmission) dan penggerak bertenaga listrik brushless terintegrasi sebagai motor dan generator serta melekat pada masingmasing roda belakang memperhalus perpindahan daya ketika beroperasi. Sistem pengisian baterai kendaraan ini berasal dari tiga buah sumber pengisian dengan dua buah jalur tegangan yakni altenator berkapasitas pengisian 12 V / 7 Ah, sistem power take off berupa alternator tambahan yang digerakkan motor bakar untuk mengatasi kekurangan pengisian empat buah baterai disusun seri dengan kapasitas 48 V/ 32 Ah dan sistem regenerative berasal dari kedua motor listrik pada saat kendaran bekerja menggunakan motor bakar maupun pada saat pengereman. Pengujian regenerative dari motor listrik menghasilkan daya sebesar 199,44 W pada putaran 737 RPM dan pada pengujian jalan mode hibrida dapat menghemat pemakaian bahan bakar hingga 80%.

Hybrid electric vehicle developed in many developed countries because it has the advantage that can save fuel consumption more than doubled. Hybrid electric vehicles have two or more propulsion systems, generally is driven by internal combustion engine / fuel cell and electric motor. In this research design and testing of a prototype hybrid electric vehicle traction control having a serialparallel configuration by combining of gasoline engine power 6,54 kW and 0,5 kW electric motor. The use of transmission CVT (continuous variable transmission) and electric-powered drive brushless motor and generator are integrated as well as attached to each rear wheel is refined the displacement power when operating.

Vehicle battery charging system is derived from three sources of charge with two lines namely voltage altenator with charging capacity of 12 V / 7 Ah, the power take-off in the form of additional motor driven alternator to overcome the deficiency charging of four batteries in series connection with a capacity of 48 V / 32 Ah and regenerative system comes from two electric motors at work using a motor vehicle fuel or when braking. Tests of the regenerative electric motor to produce power equal to 199,44 W at 737 rpm and for test drive result on Hybrid mode has reduced consumtion of fuel up to 80%."

"Hybrid Electric Vehicle banyak dikembangkan di negara maju karena memiliki konsumsi bahan bakar yang lebih baik dibanding kendaraan bensin. Pada umumnya, kendaraan hibrida ,yang memiliki dua atau lebih sistem propulsi, memiliki penggerak berbahan bakar minyak bumi dan sistem penggerak elektrik. Dalam riset ini dilakukan perancangan dan pengujian prototype kendaraan hibrida berbahan bakar compressed natural gas (CNG) dan sistem penggerak elektrik dengan kombinasi series - parallel mesin bensin berdaya 81 kW dan motor listrik 10 kW yang bertujuan sebagai system konversi untuk kendaraan jenis MPV. Mesin bensin ditambahkan converter kit CNG yang memiliki kapasitas 15 LSP (liter setara premium), sedangkan penggerak elektrik dengan 6 buah baterai lead ? acid dihubungkan secara parallel dengan spesifikasi 12V 200 Ah per baterai. Dari hasil perhitungan secara teoritis, didapat bahwa konsumsi bahan bakar kendaraan hibrida hasil rancangan mencapai 17.43 km/L.

Hybrid Electric Vehicle developed in many developed country because of its better fuel consumption compared to gasoline vehicle. In general, hybrid vehicles, which have two or more propulsion systems, have a gasoline fueled propulsion and electric propulsion system. In this research design and testing of a prototype hybrid electric vehicle with compressed natural gas (CNG) and electric propulsion system with a combination of series - parallel gasoline fueled engine with 81 kW power and a 10 kW electric motor that is intended as a conversion system for MPV type vehicles.

Gasoline engine added CNG converter kits which have a capacity of 15 GLE (Gasoline Liter Equivalent), while the electric drive with 6 pieces of lead acid battery connected in parallel with a specification of 12V 200 Ah per battery. From the result of theoretical calculation, it?s found that the fuel consumption of designed hybrid electric vehicles reached 17.43 km/L."
