At the Eco Products International Fair, it have been held from March 4 to 7 and then, apparently there was something quite interesting in the automotive field even there was less attention, namely the work environment friendly cars created by young generation of the Indonesian nation. Both, hybrid and electric cars was in the booth of Indonesian Institute of Sciences (LIPI)
Both cars are less attention because one of them is Kijang Super was output of Toyota in the early 1990, and another small hatchback. However, the writing on the side of the car was quite attractive to certain people. At Kijang Super of Toyota written "The 1st Electric Car Conversion." Meanwhile, one more "The 1st Elecric Hybrid Vehicle." Interestingly, if this hybrid car made in bulk, cost of production is estimated to 50 million Rupiahs.
The two cars were met by chance because most journalists waited for the winner announcement event of Toyota Eco Youth with a stage in front of the booth LIPI. Perhaps, it could have been overlooked.
According to the LIPI's Public Relations in charge at that time, Mustari, both cars were engineered by LIPI's in Bandung, in which it handles the problem of instrumentation and mechatronics.
Type series
it is certainly interesting, that as more hybrid cars, it is trend of automotive in the world today, and it appeared original work made in Indonesia. A compact hatchback seem a performance sufficiently. Unfortunately, when he was asked to detail its dimensions, Mustari said he did not have.
Just described, the car was equipped with a generator with a 160 cc engine in the rear, while the battery was in front. The function of the engine was to charge the battery. Next car is run by a battery. More precisely, hybrid cars tried to be investigated by LIPI were the type of series. That is, a car was driven by electric motors.
From the specification of the driving source explained, this car used 2-phase electric motor with a voltage of 72 volts, AC current. Maximum power could be produced by 43 PS at 7500 rpm rotation. While that was the torque of 129 Nm. The control system was 72 volt/550 amperes.
For batteries, lithium-ion was not equipped. However, the package was 72 volt/220 Ah. The car came with a charger 72V/25 ampere. According Mustari, the ability of this car had speed up to 70 km / hr.
The interior of this car was very simple and it was apparently done by those who are not experts in the field. This can be seen from the stitching interior trim, good seats, steering wheel and dashboard. Even when the trial opened and closed the door, it was not like the condition of cars sold in the market.
According Mustari, hybrid cars were done by trail and error to cost Rp 200 millions. "If it is made in bulk, the price can be 50 millions Rupiahs, compared to a quarter the price of research," he explained. Conditions were without air conditioning and entertainment equipment as well as make the driver or other passengers easy.
Further, this car was worked out by LIPI since last year and it was preferred to explore the driving system. "We try to show off, who knows there are companies who want to use, invest in making hybrid cars our expert engineering," said Mustari.
Battery
Achmad Rizal, Marcomm PT TAM, engineer graduate of ITB, when he was asked to comment about hybrid and electric cars of LIPI said about what it was personally conducted by LIPI for development is less fit. "If you want to develop the technology, try to make the battery. Development is mostly done in the company recently focusing on the battery, "he said.
Explained, components such as electric motors, control systems (electronic), and others was not a problem. " if only it was contrived battery filled with a fast, lightweight, and high energy saving abilities, certainly it will be sought not only by the car manufacturer, also by electronic gadgets," said Rizal.
On the other hand, according to Rizal, electric cars and hybrid LIPI still use regular batteries instead of lithium-ion batteries.
