Nothing is interesting from the "Electric Car Conversion" on display at the JCC held by LIPI (Indonesian Institutes of Science) and it was disclosed to reporters yesterday at the Center for Electrical Power and Mechatronics located in Bandung at once given the chance to try it. However, the car is the Toyota Kijang Super production early 1990. In fact, when trying to run around LIPI Bandung, it needed extra energy to rotate the wheel of time turn.
Operating Costs
Nevertheless, there are actually noble goal. Namely, make an old car with a body that is still good but the engine is often fussy and wasteful of materials gasoline (already confirmed cause of pollution), it can be used again. In fact, it could make operational costs much cheaper and friendly enverintoment. Even the maintenance costs are also lower. "The electric car is no longer using a lubricant such as motor fuel," said Ir Abdul Hapid.
Hence, initially, Hapid want to try the project on public transportation in Bandung. But leaders in LIPI did not allow. Understandably, it was due to the huge cost of considerable research. The Car belong to this LIPI, according to Hapid record to decrease for spending around 250 million rupiahs.
Nevertheless, based on the added value is obtained, the operational costs of the old car so much cheaper. it is Exemplified, for fuel consumption Used Car 8 km / liter. It Means that each mile by using premium, spend fuel costs per km Rp 562.5 (Rp 4,500 / 8). Excluding to mention other costs, such as engine oil and so forth.
it is also Added for more information, the cost of electrical energy consumption is highly dependent on the source. Because the rates charged by PLN (State-owned Electric Company) in each house is different, for example 450 VA, 900 VA or 1300 VA. Hapid give rough calculation, to 1 kW can be used for 4 km with electricity costs Rp 1000/kW. More precisely, the operational cost per km of electric cars only Rp 250.
The Cost of Batteries
At used car now relying on pure electric power (100 cent) or that, the original engine was removed and replaced by 2-phase electric motor that works on 96 volt voltage. However, manual transmission is still used to make this vehicle go forward, reverse, and neutral.
As a source of battery power use 16 pieces, each 6 volts. According Hapid, special batteries is purchased from abroad at a price of Rp 1.2 million per unit. The ability of an electric motor purchased the United States, it is 52 PS for 6500 rpm with a maximum rotation.
Therefore, the cost of conversion is quite expensive. For the battery itself (cells with black tin) spent Rp 19.2 million. Excluding to the motor, control systems, chargers, inverters and so forth. Therefore, even if it is applied to public vehicles, such as public transportation, the LIPI hope the support from the Government.
Performance
Operation is very simple electric car. To move forward, the stick transmission will be shifted into gear 1. As for the retreat, it will be the retreated position. When tested on the hill, the motor power is large enough.
it Claims that LIPI's electric car is able to speed up 120 km and for once the battery is able to create a distance of 75 km. it is Charging the battery at home takes 6-8 hours. It is of course less than ideal or suited to the needs of car users daily with the distance is generally 150 km. Except when it is in office in the available places, it will be charging.
Actually, electrical energy efficiency could be even higher if the vehicles used are lighter and smaller. The system is also much simpler. For example, it can be installing an electric motor directly on the axle or directly on the wheel.
it is Backward and forward movement of vehicle by changing the direction of motor rotation and using a stick that is more simple and easy to operate. In fact, also equipped with power steering that uses electricity.
Of the prototypes that have been contrived, it was concluded, a trip that must be taken LIPI researchers to realize the ideals of pure, reduce pollution in the city, is still very long and winding. Except when there are willing to support! But who?
