Abstract:
Nowadays, the electric vehicles uses is increased, both for private and public transportation. The electric vehicles increasing is supported by the battery technology innovation. A reliable, inexpensive and large capacity of the battery are created but less attend to battery instrument to review the real battery performance. This paper are discussion a new method in performance test of electric vehicle battery using water rheostat to review the real battery performance. The water rheostat are consist of two set aluminum electrode plate. To increase the current discharge value is done by added water to soak the electrode plate. The data logger collected the voltage, and discharge current of times. The data analysis indicated this water rheostat dummy load have a good performance to instrumented the battery performance. The finding of this paper is: 1. The discharge current are inversely proportional with the battery terminal voltage. 2. On the discharge current value is 2.17 Ampere in
voltage 83.64 volt, the water resistivity is 2,698.06 Ohm-meters and than go down to 73.87 Ohm-meters on the voltage value 46.00 Volt and the discharge current 43.53 Ampere. 3. The discharge current a inversely with the area of electrode. 4. The water resistivity are linear function to the resistance of water rheostat. 5. Water rheostat with two sets of electrodes dimensions of 35 x 36 centimeters can be use as a dummy load of up to 2.3 KW in a voltage of 66 Volt DC.
