9) How to correctly use the electric car dashboard electric car is almost universal in China within the instrument as the basic components of electric cars, how much you know how to properly use? 5, sensor performance electric and electromagnetic instruments different. A variable resistive sensor type electric fuel gauge, the resistance increases with decreasing oil tank plane, while the resistance value changes electromagnetic fuel gauge variable resistive sensors are opposite; electric heating oil pressure gauge sensor thermistor type electric water temperature sensor, water temperature 50 ℃; the variable resistance decreases with increasing direct hydraulic closed small tricycle, and variable resistance change of electromagnetic oil pressure gauge is also just the opposite Linyi small resistance value of 220 Euro closed tricycles, 115 ℃ when the water temperature is reduced to 20 euro, while the electromagnetic water temperature thermistor sensor resistance value is still high in a small enclosed tricycle supply water temperature of l00 ℃, the temperature continues to rise until the resistance value significantly reduced. Therefore, electric and electromagnetic electric car dashboard and supporting the use of the sensor should not be used interchangeably or replaced individually. Charging an electric car, new car purchases, due to the factory, transportation, storage will take some time, it may make the battery power is low, please charge before use. 2. Check the charge of the rated input voltage and supply voltage are the same. 3, the battery can be charged directly in the car, but you must turn off the power switch, you can also come to the right place to remove the charge indoors. 4, first charging electrical output of the plug and socket connection after charging the battery properly (see figure), and then plug the charger connected to 220V AC power. (Note: Do not connect the charger to correct the negative output) 5, then the power indicator on the charger and charging red light, indicating that the power is switched on.
