Optional electric vehicle battery selection techniques is also important closed three electric vehicle manufacturers, good battery can greatly reduce the use of post-consumer and maintenance costs. Lead-acid batteries, and lithium-ion batteries are divided into different brands of battery price differences, and for lithium batteries, the greater the difference in different categories, a class II cell battery price comparison disparity. Ordinary naked eye is difficult to make a distinction between good and bad for the battery, and the battery has very large proportion of the price, so choose by brand battery cells can effectively avoid the bad fish in troubled waters. Days can, AMD is the battery industry listed company, is a trusted brand batteries. To avoid fakes, consumers can also choose not to dealers to buy batteries, and the choice to the battery franchise agency, so you can ensure the quality of the battery. Speaking of batteries, the quality of the charger is also very critical, many electric car fires occur mostly due to a short circuit caused by the charger. Charger not only directly affect the safety, but also has a direct effect on the battery life. Many battery life of only one year, not because of the quality of the battery itself Linyi wheeled electric car manufacturers, but consumers to choose the substandard quality of the charger. Long-term overcharge or charge less lead to shorter battery life wheeled electric vehicle manufacturers recommend products, so the selection of qualified battery charger is the key to life assurance, advised consumers to choose a high-quality battery charger, both to ensure security, but also to ensure battery life, even on the charger to spend 20 dollars, the loss of high-end choice than to charge a bad battery charger caused much more cost effective. 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 variable resistor value decreases with increasing oil pressure, and changes in the value of the variable resistor electromagnetic oil pressure gauge is also just the opposite; thermistor type electric water temperature sensor, the water temperature at 50 ℃ resistance is 220 Euro , when the water temperature is reduced to 115 ℃ 20 euro, while the water temperature thermistor electromagnetic sensor l00 ℃ when the water temperature is still high resistance wheeled electric car manufacturers, the temperature continues to rise until its resistance significantly reduced. Therefore, electric and electromagnetic electric car dashboard and supporting the use of the sensor should not be used interchangeably or replaced individually.
