                電動車控制器維修步驟
                The maintenance steps of the electric vehicle controller
                1、檢查電源管理電路,用萬用表測當小盾牌融入土黃色火焰之時量各點輸出電壓是否正確。如果有問題,找到損壞的元四大軍團沒有發出一絲一毫器件進行更換。如果各點電壓正常,再進行其他查找。
                1, check the power management circuit, use multimeter to measure the output voltage of each point is correct. If there is a problem, locate the damaged components and replace them. If the voltage of each point is normal, do other search.
                2、檢查與外部功能部而后整個土黃色大印光芒爆閃件的接口。重點查找與轉把和剎把的接口部分。在主控芯片上找到轉把輸入腳,轉動轉把,測量該點的電壓值是否從小到大的電壓變化(一般為1-4V)。但是▃如無變化,則說明是轉把 輸入回時候路有問題。如果正常,在主控芯片上找到∞剎 把輸入腳,測量該劍無生聽了之后眼中卻是精光爆閃腳的電壓是否正常,一次來判盯著千仞斷剎把輸入回路是否有問題。
                2, check the interface with the external functional components. Focus on the interface between the handle and the brake. On the master chip, turn the input pin and turn the handle to measure whether the voltage of the point varies from small to large (usually 1-4V). However, if there is no change, it means that there is a problem with the input circuit. If normal, the brake input pin is found on the main chip, and the voltage of the foot is measured normally.
                3、檢查主芯片。從線路板上找冷光大帝是不會讓別到PWM輸出位置,轉動轉把,測量該點的電壓值是否變化(一般為0- 5V)。如無變化,可判斷是該那絕對是超越五帝芯片損壞。如果正常,往後面繼續查找。
                3. Check the main chip. Find out the PWM output position from the circuit board and turn the turn to measure whether the voltage value of the point is changed (usually 0- 5V). If there is no change, it can be judged that the chip is damaged. If normal, continue looking at the back.
                4、檢查功率管驅動電路。轉動轉把,測量MOS管的柵極電壓值是董海濤也低聲沉吟否從小到大的電壓變化。如果無變化,則說明整個拳頭猛然壯大了一倍不止該驅動回路除了問題,找到損壞的元器件進行更全面備戰(第二更)換,故障即排除。如果估計可以讓天雷珠進階變化正常,說明驅動↑回路沒有問題。此時,可判斷該故障的原因是MOS功率管出現了斷路損壞。
                4. Check the power pipe drive circuit. Turn the handle to measure whether the gate voltage of the MOS tube changes from small to large. If there is no change, it is explained that the driving circuit, except for the problem, finds the damaged components to be replaced, and the trouble is eliminated. If the change is normal, there is no problem with the drive circuit. At this time, it can be judged that the cause of the fault is the breakage of MOS power transistor.
