The battery pack of the pure electric car is instead of the engine's engine to drive the car, the gearbox is slightly different, but the chassis and electrical parts are basically consistent with ordinary cars, so electric cars and traditional cars or There are a lot of similarities. Since the electric vehicle is driven by the motor, electric cars do not have oil, three filtration, belt, tightening wheels, etc., don't worry that there will be oil leakage.

Electric cars only conduct some conventional inspections of the drive battery pack and the motor, and maintain its cleaning, it can be seen that electric vehicles have great advantages over traditional cars. The proper maintenance of the vehicle is essential about safe driving and reducing vehicle maintenance costs, first, first listing the general electric vehicles and traditional vehicles similar to maintenance items: 1. Replace gearbox oil and air conditioning filter 2 each year or 20,000 kilometers 2 To replace antifreeze and brake oil every two years or 40,000 kilometers 3.

Each maintenance check chassis, lights, tires and other conventional parts should take pure electric vehicles. Different brief introductions, traditional cars, common problems , Such as replacing oil, oil filter, spark plug, valve, axle, crankshaft, connecting rod, gearbox, clutch, etc., do not appear on pure electric car, maintenance more concentrated in vehicle replacement Lossless.

The only part of the pure electric car to be replaced regularly is four tires and two rain brush slices, brake pads, etc. Regularly check the battery pack cooling system, drive motor, and power electronic devices to ensure that each component is in a good working condition. The motor electric vehicle drive system is the most critical subsystem of the electric vehicle, which is responsible for transforming the power into mechanical energy, and transmitting energy to the wheel through the transmission to drive the vehicle according to the driver's will.

Electric vehicle motor is the heart of the drive system. When the motor air quality is selected, the new energy of the drive system depends on the drive motor. Electric vehicle drive motors typically require frequent boot / parking, acceleration / deceleration, low speed and climbing, require low torque when driving at high speed, and requires large variable speed range.

Its important parameters include: motor type, rated voltage, mechanical characteristics, efficiency, dimensional parameters, reliability and cost, etc. In addition, the electric vehicle motor is configured to determine the motor-rating speed control system and the drive system can also affect the performance of the drive motor. Electric automotive motor has a simple structure, convenient maintenance, cheap.

The lead-acid battery of the battery pack is a battery that is now important in electric vehicles. The battery is not used by bad, and it is declares that the battery charging performance is good or bad for electric vehicle battery maintenance and service life and use performance. 1.

Yog li ntawd, lub roj teeb yuav tsum tau siv los tiv thaiv kom tsis txhob muaj qhov tob tob, thiab ua kom ntiav, thiab qhov xwm txheej dav dav yuav tsum tau ua: lub roj teeb yuav them qhov zoo tshaj plaws ntawm 50% -70% hauv roj teeb. 2. Therefore, the battery should prevent over-discharge, "undervoltage protection" is effective measures.

"Undervoltage protection" measures are controlled by electric vehicle controller, but because electric vehicle instruments and indicators are not controlled by controller, the electric car lock will start with electric vehicle lock, although the current is small, but If it is discharged for a long time, the battery will appear over-discharge. Yog li ntawd, koj tuaj yeem qhib nws rau lub sijhawm ntev, nws yuav tsum muab tua tam sim ntawd. 3.

Lub charger tam sim no yuav tsum tsawg dua los yog sib npaug ntawm lub charger tam sim no lees txais rau lub roj teeb. Txwv tsis pub, cov khoom siv hluav taws xob ntau dhau yuav ua rau cov dej electrolytic haus sai heev, thiab muaj qhov tshwm sim loj heev, thiab lub sijhawm ntev. nyuaj heev, yog li kev them nyiaj tiv thaiv thaum them nyiaj.

Lub charger uas tsim los ntawm cov chaw tsim khoom tsim ua kom ntseeg tau tias lub roj teeb yog overchargeable. 4, txhuas-acid roj teeb tshwj xeeb tshaj yog ntshai ntawm kev poob hluav taws xob, hluav taws xob poob 3-7 hnub, yuav raug puas tsuaj mus tas li, yog li thov kom them sai li sai tau tom qab siv lub roj teeb. Hais txog lub roj teeb mus sij hawm ntev, lub roj teeb yuav tsum tau them ib zaug txhua 15 hnub kom them cov roj teeb poob thaum lub roj teeb khaws cia.

5, electric car battery is running in high temperature season, important problems with charge. Yog li ntawd, lub caij ntuj sov yuav tsum tau txo kom ntau li ntau tau kom txo tau lub roj teeb kub, xyuas kom zoo thaum tshav kub kub dissipation, tiv thaiv kev them nyiaj tom qab raug rau lub hnub, thiab yuav tsum nyob deb ntawm lub tshav kub. Nyob rau hauv cov ntaub ntawv ntawm qhov kub tsis tshua muaj, muaj teeb meem ntawm kev them nyiaj tsis zoo thiab kev them nyiaj tsis txaus vim qhov them tsis txaus.

When low temperature, insulation and anti-freeze measures should be taken in a warm environment, which should be placed in a warm environment, which is beneficial to ensure sufficient electricity, prevent the emergence of irreversible sulfate, and extend the life of electric vehicle battery. In general, a car is in the first two years of life, as long as routine maintenance, there will be no problem. Important maintenance work requires: check the steering device, check the replacement brake skin, etc.

(Electric cars do not replace oil, three filtration, belts, tightening wheels, etc., there is no need to worry about oil leakage. ).
