These maintenance of electric cars can be done

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.

Prin urmare, bateria trebuie folosită pentru a preveni descărcarea în adâncime și pentru a fi superficială, iar situația generală ar trebui făcută: bateria se va încărca cel mai bine la 50% -70% în baterie. 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. Prin urmare, îl puteți debloca pentru o lungă perioadă de timp, ar trebui să fie oprit imediat. 3.

Curentul de încărcare trebuie să fie mai mic sau egal cu curentul de încărcare acceptabil pentru baterie. În caz contrar, excesul de curent care este supraîncărcat va face ca apa electrolitică să se consume prea repede și există un fenomen grav de precizie, iar timpul este lung. Foarte dificil, astfel încât încărcarea este împiedicată la încărcare.

Încărcătorul produs de producătorul oficial asigură că bateria este supraîncărcabilă. 4, bateriile plumb-acid se tem în special de pierderea energiei electrice, pierderea bateriei de energie electrică 3-7 zile, vor fi deteriorate permanent, așa că vă rugăm să încărcați cât mai curând posibil după ce bateria este utilizată. În ceea ce privește bateria pe termen lung, bateria trebuie încărcată o dată la 15 zile pentru a compensa pierderea bateriei atunci când bateria este depozitată.

5, electric car battery is running in high temperature season, important problems with charge. Prin urmare, vara trebuie redusă cât mai mult posibil pentru a reduce temperatura bateriei, a asigura o bună disipare a căldurii, a preveni încărcarea după expunerea la soare și ar trebui să stea departe de sursa de căldură. În cazul temperaturii scăzute, există o problemă de încărcare slabă și încărcare insuficientă din cauza încărcării insuficiente.

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. ).
