How does the new electric car make it correctly? Do you understand what is the common failure of electric cars?

This is the old concept a few years ago! To divert back to the mobile phone with nickel-cadmium batteries. Deep charging is to eliminate memory effects of nickel-cadmium batteries. The first batch of mobile phones used was Ni-nickel-chromium batteries, commonly known as Big Brother! Then NiMH batteries, lithium-ion batteries did not have this concept! But many older generations, in remembering this lesson with practical related experience: The battery must be deep and deep! And carry forward the large, set on all rechargeable batteries.

So that electric cars must also be deep and deep. After half a year in use, electric cars can be properly placed every month, and it can improve the battery life. But if the new battery is deeply discharged, it is not only able to extend life, but instead of harm to the battery.

However, the first two charging time can be properly extended (not more than 12 hours) so that the battery is fully activated, and it will be normal after twice. Battery must pay attention to the battery during normal use, at least 30% of power, at this time, charging can prevent battery premature aging, capacity reduction. Deep discharge refers to riding to the first undervoltage protection.

After the protection, the voltage will rise at a while. At this time, it cannot continue to ride, and the riding is over-discharged from excessive discharge, but shortened Battery Life. The lead-acid battery is most tabooted, overcharge, overcharge can cause battery vulcanization.

The vulcanized battery is characterized by a full charge, the battery is hot, and the discharge is not, the capacity is particularly low, the internal resistance is large. Moreover, the lead-acid battery is also charged once during the storage period. Try to use it on the same day, charging the day, keep the full storage.

Electric vehicle loss is stored, some will starve to death! Now the electric car battery formula is more environmentally friendly, but it also becomes inadvertent, so electric car batteries should pay more attention to it. ! Question 2: What is the fault of electric car common circuit? There is too much fault in electric cars. It is divided into three parts of the motor, battery, and controller according to large items.

1. How to detect the battery's common fault detect the battery, how to detect the battery capacity? Directly connected to the positive and negative electrode of the battery to discharge, then voltage. The results of the measurement are as follows (1) The battery voltage is the same as the battery is not problematic.

(2) The same piece is too low to indicate that this problem has problems. (3) The four battery voltages do not show the battery voltage unbalanced, and the battery is repaired, the same as the electric pressure. Battery cable falls off, or rusted, fuse is fed to make voltage unstable.

Battery charging jack wire falls off, rust. 2. Motors often see the fault motor Hall boiled, the detection method is that the multimeter is adjusted to the diode gear, the red surface pen is connected to the Hall line negative, the black table brush, the Hall line yellow blue green line, the resistance is 4.

5, Hall No problem Anti-Hall bad. Motor water, rust, replace the bearing, replacement of magnetic steel motor rotor burns the direct replacement motor, there is no maintenance necessary. 3.

Controller common fault tram motor is very difficult to rotate is very difficult to control the problem of the controller phase line. Whether the phase line is sintering, there is no words, disconnects the three-phase line, and it is easy to turn it. It is the controller burned, and the three are broken.

It is still very heavy, it is the motor burned. The brake disconnection is turned off, and it is removed directly on the controller. The startup is not smooth, the controller starts the capacitor broken.

In short, the check line I like to check directly on the controller, put the transfer line directly to the controller, the car is still not turned, the controller is broken.
