We ride electric cars every day, for a long time, and there are frequent failures of all kinds, especially when we ride electric cars for more than two years, from electronic components to circuits, to varying degrees of consumption. It's a lot of trouble when we're riding electric cars, and we don't know how to fix them, and we're pushing them to the shop to pay for them, so we can fix them by doing something. One of the most common malfunctions in electric cars, which learns the skills to stop while they're on their way, is that you're afraid it's half way down。
Trick one: undo the electrical vehicle controller
When we get electric cars on our bikes that can start, on our bikes that can't start, and when this type of stop-and-go failure happens, many people think at first of all about circuit failure, but we don't know which circuits are malfunctioning, so we have to use the exclusion method to rule out the control of the motor vehicle. When we open the seat behind the electric car to install the controller, first we find the retweeting line from the controller, and then the retweeting line is particularly well-recognised, and we find these three lines, thin red, thin green and thin black, which in one card are the retweeting lines. When the electric vehicle cannot be activated, open the door lock, the instrument displays normal, the switch to the connector controls turns the line red and thin green, when the controller is normal, and if the power is not properly activated, measure whether the two line red and thin greens have a 5 volt volts voltage using a one-size-fits-all meter, because some brand-made electric vehicle controllers have a flight-proof function, and if there is a 5 volt voltage, direct detection of whether the controller connects to the generator is normal. The control is also measured on a universal scale。
S. T. D.: dismantling the failure of the speed switch
When we turn the switch on the electric car controllers and turn the wires red and green, the electrics go on, we're going to get rid of the motors. Opens the dashboard of the electric car, and there are a number of retweeting wires inside the instrument, which locates the retweeting and control, where the retweeting of the switch controller turns the line red and green, and if the switch is made, the electric power is activated, then the retweeting of the electric vehicle is measured in 10,000 meters, or the detaching is done with a new electric vehicle. If the power is not properly activated at this time, then we will use a spare meter to gauge whether the fine red line and the thin green line have a 5 voltage voltage, and if there is no voltage, then the most likely failure is that the electric vehicle controller is moving on to the thin red or green middle of the line。
Strategic three: determine the failure of the electric circuit
When we switch the wires from the switch control on the electric gauge, but when we re-start the wires, which are connected to the unfailing electric cars, it doesn't work, so many people don't know how to fix it, and where it is. If that's the case, 100% of the failure is the speed of the controller in the three lines. There are short circuits in the middle of a thin black line that sometimes can not be activated, which is the reason for the failure to switch the wires to the electric vehicle and to the normal start. There are two ways to solve this failure: to find a longer copper line and to replace the short-circuit black line. Another method is to find a black line out of the electric car dashboard, and to measure the negative polar line of the electric vehicle's power using a universal meter, a fine line on the negative polar line that connects to the switchboard will solve this failure。
When we've got a bug in the electric car, many people don't know how to fix it on their own. We can do it without spending money to repair the shop. We can do it in the way and in the order of repairing the electric car, one by one, with a little more patience and care
