Electric Rover Board turn to judge good or bad
We are talking about the Electric Rover Board before the battery ah what, and rarely introduced to turn to such a small parts, and today there is a customer asked this question, Electric Rover Board turn to judge the point of good or bad.
Turn the line three red, black negative, green signal, (there are many root) attention to more than the line, the color gap is the same as the three turn to measure the line.
In the case of correct wiring, open the power lock, the omnipotent table transferred to the measured DC voltage file 20v black pen then negative, red pen connected to the controller to supply the positive and negative pole whether there is about 5v voltage.
If the voltage is normal, and then move the red pen to the signal line, measured whether there is about 1v voltage (positive) is a good turn slowly turn in the end, look at the universal table on the voltage from 1v or so slowly rose to 4.2v or so if some of this turn is good is being put.
If there is no voltage or voltage between the plus or minus voltage of the measuring switch, as long as the voltage is about 1v or 2v, then the connection between the handle and the controller should be disconnected directly from the controller to measure the positive and negative Voltage, if the measured voltage is about 5v or so is the turn of the bad change handle.
When we Electric Rover Board when no electricity will think of charging, in fact, we do not really understand the way electric vehicles, the following by our Linyi Electric Rover Board manufacturers to tell you about the three common Electric Rover Board charging method.
1. Constant current charging, is the process of charging the current is constant. If it is more than a series of batteries in series, generally choose this way the charging method, the current in the charging process is very small, so the charging time is longer, our family is generally used in this way.
2. Fast charge, this charging method allows the Electric Rover Board to quickly complete the charge. In a short time, this way can be sent to the battery within a large current pulse, the entire charging process is actually the battery in the repeated charge and discharge, this way can make the Electric Rover Board charging quickly completed, but because of this way the charging current And the voltage is not fixed, so the battery has a certain impact.
3. Constant voltage charging, refers to the charging process, the voltage to maintain a constant amount. At the beginning of the charge, the battery resistance is very small, the charging current is very large, and after charging for some time, the battery internal resistance increases, charging the charging current becomes smaller, this charging is relatively fast way.
Electric Rover Boards in our lives can be seen everywhere, and now the weather is getting warmer, and choose to ride Electric Rover Boards are more and more people, today we Shandong Electric Rover Board manufacturers to universal about the awareness of electric vehicles fire.
1. To always check the electric bicycle circuit plugs, to prevent contact is not strong caused by contact point ignition, fever; to avoid the aging of the line, wear and cause short circuit, the occurrence of string accidents.
2. Electric vehicles in the course of normal use, failure to choose a professional maintenance agencies or personnel, do not unauthorized removal of electrical protection devices to ensure that electrical circuits and protective devices in good condition.
3. Electric bicycle battery will run out of the combustible gas, so the charge must not be in a narrow, sealed environment, should be carried out in the outdoors, or remove the battery alone charge.
4. When charging to select the appropriate line, line laying should be fixed installation, to install short circuit and leakage protection device.
5. Electric Rover Board charging must be away from flammable items, can not charge too long, charging time is too long, the charger overheating easily lead to fire, the charge should be in accordance with the provisions of the instructions to charge, charging time in principle not more than 10 Hours.
6. In the process of starting the electric bike, climbing should pedal help to prevent the start current is too large, the machine for a long time overload work, causing the motor coil, lines, batteries and governor overheating damage, and even brewed Into a disaster. To try to avoid in the rain, water sections of the road to prevent the motor into the water, charging short-circuit fire.
As long as we rational use of electric vehicles is not a fire like this kind of thing, mainly to remind you to use Electric Rover Boards, charging time can put safety first.
