How to distinguish between electric vehicle batteries?marine battery wholesale

　　1. During the trial process, the electric vehicle detects the advantages and disadvantages of the battery, install the battery that is just full of power to the electric vehicle, start the electric vehicle power supply, and suddenly accelerates the electric vehicle during driving to observe the change of the power meter pointer:

　　(1) The pointer of the electric meter in the process of accelerating the cycling process is less than half the case, then it is determined that the battery is brand new or better;

　　(2) In the process of accelerating the pointer of the electrical table in the cycling process, 1 block or even 2 blocks of the electric meter will be judged that the battery is an old battery or poor quality;

　　(3) The pointer of the electric volume table in the process of accelerating the ride is 3 cells or even 4 grids, and it is determined that the battery is a product that fakes new batteries after the battery is repaired. The quality is extremely poor.

　　2. Determine the new and old battery through the outside packaging of the battery:

　　(1) View the phenomenon of damage or disassembly of the outer packaging;

　　(2) Check the appearance of the battery itself, and observe whether there is a rusty traces of the wiring header of scratches and positive and negative electrodes;

　　(3) Check whether there are anti -counterfeiting labels on the battery shell, whether the production date is relatively long, whether the manufacturer's relevant information logo is complete, and whether the writing is clear and complete. If there is a case of 1 point and 1 point in the outer packaging of the battery, consider that the battery is an old battery, and the quality may have problems. 3. Look at the new and old of the battery in appearance:

　　In fact, this is a good judgment. Generally, you can judge if you get your hands. You can judge whether there are traces of grinding flowers and scratching, and then see if there is rust on the positive and negative metal parts of the battery.

　　4. Use professional measurement voltage tools to determine whether the battery has internal short circuit (bad battery): riding for a while or after charging the charging car, measure the voltage at the charging plug, and measure the 48 volts. Or a slightly higher point is normal battery (regardless of new and old). If it can only reach 46 volts or below, it means that one battery has a short circuit (48 volt vehicles have four batteries in total, and each group is connected to 12 volts from 6 2 volt batteries), showing that 10 volts are bad batteries.

　　Pay attention to the use of electric vehicle batteries:

　　1. The battery should be installed firmly on the electric vehicle to prevent vibration damage during the cycling.

　　2. Frequently remove the dust and dirt on the battery cap, and keep the battery dry and clean to prevent the battery from discharging itself.

　　3. It must not allow the battery to be in a state of insufficient power for a long time, and develop a good habit of charging the battery every night.

　　4. When the electric bicycle is started, start with a pedal help to prevent the battery from being discharged too large and damage the battery.

　　5. When riding, be careful not to let the battery discharge. Excessive discharge can easily cause serious loss of battery battery, thereby greatly shortening its service life. Electric bicycles are generally equipped with voltage protection functions. When the battery electric volume display has only one display light, the battery should be charged immediately to avoid the battery discharge.
