So, how do you tell the old and new of electric vehicle batteries? Next, we collected some common sense for everyone, hoping to help the consumers.
The difference between old and new batteries
When consumers purchase batteries, they must first check whether the outer packaging of the electric vehicle battery is intact, whether there is any damage or disassembly; then open the package to check the appearance of the battery, whether there are deformation, cracks, scratches, rust and leakage marks. Finally, check to see if the product logo is complete, including the manufacturer's name, product specification model, date of manufacture, trademark, etc.
The above points are related to the basic requirements of new batteries, which consumers can observe with the naked eye. In addition to these, consumers can also try it out by themselves.
Take the electric vehicle with 48 volt battery and 500 watt motor as an example. If the electric vehicle is just fully charged, if it suddenly accelerates the ride, if the power gauge needle only falls less than half a grid, it is a new battery; if the power gauge needle falls, It is a new and old battery; if the power meter pin falls 2-3 grids, it is the old battery that is quickly scrapped; if it is more than four grids, it is basically a scrapped battery.
Do not use old and new batteries together
Ms. Qin, a citizen of Hangzhou, found that her electric vehicle mileage was significantly shorter. After checking the repair shop, one of the batteries was broken, so she asked the maintenance master to change only one broken battery. The same situation has occurred.
In fact, old and new batteries can not be used together. To give a simple example, the two teams hold tug-of-war competitions. The strength of the red team's players is comparable, and the strength of the blue team's players is very different. When the game starts, the red team members cooperate with each other. Need to work hard, but the blue team, because some of the team members are too weak, but dragged the strength of the players, not only will lose the game, even the power of the players will be exhausted.
The new batteries produced by the original factory are all packaged after being assembled. If consumers mix old and new batteries, it will affect the performance of the new battery and cause the new battery to deteriorate prematurely! In addition, the electric vehicle battery will have anti-counterfeit labels when it leaves the factory, depending on whether the label is normal or not, if necessary, scratch the anti-counterfeit label password coating to verify the authenticity.
So how do you troubleshoot bad batteries? Fully charge the electric vehicle, leave it for a few hours or ride for a while, then measure its voltage at the charging plug. Regardless of the old and new batteries, if the measured is 48 volts or slightly higher, it is a normal battery; if it can only reach 46 volts or less, it means that one battery has a short circuit; if it shows 10 volts, then the whole battery of this group is it is bad.
Therefore, consumers who need to replace new batteries, ** choose the brand of good quality, good reputation in the market, so that product quality, safety and after-sales service can be guaranteed. Choose a battery with good product quality and after-sales service to ensure your travel.
Lead acid: teach you the difference between old and new batteries for electric vehicles
Battery is one of the main criteria for consumers to measure the quality of electric vehicles, and it is also one of the key factors determining the length of electric vehicles. The length of service life of a group of electric vehicles is not only related to the product quality of the battery manufacturer and the system configuration of the electric vehicle, but also has a great relationship with the consumer's use and daily maintenance. A group of batteries was replaced, and some consumers chose cheap second-hand batteries because of the price. However, according to expert advice, new batteries should be selected for safety reasons. And a new set of batteries, ranging from three to five hundred dollars, and more than one thousand yuan, consumers who need to replace new batteries naturally do not want to spend their own money.
