New energy vehicles are so hot, is the battery safe enough?
In recent days, the increase in rainfall has caused waterlogging in many cities. Many car owners are frightened when they go to work every day, because after the vehicle is blistered, the electronic components on the car may be damaged, and the engine may directly pull the cylinder. The new energy vehicles that are emerging now are driven by electricity, while rainwater can conduct electricity. Then the question is coming, will there be electricity leakage when the new energy vehicle is wading? What is the current development of batteries for new energy vehicles? This article will answer them one by one!
First of all, the "Safety Requirements and Test Methods for Power Batteries for Electric Vehicles" published by the AQSIQ clearly pointed out the safety indicators and test methods. The specific inspection requirements are: monomer seawater immersion, battery fully charged, immersed in 3.5% NaCL solution for 2 hours, the solution is immersed in the battery as a whole, observed for 1 hour; module seawater immersion, module fully charged, immersed in 3.5% After 2 hours of NaCL saline, the solution was submerged in the module and observed for 1 hour. This method of verification is far beyond what we encounter every day. Secondly, the batteries of electric vehicles are completely closed after leaving the factory. Many manufacturers will also do safety tests. In order to check the waterproof performance of the battery pack, they soak the battery pack in water for 24 hours, and then check the performance indicators To be tested. Therefore, external water cannot enter the battery and cause a short circuit, not to mention the battery leakage problem.
Worried about security? Let's solve the charging problem first!
In fact, when buying new energy vehicles, 4S stores will give away charging piles for free. This measure has solved the charging problem of most consumers. But the reality is that the vast majority of consumers do not have independent parking spaces, and can only charge the car by "flying the line" (that is, plug the row out of the indoor lead). A powered row is placed outdoors and a lot will be added Danger and uncertainty. The most obvious example is what to do when it rains while charging? Moreover, many manufacturers do not recommend charging with long leads. So if you want to use peace of mind, let's solve the charging problem first.
Eating carrots lightly and worrying about how to use them
All in all, the strict regulations and policies of the manufacturers and the safety tests of manufacturers have made the safety of new energy vehicle batteries have reached a very high level, and we do not have to worry too much. And now the country is also vigorously subsidizing new energy vehicles, which has also greatly promoted the development of the industry, and consumers' acceptance of it is becoming higher and higher. At this stage, new energy vehicles are very competitive, such as unlimited licenses, no refueling, cheap maintenance, very comprehensive audience range, etc., down to tens of thousands of Zhidou, EQ and other scooters, up to one million The Tesla MODELX is your choice. Of course, the premise is that you have to solve the charging problem.
