Electric vehicle batteries are not durable? There may be a problem with these components!
It has been nearly 160 years since Prandtl invented the lead-acid battery. With the continuous improvement of technology, the technology of the lead-acid battery we now use has been quite mature. Limited by the chemical properties of the lead-acid battery, the battery energy There is not much room for improvement in density. Theoretically speaking, it has reached its limit. Why are lead-acid batteries less durable than in the past? In fact, it is not the reason of the battery, but the influence of these components!
The impact of the Charger
on the battery is the first. Unsuitable or inferior Charger
s can easily charge the battery. The main reason is that the current is too large or the current is unstable, lacks current protection, and cannot intelligently power off. As a result, a violent chemical reaction occurs inside the lead-acid battery, generating a lot of heat, causing the battery to swell or even be scrapped. Inferior chargers can easily catch fire and threaten human life. You must not be greedy for cheap when buying a charger, you may lose more!
Wires are like capillaries in electric vehicles, which lead electrical energy to every electrical appliance in the car body. The resistance directly affects the energy consumption of the battery, as well as the resistivity. We all know that the greater the resistance, the higher the heat generation, the same reasoning , If the body line resistance is very large, the loss of the battery itself is also large, and the service life will be reduced.
Generally, when buying an electric car, you must see the wiring of the electric car and the quality of the wire. Low-cost electric cars generally use inferior copper wires, which not only waste electricity but also damage the battery!
The controller, the controller is the brain of the electric vehicle and the distribution center of the electric current. If the controller is bad or disordered, the electric current will be unstable. The excessively high power output of the controller will cause the battery to discharge with high current or damage the controller. After that, it will be discharged stealthily, leading to battery loss, which is also an important factor leading to battery loss.
Tires, on the surface, seem to have little to do with the battery. In fact, it is not. As the only carrier in contact with the ground, the tires bear the weight of the entire car. Naturally, they are the most difficult component. The friction of the tires directly affects the power consumption of electric vehicles. , Similar to automobile fuel consumption, electric vehicle tires have too much friction, similar to snow tires and off-road tires. The batteries of these vehicles are often in a high-power state, and they wear out faster than ordinary tires!
On-board electrical appliances, in addition to conventional electrical appliances such as motors, controllers, chargers, and instrument lamps, electric vehicles are now equipped with many high-end configurations, such as seat heating, handle heating, LED long-distance lighting headlights, and high-fidelity There are many high-end equipment such as audio and even driving recorder. In fact, these appliances are very electricity-consuming, especially the LED high-brightness headlights, which are generally around 45W-60W, which is particularly expensive. If these high-end features are turned on If you do, the damage to the battery is also great, and you will find that the battery will become less and less durable!
If we want the electric car to run far and use the battery for a long time, these parts must be checked frequently. Don't change a new set of batteries or the same. After these problems are avoided, we must pay attention to the battery maintenance method. This is my next time. Share with everyone!
