Electric car battery is not durable? Maybe there is something wrong with these parts!

It has been nearly 160 years since Prandtl invented the lead-acid battery. With the continuous improvement of the technology, the technology of the lead-acid battery we use now is quite mature. Due to the limitation of the chemical properties of the lead-acid battery itself, the space for improving the energy density of the battery is not large. Theoretically, it has reached the limit, and why the current lead-acid battery is not resistant to the past Did you use it? In fact, it is not the battery, but by the impact of these components! The influence of chargers on batteries is the first. Unsuitable or inferior chargers charge batteries, which can easily damage batteries. The main reason is that the current is too large or unstable, lack of current protection, unable to cut off the power intelligently, resulting in violent chemical reaction inside lead-acid batteries, generating a lot of heat, causing battery bulge, even scrap, inferior chargers It is also easy to catch fire, threatening people's lives. Purchase charger must not be greedy for cheap, maybe your loss will be greater! Wires are like the capillaries of electric vehicles, which lead the electric energy to every electric appliance on the body. The resistance directly affects the energy consumption of the battery, as well as the resistance coefficient. We all know that the greater the resistance, the higher the heat output. In the same way, if the circuit resistance of the body is large, the battery itself will lose a lot of energy and the service life will be reduced. Generally, when buying electric vehicles, we must see clearly the wiring situation and the quality of the wires. The low-cost electric vehicles generally use inferior copper wire, which not only consumes electricity but also damages the battery! Controller, controller is the brain of electric vehicle, is also the distribution center of current. If the controller is not good or in disorder, the current will be unstable. If the controller's power output is too high, the battery will discharge with large current or the controller will be damaged, and the battery will be discharged secretly, which is also an important factor leading to battery loss. The tire, on the surface, seems to have little to do with the battery. In fact, as the only carrier contacting the ground, the tire carries the weight of the whole vehicle, which is naturally the hardest part. The friction of the tire directly affects the power consumption of the electric vehicle. It is similar to the fuel consumption of the car. The friction of the electric vehicle tire is too large, which is similar to the snow tire and off-road tire. The battery of these cars is often at a high level The state of power, than the use of ordinary tire loss faster! 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, hi fi audio, and even dash cam. In fact, these electrical appliances are very expensive, especially LED high brightness lighting headlights Generally, it's about 45w-60w, which costs electricity. If these high configuration functions are all on, the damage to the battery is also great. You will find that the battery will become more and more durable! If we want the electric car to run far and use the battery for a long time, we must check these parts frequently. Don't replace a new set of batteries or keep them as they are. After these problems are avoided, we should pay attention to the battery maintenance methods. I'll share this next time!
