Electric car batteries are not durable?

Date:Mar 24, 2020

It has been nearly 160 years since Prandt invented the lead-acid battery. With the continuous improvement of technology, the technology of the lead-acid battery we are using is quite mature. Due to the limitation of the chemical properties of the lead-acid battery itself, the battery energy There is not much room for density to increase. Theoretically, it has reached its limit. Why are lead-acid batteries less durable than in the past? In fact, it is not the cause of the battery, but it is affected by these parts!


The impact of the charger on the battery is the first. An unsuitable or inferior charger for charging the battery can easily damage the battery. The main reason is that the current is too large or the current is unstable, the lack of current protection, and the intelligent power-off. Leading to a severe chemical reaction inside the lead-acid battery, generating a large amount of heat, causing the battery to bulge or even be discarded, a poor-quality charger is also liable to catch fire, threatening human life and safety. You must not buy cheap chargers, you may lose more!


Electric wires are like the capillaries of an electric vehicle. They conduct electrical energy to every electrical appliance in the body. The resistance directly affects the amount of energy consumed by the battery, as well as the resistivity. We all know that the greater the resistance, the higher the heat generation. The same reason If the body line resistance is large, the battery's own loss is also large, and the service life will be reduced.


Generally, when you buy an electric car, you must pay attention to the wiring of the electric car and the quality of the wires. Low-cost electric cars generally use inferior copper wires, which not only consumes electricity but also hurts the battery!


The controller, the controller is the brain of the electric vehicle, and also the current distribution center. If the controller is not good or disordered, the current will be unstable, and the excessive power output of the controller will cause the battery to discharge or the controller to be damaged. Later, it will steal the discharge, which will cause the battery to lose power, which is also an important factor leading to battery loss.


Tires, on the surface, it seems that the tires have little to do with the battery. In fact, otherwise, the tires are the only carrier in contact with the ground and carry the weight of the whole car. They are naturally the most difficult parts. The friction of the tires directly affects the electric 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 cars are often in a high-power state, which is faster than ordinary tires!


On-board electrical appliances, in addition to conventional electrical appliances such as motors, controllers, chargers, instrument lamps, etc., electric vehicles are now equipped with many high-end configurations, such as seat heating, handle heating, LED long-distance lighting headlights, high-fidelity There are many high-level configurations such as audio, even driving recorders. In fact, these appliances are very power-consuming, especially the LED high-lighting headlights, which are generally around 45W-60W. It is particularly power-consuming. If these high-performance functions are turned on With this, the damage to the battery is also very large, and you will find that the battery will become less and less durable!


If we want an electric car to run long and the battery lasts a long time, these parts must be checked frequently. Do not change a new set of batteries or look the same. After avoiding these problems, we must also pay attention to battery maintenance methods. Share with everyone!
