It’s cold and can’t run far, don’t blame the battery for now!

The weather is getting colder and colder. For some people who often ride electric cars, there is always this doubt: the battery is fully charged, and the electric car will lose two grids when it accelerates. It is no problem to go to the maintenance point to check the battery. note! People are afraid of cold in winter, so are batteries! remember! You love your battery, and the battery will give you love in return! It’s cold and can’t run far, don’t blame the battery for now! Teach you four tricks, the electric car runs 10 kilometers more! So where is the problem? In fact, if the battery test is normal, the electric vehicle will lose two bars as soon as it accelerates. Generally speaking, it is a normal phenomenon. At present, most electric vehicles use lead-acid batteries. When a chemical reaction occurs inside the lead-acid battery, the surrounding temperature will play a big role. The battery’s stored energy is proportional to the ambient temperature; when the ambient temperature drops, the battery’s energy The stored power drops. This is a problem with the principle of lead-acid batteries. Therefore, new cars may not run far. When the weather is warm, the batteries can return to normal conditions. According to related experiments, the battery capacity is based on a temperature of 25°C. For every 1°C drop in temperature, the battery capacity drops by 1%. In a low temperature environment, the battery cycle capacity is relatively low, the electrolyte viscosity increases, the chemical reaction resistance increases, and the charging time may be shortened. The charging capacity is 60%-70%, and the discharge capacity is ranging from 50% to 60%. Reduced mileage (not far away). Winter mileage calculation (70% charge multiplied by 60% discharge capacity is approximately equal to 42% summer mileage). 1. Self-discharge of the battery. The battery of an electric car is self-discharged. If you leave the car for a few days after fully charging your electric car, the power loss will decrease over time, and you will be riding at this time. The power will be lost as soon as the throttle is applied. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
