What’s the real reason why electric cars don’t run far in winter?
As the temperature drops, especially in winter, many users will encounter such a problem, that is, the problem of electric bicycles not running far. So, what is the reason for this? In fact, this is a normal phenomenon, and there are four main reasons.
1. Charging in low temperature environment
First of all, everyone needs to know that battery capacity will change with temperature. According to relevant test data, the best charging temperature of the battery is 25 degrees, and every 10 degrees drop, the battery capacity will drop by 10%. This means that if the charging temperature is 0 degrees, the battery capacity will drop by 25%, that is to say, the real power of the electric bicycle will be one less battery, which also means that it will not run far. For this problem, users need to park their electric bicycles at a suitable temperature for charging, and do not charge them in an open-air low-temperature environment.
2. Battery loss
Secondly, if you don't run far in winter, there may be a battery loss problem. As the temperature drops, many users like to leave their electric bicycles at home for a long time, but in fact, the battery will be self-discharged and lose money. Once the battery loses money, the capacity will drop rapidly, causing it to run short. For this kind of problem, users need to turn off the battery switch and charge them once a week to prevent battery losses.
3. Tire pressure is too low
In addition, due to the drop in temperature, many electric bicycles will have low tire pressure. Once the tire pressure is too low, the driving resistance will increase, which will affect the endurance and cause a short run. For this kind of problem, the user needs to pump up in time to keep the tire pressure in a reasonable range.
4. Overload driving
Finally, it may be overloaded driving, causing the electric bicycle to run short. Why do you say that? Because in the overload state, the power consumption is several times that in the normal driving state, which means that the overload driving will seriously shorten the cruising range. Taking an electric bicycle with a battery life of 50km, under overload conditions, it may only have a battery life of 30km, or even lower.
In short, the short run in winter is generally caused by the above 4 reasons. For this, it is necessary to maintain a reasonable tire pressure, not overload driving, not charge in a low temperature environment, not let the battery loss, etc., to maximize the battery life of the electric bicycle.
