Because electric vehicles are relatively highly practical, many people like to use it as a means of transportation for commuting and picking up and dropping off children, but when buying electric vehicles, there is often no "one-step in place", and sometimes with the increase in demand for cars, the requirements for electric vehicles will also increase.
Common is to require the endurance of electric vehicles to increase, requiring the power to become stronger, if for such a demand, directly replace a new electric vehicle, and the gain is not worth the loss, the more cost-effective approach, is to replace the battery of the electric vehicle with "small for large", although such a practice is not encouraged by small connoisseurs, but there is indeed such a demand.
So, if the battery of an electric vehicle needs to be replaced by a small one, which accessories should also be replaced? This is the owner who intends to replace the need to understand, today for everyone to introduce, the common 2 ways to change the battery, what parts need to be replaced at the same time, not at the same time, will hurt the car, early to know early benefit.
The first replacement method: only increase the battery capacity
The capacity of the battery directly affects the endurance of the electric vehicle, therefore, if you just want to increase the endurance, the capacity can be "small for large", such as 48V12AH endurance of about 30 kilometers, replaced by 48V32AH capacity, the endurance can reach about 100 kilometers.
If it is only an increase in capacity, the electric vehicle needs to replace very few accessories, only need to replace the battery charger, to ensure that the charger can input the battery with a greater current, so that the charging time to maintain a large capacity does not need to be longer, you can, other electric vehicle parts do not need to be replaced.
The second replacement method: capacity and power are replaced by small to large
The first way to increase the endurance of the replacement, is more practical, relatively simple, but it can not meet the needs of all car owners, some owners need electric vehicles with stronger power, then, not only need the capacity to small for large, electric vehicles also need a larger voltage.
For example, the electric vehicle uses a 60V20AH battery, which can be increased to 72V32AH, which is not only endurance, but also has a greater improvement in power, and at this time, the replacement of parts, in addition to the charger that must be replaced, there is also a controller, and the converter needs to be replaced.
If the controller and converter, it can not match the voltage of 72V, which will form a "small horse-drawn cargo" situation, causing more serious damage to the electric vehicle, therefore, after replacing the battery, it is also necessary to replace these 2 important components.
Of course, now many electric vehicles, taking into account the replacement needs of the owner, in the configuration of the controller and converter, will set a certain range of general voltage values, such as the above figure, its general voltage of 48V to 80V, which means that the common 48V, 60V, 72V voltage, when switching between each other, it can be applied, no need to replace, very convenient.
However, small connoisseurs should remind a point, such a power to small for large, can only be converted in 60V and 72V, 48V voltage due to the new national standard electric vehicle, non-motorized vehicles, it can not change the power without authorization, otherwise the vehicle does not need the new national standard electric vehicle, will become an over-standard electric vehicle, in the license, on the road will be affected.
Summary: Finally, the small connoisseur summarizes the content shared in this article, if it is only necessary to increase the endurance, try not to replace the voltage, only choose the battery with the same voltage for replacement, so that only need to replace the charger that matches it, and if you need better power, you can upgrade the voltage, but this time not only to replace the charger, the controller of the electric vehicle, the converter should also determine whether it can match the battery of the new voltage, in addition, it is not recommended to replace other voltages with 48V, This will change the non-motorized nature of the electric vehicle, which is a violation.
