I don’t know since when, the streets and alleys have long been full of outdoor 48V electric moped, which also shows that electric mopeds have become the first short-distance travel scooter. And electric mopeds are a kind of consumables and have a certain service life, so electric moped maintenance has also become a relatively common thing.

The core components of an outdoor 48V electric moped are a battery, a motor, and a controller. These three components are equivalent to the human heart, muscles, and brain, but the difference is that the core components of an electric moped have a certain lifespan, especially the battery. The life of the battery is relatively short, only a fixed number of cycles, and it will be scrapped after the number of cycles is reached. Therefore, an electric car may need to replace the battery several times. When replacing the battery, many car owners have raised such a question, if my electric car battery is 48V, can I replace it with a 60V or 72V battery? Is there any safety hazard if it is replaced? JianShe would talk about these questions in this article.

Can electric moped batteries be pressurized?

Common electric mopeds on the market now have batteries of 48V, 60V, and 72V. These batteries also have corresponding types of electric mopeds. For example, 48V corresponds to usually an electric bicycle, 60V corresponds to an electric moped, and 72V corresponds to an electric moped. It's an electric motorcycle. Then a car owner asked Kankan, if my electric car battery is 48V, can I replace it with a higher voltage battery?

It is theoretically possible to replace the battery but not the motor, because the high voltage can also drive the original motor. However, many maintenance masters do not recommend this operation, mainly for the following reasons.

The cost of adding voltage of electric moped is relatively high

As mentioned above, the core components of an electric moped are batteries, motors, and controllers, so can an electric moped run? How fast can you run? It is not one part that works, but the result of the joint efforts of three parts. For example, only the motor and the battery, the electric moped cannot run normally, and the controller must coordinate in the middle to achieve acceleration and deceleration.

Therefore, if you want to replace a battery with a larger voltage or pressurize the battery, you must replace the appropriate controller. Therefore, the replacement cost includes the battery and the controller, which is still a lot.

Problems existing in electric mopeds after pressurization

As mentioned above, electric moped batteries can theoretically be pressurized, but why do most maintenance masters not recommend doing this? That is because the battery of the electric moped will have a certain impact on the electric moped after being pressurized, which cannot be ignored.

The first point is the effect on the motor. Although it is said that increasing the voltage will not affect the operation of the motor, the higher voltage will cause the motor to generate more heat during operation, and the high temperature will also cause the motor to demagnetize. Therefore, after a period of time, you will find that after replacing the battery, not only the power will not increase, but it will decrease.

The second point is security risks. Choosing a battery with a larger voltage means that during the operation of the electric moped, the overall wiring harness of the electric moped will generate more heat, which has a great potential safety hazard.

It is relatively common to replace the battery of an electric moped, but one principle must be followed, that is, what is the battery specification of the original electric moped, and the specification of the battery is to be selected. The motor is also replaced together, and the cost is not low.
