WHAT SHOULD I DO IF THE ELECTRIC UNICYCLE BATTERY BROKE DOWN?

Many today are planning to buy a NineBot, Inmotion, KingSong or GotWayelectric unicycle. These unique products allow you to easily and quickly enough to move around the city, but even they occasionally fail. They receive energy from the battery, and with its replacement or restoration may be associated with certain difficulties. The main problems of failure of the battery in electric vehicles.

WHAT TO DO IF THE BATTERY OF THE electric unicycle IS OUT OF THE SYSTEM?

With improper care of the device and violation of the manufacturer's recommendations, batteries can fail for several reasons:

Deep discharge (improper storage). This happens after long storage without recharging, and at low temperatures the process is accelerated;
Short circuit (aftermath of impact). This occurs as a result of the shedding of the active mass and damage to the base of the separators. The defect is fatal and causes the drive to become completely unusable;
Accelerated discharge (contact oxidation). This occurs as a result of contamination of the electrolyte or the battery itself, the defect can be eliminated in the service center.
Interrupted circuit. If this defect occurs, there is no voltage at the pole terminals. This happens as a result of the rejection of the welding contact between the batteries.
In some situations, the polarity changes as a result of a breakdown of the connection of the current rectifier, or oxidation of the battery terminals.

Due to the specifics of the device drives for electric unicycle, it is almost impossible to repair them yourself at home. After the nature of the problem is established, it is necessary to determine how the wheel can be restored to its performance — to restore it by repacking or to replace the battery.

REPLACEMENT OF CELLS IN THE ACCUMULATOR (RESTORATION).

Batteries for battery.

If the damage to the battery turned out to be insignificant, it will be much cheaper to restore its working capacity by repairing and repacking. Modern batteries consist of several elements connected in series to each other. If one of them fails, you can remove it by replacing it with a new one.

Of course, you need to understand that the new elements will allow the battery to work, but will not restore its original capacity. The battery is designed so: the weakest element determines its level of discharge. And the weakest elements are those that remained “old” after repacking.

The recovery process involves several steps:

- removal of the protective shell: carried out using a set of tools. The work must be carried out carefully so as not to damage the integrity of the elements;

- disconnection of the BMS board and cells with batteries

- pin wiring between cells and batteries

- check by the tester of each element: for the detection of unsuitable

- removal of damaged items

- cleaning: if scum or corrosion centers form on the contacts, clean the affected areas, preparing for further installation;

- repacking: new cells are installed with the same characteristics as the original ones.

- balancing: equalize the charge on each battery

- spike: with electric welding in the necessary sequence we connect into a “circuit” and solder to the BMS board

- test: check the output voltage at the battery connector (it should correspond to the parameters for the controller of the electric unicycle)

- we isolate: for its use it is necessary to restore the insulating packaging.

The best battery manufacturers are Samsung, Panasonic and LG. Their drives are distinguished by the most stable operation and are used by most of the leading manufacturers of electric unicycle and other types of self-balancing electric vehicles.

Such manufacturers as Gotwey and KingSong often choose a battery from LG or Panasonic when developing new models.

EXIT POSITION OF THE CONTROLLER IN THE BMS BATTERY.

In some situations, the cause of the problem is a malfunction of the controller (Battery Management System). It is a fee for monitoring and controlling the process of charging and discharging a one-wheel hoverboard. It also determines the current state of the drive, controls the temperature and controls the charging process. If your electric unicycle suddenly stops charging normally, the problem is most likely in the control board.

For several reasons, it is better to contact the support of a specialized service center:

BMS is a complex technical device. Even if it is susceptible to repair, special skills and knowledge will be required to restore its working capacity;
Only an experienced master can determine whether the control board can be restored, or if it needs to be replaced;
If you need to install a new BMS controller, it is important to choose the right replacement component to replace the failed one.
Only experienced specialists can carry out this work, so it is better to pre-select the service center that suits you.

IS IT POSSIBLE TO INCREASE THE BATTERY POWER DURING ITS REPLACEMENT?

This question is very controversial, and the answer to it depends on many factors, ranging from the manufacturer and ending with the operating conditions.

All monocolice electronics are designed to use batteries with certain characteristics, and an increase in power may have an unpredictable effect. If the outgoing current is too large, it can overheat the one-wheel hoverboard and cause it to break. Too weak drive on the contrary does not ensure the normal operation of the motor.

Therefore, we recommend using the advice of qualified professionals who will be able to assess the potential of your electric unicycle and correctly select a new battery for it. They will be able to determine whether it is possible to improve the performance of the electric unicycle by installing a drive with higher performance.
