The electric scooter stopped charging, immediately shows 100% charge. This is a frequent malfunction at the beginning of the season or after the «bay» of the electric scooter. Do not rush to change the battery of the electric scooter. First you need to make a diagnosis. In most cases, everything is fine with the battery cells, the cause of the malfunction is in the BMS board.
BMS (Battery Management System) the board is responsible not only for the correct operation of the electric scooter battery, it is responsible for the safety of the electric scooter! It is she who eliminates the ignition of battery cells.
What are BMS boards?
The most simple BMS board has only 2 functions:
1. Cutting off the recharge of electric scooter battery cells.
2. Cutting off the battery discharge.
These are the simplest and cheapest BMS boards. They protect against fire only during the charging of the electric scooter. The accuracy of the parameters set for charging or discharging is not guaranteed even by the manufacturer himself. The board is universal and is installed in many devices. BMS is not protected from oxidation. Even if you have an ideal waterproofing of an electric scooter, condensation forms in the case due to the temperature difference, so the BMS will oxidize and break down quickly. They are not subject to restoration.
BMS with balancing and temperature sensor.
Functions of the BMS with balancing and temperature sensor:
1. Cutting off the recharge of the electric scooter battery cells.
2. Cutting off the deep discharge of the battery.
3. Temperature control of the electric scooter battery.
4. Balancing the battery cells.
Indicators of overcharging and deep discharge of battery cells correspond to the parameters of electric scooters. A temperature sensor is installed in the board, the temperature of the electric scooter battery is monitored constantly, during operation and in a state of charge. This significantly increases security! The BMS board balances the battery cells of the electric scooter. This increases efficiency and extends battery life. The board itself is covered with several layers of special varnish, which protects against oxidation. It serves for a long time and efficiently.
Smart BMS.
Smart BMS Functions:
1. Cutting off the recharge of electric scooter battery cells.
2. Cutting off the deep discharge of the battery.
3. Temperature control of the electric scooter battery.
4. Balancing the battery cells.
5. Manage settings.
6. Diagnostics of battery elements.
At the moment, this is the most technically advanced BMS board. The functions of battery operation adjustment and diagnostics have been added to everything necessary for a safe and long battery life of the electric scooter. The BMS board has its own Bluetooth module, through the smartphone application you can set the battery level of the electric scooter, the discharge level. Monitor the condition of each battery element.
After repairing the electric scooter, ask what kind of board was installed in the workshop for you? It’s not just curiosity, it’s your safety! With a simple BMS board, you yourself will have to take care of the absence of overheating of the battery. With smart BMS, for the correct operation of the electric scooter, it is necessary to know the name of the firmware. To check the installation of smart BMS, install the application and connect to the electric scooter. The absence of an application or connection means only one thing, you have not installed smart BMS.
In our repair shop electric scooters we will always tell you what needs to be done for a long and safe operation of your electric vehicle!
