BMS Board
Our BMS
The lithium battery protection system (BMS) in the battery pack is an indispensable module in the electric bicycle two wheel electric vehicle, three wheel electric vehicle, electric motorcycle, electric scooter and other products. The common BMS board is used for the battery status: such as the balance, monitoring and protection of voltage, current, temperature, etc. At the same time, the battery status information is reported to the central control system of the electric vehicle.
In addition to the conventional hardware function monitoring and protection, ARay's new intelligent BMS software protection board is embedded with battery monitoring and protection+programmable control chip. Through UART/RS485/CAN three communication methods, it connects with the upper computer or touch screen, mobile phone APP, and intelligently manages the lithium battery. The multi-directional data monitoring and safety warning of battery current and voltage provide a complete dual protection of software and hardware for the entire lithium battery system of two wheel/three wheel electric vehicles, which greatly improves the safety performance.
