Roborock S4, S5, S6, S6 Pure, S7, S8, Q5, Q7, Q Revo MaxV Pro & Various Models | Replacement Spare & Repair Parts: Battery BMS PCB Board

OVERVIEW

This electronic component is inside the Roborock 5200mAh/6400mAh battery (we sell the whole battery in the listing here), it is for battery repair. In fact, the wire that comes out of the battery and connects to the robot itself, comes from this component and belongs to it.

Note - this procedure is complex and requires a lot of expertise. If you don't have it, you better replace the whole battery.

The board is not original, but is compatible with an original/OEM Roboorck battery.

More about BMS:

A BMS stands for Battery Management System. It is an electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its safe operating area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, and balancing it. Here are some key functions of a BMS:

• Protection: Ensures the battery operates within safe limits by monitoring parameters like voltage, current, and temperature.
• State Monitoring: Tracks the state of charge (SOC), state of health (SOH), and other critical metrics.
• Balancing: Ensures even distribution of charge across individual cells to maximize battery life and efficiency.
• Data Reporting: Provides information about the battery's status to other systems or the user.
• Control: Manages charging and discharging processes to optimize performance and longevity.

The BMS is crucial for the safe and efficient operation of batteries, especially in applications like electric vehicles, renewable energy storage systems, and portable electronics.
