For a BMS to go into sleep mode, the cell groups generally have to fall well below the LVC (Low Voltage Cutoff) point. This can happen when the battery is stored and not used for an extended period of time. In this case, the cell groups need to be individually charged directly, rather than through the BMS in series.
Typically, this detection circuit is placed in the BMS controller. Additionally, the DC charging port has an auxiliary power source, A+, which is a +12V DC power supply. In practical usage, some manufacturers may use this signal to wake up the BMS. 7. CAN Bus Wake-Up:
BMS controllers operate in two modes: Normal and Sleep. To transition from Sleep to Normal, one or more wake-up signals are required. This article summarizes common internal and external wake-up signals for BMS controllers. 1. Constant Power (KL30): The power supply and wake-up signals for the BMS are illustrated in the diagram below.
In one situation, when KL15 is powered, the VCU is initially awakened, and then the VCU, in turn, uses a hardwired signal to wake up the BMS. In another scenario, after the BMS has entered sleep mode, if the VCU detects certain faults within the vehicle, it uses a hardwired signal to wake up the BMS.
VCU Hardwire Wake-Up Signal: In some scenarios, the BMS is awakened after entering a sleep mode through the Vehicle Control Unit (VCU). In one situation, when KL15 is powered, the VCU is initially awakened, and then the VCU, in turn, uses a hardwired signal to wake up the BMS.
There are several reasons a BMS would end up in protection mode and sleep mode is basically an extended version of protection mode. For example, when a lithium-ion battery is at around 30 percent capacity and is then put under a sudden, high load, the battery cells can momentarily dip below the LVC (Low Voltage Cutoff).
Protection mode can be triggered due to any of these reasons, and sleep mode acts as an extension of protection mode. Why Does A LiFePO4 Battery Go Into Sleep Mode? When a battery management system (BMS) …
