Jun 9, 2022 · Learn how to wake up a sleeping LiFePO4 battery by jumping it with another battery. This easy method gets your lithium battery out of sleep mode.
Free QuoteWhen a BMS battery goes into the sleep state, it essentially enters a low-power mode to preserve its overall health. This can happen for several reasons, including long periods of inactivity, over-discharge, or a fault within the bms battery management system itself.
Lithium batteries are equipped with a BMS to prevent overcharging and deep discharges. When a battery's voltage falls below a certain level, the BMS disconnects it to protect the internal cells, effectively putting the battery into sleep mode.
However, one key feature of lithium batteries is their built-in Battery Management System (BMS), which protects them from deep discharges. When a lithium battery's voltage drops too low, the BMS shuts the battery down to prevent damage, putting it into a kind of 'sleep' mode.
From connecting the battery to a charge from a solar panel, to warming up the battery and even connecting your sleeping battery in parallel to another LiFePO4 battery. The steps below are the safer and easier way to wake a sleeping lithium battery. Use a battery voltage tester or a multimeter to measure the voltage of your battery.
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.
Waking up a BMS battery can pose certain risks, both to the battery itself and to the individual attempting the wake-up procedure. One of the main risks is related to the low-voltage state of the battery.
