At Elebia, we understand that battery issues can be frustrating, especially when they affect the performance of your hooks. Our hooks are equipped with a Battery Management System (BMS) designed to protect the batteries from overcurrent and overvoltage, ensuring the longevity and safety of your equipment. However, there are instances where the BMS may block the battery to prevent damage to the hook’s electronic components. Below, we outline common scenarios that may lead to battery blockage and how to address them.
When Does the Battery Get Blocked?
The battery can become blocked under certain conditions, including:
-Short Circuit: If the hook experiences a short circuit, the BMS will intervene to protect the internal components.
-Improper charging: If the battery is not charged correctly, the BMS may block the battery.
To unlock a blocked battery, simply connect it to the charger. This will reset the BMS protection and allow the battery to function normally again.
Hook Does Not Initialize When Battery Is Inserted
When you insert the battery into the hook, it should emit initialization acoustic signals. If you do not hear these signals, the issue may lie with the PCB not receiving the necessary electrical current. To troubleshoot, measure the voltage at the battery terminals using a multimeter. The nominal voltages are 12 V for the EVO2‑1700 battery and 24 V for the EVO‑1700 battery. If the battery indicator shows a charge but the voltage reads 0 V, it is likely blocked by the BMS.
Unlocking a BMS-Protected Battery
To unlock the battery, follow these steps:
1. Connect the battery to the charger.
2. Wait a few seconds for the BMS protection to reset.
3. Measure the battery voltage again.
If the voltage is now correct, reinsert the battery into the hook. If the hook emits the initialization signals and functions normally, both the hook and battery are operating correctly.
Possible Short Circuit in the Hook PCB
If the hook emits initialization signals initially but fails to move, and subsequent attempts yield no signals, there may be a short circuit in the hook's PCB.
Possible Motor Overcurrent or Short Circuit
In another scenario, if the hook operates initially but suddenly stops, and fails to emit initialization signals after battery removal and reinsertion, this could indicate a short circuit or an overcurrent condition in the motor.
Important Note About BMS Protection
It’s crucial to note that the BMS does not block the battery without reason. A blocked battery may signal an underlying electrical fault in the hook. Therefore, identifying the root cause of the BMS protection trigger is essential for proper maintenance and functionality.
