Wake-up ALM
A123 Systems has been diligently working to correct some rare conditions that affect series configurations of ALM modules. The conditions require a 13.8V charger to be connected to each individual battery in the event a fault condition is tripped which results in the terminals being placed in a high impedance mode to protect the battery as part of its normal mode of operation, such as (UVP) Under Voltage Protection, (OVP) Over Voltage Protection and (OTP) Over Temperature Protection. Upon connecting the charger, the battery will detect the 13.8V charger and will “wake-up” activating its terminals.
