Update ALM wake-up

The A123 Systems ALM 12V7 Part Numbers 400520-001 and 400520-009 when mounted in series configuration requires 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.

A123 Systems has designed new ALM 12V7 Part Numbers 400520-201 and 400520-209 which allow the charger to be placed across the entire series string (13.8V x the number of ALM’s in series) to wake up all batteries simultaneously in the event that a fault condition occurs that puts the terminals in a high impedance mode. The new Part Numbers are available now.
