Using Solenoids to Increase Safety in Hybrid Cars
A manufacturer sought a solution for disconnecting the battery of a hybrid car during an accident, without the possibility of the battery connecting again. TLX designed a custom latching solenoid that used residual magnetism instead of a permanent magnet; meaning once the solenoid unlatched, it would not re-latch without applying power.
If a hybrid car is in a serious accident, passengers and emergency personnel risk coming in contact with the automobile’s high voltage battery. In order to eliminate the danger, a manufacturer sought a solution for disconnecting the battery during an accident, without the possibility of the battery connecting again.
The TLX Solution
TLX designed a custom latching solenoid that used residual magnetism instead of a permanent magnet; meaning once the solenoid unlatched, it would not re-latch without applying power. A pulse of power in either polarity would provide exceptional latching force without permanent magnets. The residual magnetism latching design is suitable for use in vehicle locks, latches, disconnects and safety cutout applications.
