Voltage Quality Module
Duri ng an engine St op/Start cycle t he VQM (volt age qual it y module) mai ntains t he vehicle’s el ect ri cal s yst ems by s upplyinga s upport volt age around the vehicle's electroni c components during an engine res tart. This al lows crucial vehicle s ys temst o cont inue unint errupt ed when t here i s a s udden draw of amps from the bat tery.
The vehi cl e’s s t art er mot or cons umes 2kW of el ect ri cal power and can draw s everal hundred amps of current from thebatt ery during cranking. Thi s s udden draw of current causes a momentary volt age drop around al l t he vehicle ci rcuit s. Manyof the vehicle's electroni c s ys t ems are des i gned t o operat e at a nomi nal 12 volt s , so thi s s udden drop in bat tery volt agewit hout the VQM ins t al led woul d temporaril y i nt errupt servi ces such as :

Once the engi ne is runni ng a s ignal from t he ECM triggers a relay wit hi n t he VQM t o bypass the converter s t age andvolt age control is gi ven back t o t he vehi cl e's normal charging sys tem. The VQM is specified t o boost vol tage for ones econd, alt hough i n many s it uati ons i t can s upply a volt age boos t for up t o 5 seconds .
The VQM is effecti vel y a DC (direct current) converter, which convert s a variable DC input vol tage from as l ow as 6V up t oa s t abl e 12V DC out put ± 0.5V.
Rated at a nominal 180W , it can s uppl y up t o 15 amps of load at 12 vol ts . The VQM can t olerat e i ns t ant aneous s pikes upt o 300 W at ts , enough to maintai n uninterrupt ed power t o vehicle s ys tems during engine cranking.
