Independent Laboratory Tested : We believe in quality and put safety as the company’s top priority which is why EZ-Stab has been sent through to internationally renowned laboratory testing company - Intertek Testing Services for heat and stress tests. EZ-Stab is made to withstand extreme temperature in the robust engine compartment. THEORY : The car/vehicle charging system has been the same for decades. Nothing much has been done to the basic operation of the car battery charging system. For all commercially available vehicles, the output of the alternator is regulated by an IC regulator, which charges the battery all the time and maintains the battery at about 90% before fully charged. This is a continuous drain of at least 1-2kW, or more, of the useful power from the flywheel of the engine, regardless of the driver's demand or road condition. If the engine is not properly tuned, such loading can be most obvious and annoying during idling. In fact, the larger a battery is used in a car, a larger amount of energy may be required to charge the battery depending on its state of charge. The spikes and loadings on the battery affect the ECU operation. Also, the regulator IC in the alternator has limited response speed. All these result in a fluctuating voltage that cannot be cured by brute force, such as adding capacitors at the B+ 12V supply rail. (The output voltage is controlled by the IC pumping current into the excitation winding of the alternator. The performance of this IC has a direct relationship of output voltage stability. The fundamental solution is to optimize the whole battery charging system, improves the dynamic responses of the charging IC, increase the rate of change of field winding current to maintain optimal operation. And under certain operating conditions, balance the charging system such that the alternator no longer forces energy into the battery. Hence, at least 1-2kW of useful power is saved from the engine. With the loading removed, the engine will appear to be livelier, responsive, and the useful power can be transferred to the wheels. Also, with the load removed, the engine RPM is more stable and hence a more stable voltage is observed. Ez-stab provides the benefits of a balanced charging system, giving a much more stable voltage and yet reduces loading on the engine. In the near future, Ez-stab will be designed into an active control closed loop battery charging system with intelligent control/communication with the ECU. Sounds overkill, but it is an area, which many performance car designers overlooked. We have addressed this problem and had filed a patent in Singapore, soon in USA and Japan. While many perform extensive modifications such as exhaust or engine porting to gain a few horsepower; such benefits may be easily achieved thru an Ez-stab in the system with no sacrifice of vehicle comfort and vehicle warranty. Ez-stab also protects the battery and ECU for repeated heavy usage within service life. Download White Paper here.
