36.5 Kilometers Per Liter ( 2.7 Liters per 100 Kilometers )

The Power Jockey not only stabilizes the terminal voltage of the main battery bank, but further  augments its storage capacity using an auxiliary accumulator based on electro-chemistry of your choice and cost. This will provide larger storage of regenerative and kinetic energy thus reducing cost and emissions of combustion engine usage.

Assessment by Dr Patrick Yong who has a PHD in electrical storage systems on the Power Jockey. A scientific explanation as to how and why it works. Test was conducted on 4 Toyota hybrid models with dual 12 volt battery system. The results are as follows

1) 1998 Prius Generation 1. This vehicle was exhibiting weak main battery symptoms. It would turtle (low power) now and then and was returning around 18 kms/L. After installation of the new Power Jockey system there was a perceptible improvement in power and performance and fuel economy was now 21 kms/L. A full tank of gas previously recorded 600 kms but increased to 750 kms. This was a 25% improvement with nothing else done to the vehicle other than installation of the Power Jockey. The occasional turtle also ceased to appear.

2) 2001 Prius Generation 2. This vehicle was doing 20 kms/L. After installation it was returning 25 kms/L.

3) 2004 prius Generation 3. This vehicle was returning 21 kms/L. After installation it was returning 24 kms/L highway driving and 27 Kms/L city driving. The discrepancy here was that in city driving around 50 KPH it was able to run in electric mode alone quite easily. On the highway the petrol engine was engaged more often. Many of these model Prius are only returning 16-18 kms/L due to ageing of the HVB. We can improve it to 24 kms/L simply by installing the Power Jockey system.

4) 2004 Estima Hybrid. This vehicle was recording 10.5 kms/L city and 12 kms/L highway. The hybrid has a 2400 cc petrol engine wand when it starts up to charge the batteries fuel consumption increased. After installation of the Power Jockey we recorded 13.5 kms/L city driving and 15.8 kms/L highway. We believe we can improve highway economy to 17 kms/L as with the bigger engine the regen and inertia issues seem to cancel out and provided the vehicle with better efficiency. Results for the Estima differs from the Prius due to the size of the engine giving it better highway performance.

What this means is that the Power Jockey system can increase the fuel economy of an already very fuel efficient vehicle by 25% or more.

Below is a test done earlier last year. 

Is this the pushing the limit in fuel economy for a Hybrid? We think it is close. In a recent test on the effect of a Power Jockey on a Toyota NHW20 Prius, we managed to achieve 36.5 Kilometers per liter in city driving conditions.
