- How many OorjaPac units can be supported by one fueling station?
A single OorjaPac Fueling Station holds two 55 gallon drums of methanol.A 55 gallon drum can supply fuel to 15 OorjaPac units that are completely out of fuel before the drum is emptied. Therefore, the OorjaPac Fueling Rig can support many OorjaPac units.
- Are there any environmental or Eco concerns in regards to the refueling station?
No, the refueling station is an NFPA 30 rated cabinet with compression fittings at all connection points. Additionally, all the couplings on the refueling station are self sealing couplers with an in-line “dry-break” coupler - in case a driver forgets to disconnect before driving away.
- Does a trickle charge do any harm to the battery? Are there any drawbacks to trickle charging?
No, a trickle charge is the best type of charge for the batteries as it does not heat the battery. The only drawback to trickle charging is time; however since the OorjaPac is mounted on and connected to the battery at all times, the time factor is not applicable.
- How many hours does the once-a-week equalization take?
It depends on multiple factors. However, if a “healthy” battery is assumed, a 510Ahr battery that has been depleted 40% SOC will take <6 hrs to complete equalization.
- What is the basis of our claim that a battery will last 50% longer with Oorja?
With the OorjaPac mounted, the battery State of Charge (SOC) remains at the optimum levels of 40%-80%; it does not experience any deep discharges which cause the lead sulfate (PbSO4) formation or crystallization thus preventing loss of active surface area; in general, more surface area, equals more capacity. The OorjaPac is an onboard trickle charger; therefore, the battery never experiences the high currents/temperatures associated with regular or rapid chargers. Additionally, the OorjaPac is programmed to automatically take the battery to 100% SOC daily and automatically equalize once a week.
Therefore, if a battery typically lasts 5 years, we can increase the life of the battery by 2.5 years.
- How do OorjaPac emissions compare to our state’s emissions?
(This varies from state to state) On a national level, the OorjaPac produces 66% less emissions than the power generated by major power plants.
- What environmental subsidies does the OorjaPac qualify for?
There are incentives at Federal, State, County and City levels. On a federal level, there is a $4500 per system ($3000 per kW) tax incentive from the Federal government according to the 2005 energy bill which is valid until Dec 31st 2016. At the State, County and city levels, additional tax incentives may or may not be available depending on location.
- Can the OorjaPac operate in freezers?
Yes, the OorjaPac can operate in freezers without any negative impact on OorjaPac performance or life. The OorjaPac has been operationally tested to below -30°F conditions.
- Will the OorjaPac impact a vehicle’s stability?
No, the vehicle remains well within its manufacturer’s specifications. The OorjaPac is only about 10% of the battery weight; with the OorjaPac installed the driver will not experience any difference in vehicle stability.
- How safe is the methanol tank in the OorjaPac?
Safety is our biggest priority; as such the system is very safe. The methanol tank is the only place that contains 100% methanol. It is double-contained with a thick outer steel box and an inner polyethylene container where the fuel is actually stored. As a third layer of protection, the systems cover acts as a barrier. A fourth safety measure -- a liquid spill sensor -- is located in the fuel tank; if it detects even the slightest amount of liquid, it will shut the OorjaPac down.
- Will battery watering still be required at the same frequency?
No, our in-house testing as well as data from our customers shows that the watering frequency can be extended 4-5 times. For example, if the “normal” watering frequency is once a week; installing the OorjaPac will shift the watering cycle to once every 4-5 weeks.
- How is battery watering accomplished with the OorjaPac installed?
We recommend installing “single-point” water kits to the batteries to optimize the watering process. However, even without the watering kit, the OorjaPac very easily “slides” out of the way for clear access to all the cells by removing just 4 hold-down screws.
- Will we go completely grid free with the OorjaPac?
Yes, with the OorjaPac installed, the vehicles can be completely independent of the grid.
