CASE STUDY OF SPRINTER VAN CAMPER CONVERSION

A Client, let’s call him Mr. T, contacted us from Texas. He had heard that there was some kind of device that would permit him to use the BOSCH alternator to power vehicle’s auxiliary roof air conditioner when driving. Mr T. felt that the engine air conditioner did not cool sufficiently to keep the entire camper comfortable when driving.

For various reasons Mr. T did not want to use a generator, the main reason being the need for frequent refueling of the generator tank. I informed him that the ADVERC Battery Management system would utilize the full power of the 150 amp BOSCH Alternator and that it would make it possible to use the alternator for this purpose as long as the total combined usage did not exceed the alternator’s output capacity.,

VEHICLE

DODGE Sprinter 2006 model with 150 amp BOSCH Alternator. Equipped with one standard VARTA start battery and one VARTA 100Ah semi-traction vented auxiliary battery mounted behind the passenger seat. Mr. T complained that the built in inverter had quit working and that he would have to go back to the dealer and get that replaced. The auxiliary battery measured only 12.1v. Mr T had bought a 2000 watt inverter at a Pilot Truck stop on his way to our place.

Results:

When idling the engine the conventionally regulated alternator could not maintain a circuit voltage that was sufficient to power the 2000 watt inverter. There was insufficient charging voltage to charge the auxiliary battery and thereby maintain a circuit voltage that would power the van’s installed inverter.

After having installed and connected the ADVERC Battery Management System the service 110v A/C cable was connected to the 2000 watt inverter. he 110 v roof A/C turned on right away and ran at HIGH without any problems. And to Mr. T’s delight the internal inverter came on after a few seconds and powered internal appliances The blowers of the vehicle’s air conditioning functioned at full power.

Mr. T was now going back to the dealer to see about getting the increased idle kit installed and the 2000watt inverter wired into the camper’s 110v shore power.

CONCLUSION AND RECOMMENDATIONS



Alternators:

Conventional alternator systems with constant voltage output do not compensate for heavy loads on the system, resulting in loss of charging current and insufficient circuit voltage to power appliances. The ADVERC System through its unique design senses and compensates for these loads and maintains alternator output at its very maximum. The ADVERC System makes it possible to utilize the BOSCH Alternators in lieu of generators.

Idling speed:

Although the amperage output when regulated by the ADVERC System is dramatically increased alternators might need higher rpm’s to properly supply electrical loads. The SPRINTER dealers cab supply increased idling speed kits. Higher idling speed is required to increase engine temperature and an oil pressure to prevent diesel fuel to wash off the lubrication from the cylinder walls.

Batteries:

It happens that vehicles are delivered from the dealers with batteries that have been sitting in storage for some time. This results in auto discharge, which was probably the cause of the low voltage of this vehicle’s auxiliary battery. As is demonstrated a conventionally regulated charging system will not restore such a battery. The ADVERC System compensates for the low voltage in this case, by maintaining the total vehicle circuit voltage at a level that will, in cases like these, permit restoring and recharging.

Voltage drops.

Any engagement of fans, lights, refrigerators, TV consoles, causes voltage drops in the circuits, resulting in impaired charging capacity in conventional alternator systems. Batteries that are insufficiently charged will deteriorate quickly. The unique design of the ADVERC System counteracts such drops in microseconds. It is harmful to run electric motors on too low voltages. The ADVERC System by maintaining the circuit voltage at proper levels, considerable extends the life of electrical motors and appliances.

Since unregulated voltage drop compensation can result in costly damages, it must be pointed out that the ADVERC System incorporates a number of safety features. The underlying principle is that batteries should be charged fully, quickly and without damage to batteries, alternators and vehicles. The ADVERC System has been tested at the Motor Industry Research Association for Electro Magnetic Compatibility to meet 95/64/EC, for use on vehicles, particularly specialist vehicles, such as ambulances and fire vehicles, (without which it cannot be fitted) though it really applies to all vehicles. For compliance any electrical equipment fitted must not impact normal running of the vehicle or cause malfunction, when it is running.

ADVERC voltage control of the alternator and battery sensing, results in 100% state of charge compared with 60%-70% using standard regulation, at a faster rate of charge and safely.

By cycling the battery voltages above and below the gassing point of the battery, to an established program developed over 12 years, and by compensating for ambient temperature variations around the batteries.

ADVERC is a controller not a booster.
