Introduction

What is a diesel battery charger, (DBC)? It's a small diesel engine driving a high output alternator to minimze engine horsepower and fuel consumption when compared to an AC generator with a subsequent electronic battery charger. It is also smaller and weighs less than the AC generator and electronic battery charger. Modern inverters provide AC power of a higher quality than public utilities. An AC generator almost never produces the right frequency or voltage and most often is wasting fuel running at light loads.

Seven Standard Models

There are seven standard models to choose from, covering a range of voltages and power.

The standard models are shown in the table below. The kilo-Watt rating is calculated using rated Amps and the absorption setpoint voltage.

Voltage	Rated Amps	kW	Part #	Cost ($)
12	150	2.2	DBC12-150	6,190
12	280	4.0	DBC12-280	9,950
24	75	2.2	DBC24-75	6,590
24	175	5.0	DBC24-175	9,950
24	300	8.5	DBC24-300	13,950
48	100	5.7	DBC48- 100	13,950
48	200	11.5	DBC48- 200	15,950

Every DBC comes with the watertight EnerMatic Controller. Included are the alternator and battery shunts and the battery temperature sensor. Additional relays or modules may be required to control solar panels and/or wind/hydro generators.

The watertight EnerMatic Controller uses connectors rated to IP-67 so it is ready to go into an ocean buoy, or a mountain top communications shack.

Fuel

All of the DBCs will run on petroleum diesel or good quality biodiesel. Fuel pre-heat may be required.

Cooling

The diesel battery charger can be cooled by several means:

• with a conventional radiator and engine mounted fan;
• a remote radiator with an electric fan;
• a marine heat exchanger with wet exhaust; or
• a keel cooler with dry exhaust.

Better By Design

What makes the Ample Power DBC the best diesel charger available? Compare the features and benefits against other similiar units.

• Smart Alternator Regulation with temperature compensation ...
  • Battery service life is much greater when they are charged at correct voltages for their temperature.
• Efficient large frame alternator ...
  • A large frame alternator is more efficient than a small frame unit which means that more current can be delivered for less horsepower and fuel consumption.
• Electronic alternator current limiting ...
  • Rather than attempt to match alternator output and engine horsepower with pulley ratios, electronic current limiting allows for precise setting at higher amperage output than provided by mechanical means.
• Engine power matched variable current limiting ...
  • When the engine also drives another apparatus, such as a refrigeration compressor, alternator output is reduced automatically to free up some power for the other load. The alternative, used by others, is to shut the alternator completely off. Typically, the DBC can produce 50-70% of it's output Amps while powering a second load.
• Remote radiator with EnerMatic fan control allows an effective sound enclosure with sufficient cooling. ...
• Full electric start/stop from EnerMatic Controller ...
  • Unlike other units that offer electric starting, the DBC doesn't require manual throttle control before starting, and to stop the engine.
• Automatic shutdown for low oil pressure or high temperature ...
  • Warning buzzers offered by others are fine as long as you're there to hear them, and you can get to the engine to turn it off before permanent damage occurs.
• Advanced regulator can drive two alternators ...

The Hot Water Option

While the DBCs are efficient, there is waste heat which can be used to make hot water, or heat living spaces. Distributing this heat is done with a circulating pump which is turned on and off by the EnerMatic Controller. The controller senses engine coolant temperature and turns on the pump when the engine is warm enough.

The DBC hot water system can be connected to the same coolant circuits as the passive solar panels, however great care must be taken to keep the liquid circuits full at all time.

Heating a water tank can be quickly accomplished by using an inverter to drive the AC heating element, and the DBC to circulate coolant through the coils in the tank. The inverter represents a significant load for the DBC, so not only does it provide heat via the AC element, but it also causes the engine to heat and thus provide more energy for the hot water tank.

The Hot Water Option requires the EnerMatic Controller and includes the DC circulating pump;
