Introduction

The DC generator system is designed and optimized to deliver the high currents at low voltages required for battery charging and operating DC loads.

No battery chargers or power supplies are required.

DC generators do not require a transfer switch. Transfer switches lower system reliability.

In prime power applications the DC generator lowers the overall cost of the system.

DC generators are more fuel-efficient. Site operators want the longest run time with the least amount of fuel on site

IDGPL’s DC generators have a current limit control to prevent the alternator from overheating and the engine from stalling during shorts or overloads. This feature is extremely important in battery charging because a battery in a low state of charge can demand more power than the generator or battery charger can manage. IDGPL’s DC generators will continues to supply power under current limit control, allowing the battery to increase its charge and drop its current demand. The AC generator uses a fuse or circuit breaker to protect against shorts and over current so the battery fails to get charged if it is overly discharged

A cost effective approach to save fuel and reduce noise for generators from 2 to 10 kW

An engine’s belt driven or direct driven fan and water pump present a considerable parasitic loss in the generators fuel efficiency. Engine manufactures typically size their fans (and water pumps) for the worst conditions: full load, hot weather, lowest engine speed, and this causes higher air velocities and pressure drops through the radiator.

The belt driven fan supplied with a 15 HP engine can consume as between 1.5 to 3 HP of the engines gross HP (equivalent to between 1.1 to 2.2 kW of power). Small increases in engine RPM can double the fan HP requirement, and this hurts the fuel efficiency of variable speed generators.

Using a large radiator minimizes the air pressure drops through the radiator, allowing the use of more efficient fans. Also with the low air velocities and low volumes of air, we need a larger radiator to compensate for lower heat exchange efficiencies.

Low air velocities and air flow rates allow fans of very small power. So instead of using 1.1 to 2.2 kW we use only 100 to 120 watts. This is a considerable fuel savings and noise reduction.

All engines use a small amount of oil over time. It gets past the piston rings and valve guide seals and is burned in the combustion chamber. A small amount escapes through the PCV system and a few drops usually managed to seep through a gasket or seal

The sump is bolted to the engine under the crankcase.It is a reservoir, or storage container, for the engine lubricating oil, and a collector for oil returning from the engine lubricating system.

The sump can be formed as a thin sheet metal pressing, and shaped to ensure that oil will return to its deepest section. The oil pickup tube and strainer are located in this deep section to ensure they stay submerged in oil, and to prevent air being drawn into the oil pump.

Some high performance vehicles have a baffle tray fitted to prevent churning of the oil by the rotation of the crankshaft.Baffles prevent oil from surging away from the pickup during cornering, braking and accelerating.

The sump’s large external surface area helps heat transfer from the oil to the outside air.

In some designs, the sump is an aluminium alloy casting with fins and ribs to assist in this heat transfer.

Lithium Ion Iron Phosphate Batteries with BMS

The 123BMS is the latest innovative solution for the lithium cell and battery pack monitoring and management.The 123BMS brings to you the complete system for charging and balancing or LiFePO4/LiFeYPO4 cells and other Lithium Ion batteries. Simple installation, easy settings, easy and reliable operation.In this fully modular system each cell is equipped with a small size circuit-board. Using only a single wire (or twisted wire) these boards are linked to the BMS Main Controller.The controller gathers all relevant data (the number of cells, cell-address, cell-voltage, cell temperature, bypass-current and total-voltage of the battery-pack) in order to control the operation of the battery pack.

The TOP reasons why to use the 123BMS

Monitoring and balancing function for each cellSmall size board installed directly at the terminals of each cellSingle wire communication. Easy to assemble the battery packExcellent pricing ratio: robust and reliable system at good priceDirect connection and management of the ELCON chargers (TC Charger models)Simple wiring of the whole system designed for EV and storage marketsFree PC based software to get the extended monitoring dash-board
