Industrial Battery Charger Testing
Battery Test Systems & DC Electronic Loads for Charger Testing
Industrial battery charger testing has a very wide usage range in todays world. Common applications are battery chargers for fork lifts, pallet jacks, lift trucks, electric vehicles (ev) and hybrid-electric vehicles (hev). In most cases these types of chargers and batteries are expensive, quite large and difficult to move.
NH Research Inc.’s (NHR) test solution, with capability up to 48 kW, solves this problem by utilizing DC electronic loads (Model 4700/4760 ) and a Programmable DC Source in order to emulate a battery. The benefit of emulating or eliminating a battery as part of the test set up is the fact that the emulated battery dramatically reduces testing time, provides highly repeatable test results, and creates a safer test environment. Also, preparation time, operator errors, and result variations due to battery temperature or aging, are eliminated.

Battery Test Systems & DC Electronic Loads
Battery Test Equipment
There are two types of test equipment for battery test.
The 9200 Series Battery Test System consists of bi-directional, regenerative DC power modules with voltages of 40, 120 or 600V. Capable of charge/discharge and cycle testing of 10 – 250kW module and pack-level batteries, this highly flexible system can be integrated into an existing software environment, run from a PC with NHR’s Enerchron® Test Manager or locally through a touch-panel located on the 9200 cabinet.
The High-Current DC Electronic Load (120V) 4700 Series and High-Voltage DC Electronic Load (600V) 4760 Series air-cooled dc loads can be used in applications where discharge only is needed. These loads can be controlled either through LabVIEW or NHR’s Enerchron® Test Manager.
