Charging Equipment, Mobile (CEM).
Abstract
This report covers the design, fabrication, test, and operation of the Charging Equipment, Mobile (CEM) which provides a mobile battery charging capability to field units. The design and fabrication was performed in-house at the U.S. Army Engineering Topographic Laboratories to support the Long Range Position-determining System (LRPDS). The CEM has been used specifically to recharge BB-451/U, silver-zinc batteries used with LRPDS backpackable ground units. However, the dialable voltage cutoff in the battery charger will permit recharge of silver-cadmium and lead-acid batteries, among others. The equipment was used extensively in the field tests of the LRPDS for charging BB-451/U batteries at 2.25 amperes with a cutoff at 32 volts. Although activation of the BB-451/U batteries is a slow and painstaking operation, nine batteries were easily and reliably recharged at one time. Besides the operational tests, a safety evaluation and a road test were made by the U.S. Army Test and Evaluation Command. No unusual hazards were found, and there was no evidence of physical damage after runs over the Munson Road at the Aberdeen Proving Ground. (Author)
