This paper explores a control strategy for a Dual Active Bridge (DAB) used for the integration of removable batteries on Electric Vehicles (EVs). It uses Single Phase Shift (SPS) control at different switching frequencies to increase power and extend Zero Voltage Switching (ZVS), while it works in burst mode at low power.
The power supply system of outdoor telecom cabinet is installed in the field environment, and the installation and maintenance conditions are complex. The feasibility and convenience of installation and maintenance operations, and the personal safety of operators should be considered in the design.
The Outdoor Telecom Cabinet system includes rectifier modules, monitoring unit, power distribution units, battery packs, temperature control and other equipment, they are installed in an all in one outdoor cabinet. The all in one outdoor cabinet is divided into an equipment compartment, a battery compartment, and a wiring channel.
Battery cabinet systems are very heavy. Total weight of a loaded cabinet can exceed 6100 lbs. Use at least 3 people when unloading and setting equipment in place. It is imperative that only qualified personnel work on this system and installation, maintenance or upgrades be performed with insulated tools and equipment.
Never enclose batteries or battery cabinets in a sealed air tight room. All jewelry and watches must be removed prior to installing or servicing this system. Do not smoke or present flame near or around any battery cabinet system. Never leave a panel off or door open and unattended. 3. INSPECTION UPON RECEIPT OF GOODS
Install plastic covers onto batteries. Some covers may need to be notched for locations with bus bars and/or cables in upward orientation. Ground the battery cabinet to the main building ground. A ground stud inside the cabinet is provided for this. Refer to the UPS or charger manual for start up and operation of system.
Clearance: A minimum of four inches is required in both the front and the rear of the cabinet. This refers to obstruction of ventilation only. Clearance around cabinet sides is suggested by NEC and local codes. CAUTION! Explosion/Fire Hazard Warning: Batteries can generate potentially explosive gas (hydrogen).
