In this series of articles we will discuss the options you can have in your battery charger. You can check out these options for choosing your desired battery charging solution.

Special Ground Bus

This is an appropriately sized ground bus bar mounted inside the battery charger to allow customers to tie ground connections inside the charger to the external system ground. The ground bus bar allows for several customer connections.

Padlock Hasp

In those applications where the customer wants to control the access to the internal components of the battery charger, Manufacturer can provide a padlock hasp on the door of the enclosure. The customer can use their own lock to secure access to the charger from unauthorized personnel.

Glyptol Dip

Used in areas where there is very high humidity to protect the transformers from moisture and salt air. It is also known as Tropicalization. This process treats the transformer with a fungus resistant dip after the transformers have been through the standard class H dip and bake process.

Conformal Coating

A process applied to circuit boards to protect against moisture, dust and temperature extremes. The electrical insulation coating provides a level of protection to the electronics when they are used in a harsh environment such as a tropical location or mounted inside another outdoor enclosure.

Equalize Fan Control Relay

Used to ensure the exhaust fan in a battery room is operating when the charger is in the equalize mode. Two sets of form C contacts are wired to a terminal strip inside the charger. The customer wires the exhaust fan control to the terminal strip. When the charger is placed in the equalize mode the contacts operate to signal the exhaust fan to start.

Temperature Compensation

The temperature compensation circuit is used to automatically adjust the charger’s output voltage up or down based on the temperature read by the temperature probe. The standard probe is internally mounted inside the charger near the bottom of the enclosure near the air intake. This location means the charger and batteries need to be next to each other so the probe senses the same ambient air temperature. External remote temperature probes are also available for those installations where the battery and charger are not next to each other. The remote probe is attached to the battery terminal and connected to the charger via terminal strip. Note: Only one temperature probe option can be used at a time.

High Interrupting AC and DC Breakers

In situations where the available short-circuit current is higher than the breaker's interrupting capacity rating, there may be a failure of the breaker to safely interrupt a fault. This is a major concern in utility transmission and distribution along with oil exploration (offshore oil platforms). In these applications the battery charger specification may require high amperage interrupting capacity rated breakers. An alternative method is to use a fuse in series with a breaker to comply with the high interrupting fault requirements. The drawback to this design is that customers will need a spare fuse on hand to avoid substantial downtime. These breaker ratings are typically expressed in KAIC (Kilo-Amps Interrupting Capacity). One thing to note here is that many times there is a feeder breaker at the distribution source to the chargers that should already be rated for the higher KAIC and is already protecting the charger.
