Battery backup cover system

Abstract

A battery backup unit (BBU) system and apparatus is provided for securing and communicating with a BBU for use with optical network terminals (ONTs) and/or residential gateways. In various aspects, the BBU system includes a battery enclosure that is configured to eliminate the unintentional reversal of the polarity for a battery enclosed therein. The BBU system also provides an integrated communication circuit for receiving a variety of connectors.

What is claimed is: 
     
         1 . A battery backup system comprising:
 a battery; and   a battery holder comprising:
 a circuit housing holding a circuit board having a plurality of connectors; 
 at least one battery engagement tab; and 
 a battery connection lead, wherein the at least one of the battery engagement tab and the battery connection lead engage the battery in a particular orientation to prevent a polarity reversal of a battery connection. 
   
     
     
         2 . The battery backup system of  claim 1 , wherein the circuit board further comprises at least one of an alarm indicator and a reset switch. 
     
     
         3 . The battery backup system of  claim 1 , wherein the battery is a lithium-ion battery, a LiFePO4 battery or a rechargeable lead acid battery. 
     
     
         4 . The battery backup system of  claim 1 , wherein the battery connection lead is a leaf-type contact prong or a spring-type contact prong. 
     
     
         5 . The battery backup system of  claim 1 , wherein the circuit housing further comprises a housing base mechanically engaged with the circuit board and a removable access cover to provide access to the circuit board. 
     
     
         6 . The battery backup system of  claim 1 , further comprising a thermistor to detect a battery temperature. 
     
     
         7 . The battery backup system of  claim 6 , wherein the thermistor regulates a voltage to charge the battery. 
     
     
         8 . The battery backup system of  claim 1 , wherein the battery is engaged to a solar device. 
     
     
         9 . A battery cover to prevent a polarity reversal of a connected battery, the battery cover comprising:
 a battery engagement tab to engage the battery; and   at least two battery connection leads to permit electrical communication with the battery, wherein the at least two battery connection leads are oriented within the battery cover such that the battery can only be engaged in a particular orientation to prevent the polarity reversal; and   a circuit housing containing a circuit board having a plurality of connectors.   
     
     
         10 . The battery cover of  claim 9 , wherein the plurality of connectors comprise an Ethernet connector or a two-pin receptacle. 
     
     
         11 . The battery cover of  claim 9 , wherein the at least two connectors are a same type of connector. 
     
     
         12 . The battery cover of  claim 9 , wherein at least one of the battery connection leads is a leaf-type contact prong or a spring-type contact prong. 
     
     
         13 . The battery cover of  claim 9 , further comprising a thermistor to detect a battery temperature, wherein the thermistor is mounted on an exterior of the battery backup system and wherein the thermistor regulates a voltage to charge the battery. 
     
     
         14 . The battery cover of  claim 9 , wherein the battery is engaged to a solar device. 
     
     
         15 . A battery backup system comprising:
 a battery; and   a battery enclosure comprising:
 a thermistor to detect a battery temperature; 
 a circuit housing holding a circuit board having a plurality of connectors; 
   at least one battery engagement tab; and   a battery connection lead, wherein at least one of the battery engagement tab and the battery connection lead engage the battery in a particular orientation to prevent a polarity reversal of the battery.   
     
     
         16 . The battery backup system of  claim 15 , further comprising a cable management system to secure at least one of the plurality of connectors. 
     
     
         17 . The battery backup system of  claim 15 , wherein the circuit board includes a two-position screw terminal. 
     
     
         18 . The battery backup system of  claim 17 , wherein the two-position screw terminal retains wires with a positive and negative contact. 
     
     
         19 . The battery backup system of  claim 15 , wherein the battery connection lead is a spring-type contact prong. 
     
     
         20 . The battery backup system of  claim 15 , wherein the battery is engaged to a solar device.
