The DC power supply systems of telecom applications for broadband and Internet access have increasing energy demands. However, in many cases the available space for the installation is already used to its maximum. A lithium ion battery can be the solution because of the higher energy density of about 150 Wh/kg and 380 Wh/l, good discharging performance and an operating range from -30degC to 60degC...
In spite of a number of new, alternative power supply back up technologies, batteries are here to stay. Continuous monitoring of back up systems on the battery level becomes a vital factor of many mission-critical installations. In this paper, the authors explore the possibilities of implementation of new generation, state of the art battery monitoring systems based on wireless technology. This technology...
The battery is a vital component in powering wireless networks, and for efficient and safe operation lead-acid batteries are typically kept at controlled operating temperatures (20degC to 25degC). This is a major requirement for base transceiver station (BTS) air conditioners. However, recent developments in electronics allow all active equipment in the BTS to operate reliably at much higher temperatures...
A new sensor will be presented, detecting concentration and temperature inside of lead acid batteries. Inserted into battery-management-systems like for example badicheq, the unit is able to indicate the state of charge under almost any circumstances. It is important to know the state of charge of a lead acid battery and it is easy to detect by measuring the acid level and the acid density. While...
