HBLs Nickel Cadmium Pocket Plate Battery designs are based on the superior Pocket Plate technology. The first electrode design for Nickel Cadmium Batteries employed the pocket plate construction which is still considered to be the most reliable design. The fully integrated modern factory, supported by strong process management and quality controls makes HBL one of the best Nickel Cadmium Battery production facilities in the world. In HBL’s Pocket Plate design, the active materials are encapsulated between folded steel strips which are perforated from both sides. This double perforation method increases the effective surface area by 30% and helps in better utilization of the active material thereby making the battery more efficient. The batteries are manufactured in 3 series designated as H, M and L based on their performance capabilities. The H series have thin plates to provide for high discharge currents, the L series have thick plates to provide lower currents for long durations and the M series have an optimized plate thickness which is ideal for medium discharge performance and durations. These Batteries are available as Single cells of 1.2V or in Blocks (individual cells thermally welded and connected either in series or in parallel) of higher voltages (2.4, 3.6V etc) and capacities.

A new reduced maintenance Nickel Cadmium battery developed by HBL for high temperature stationary power backup applications. The major design improvements of this reduced maintenance battery are, 90% capacity is available even at +40° C after constant charge at 1.43 Vcell in 15 hours with a charge current of 0.1 C5 A. Top-up only once during its life time under recommended operating conditions.

Charge input from solar arrays sometimes is insufficient to keep the batteries fully charged. During sun-less days, batteries are discharged but not charged. These conditions result in battery operating in partial state of charge (psoc), cycling and deep-cycling. Also, solar systems are installed in open atmosphere exposing the batteries to extreme temperatures. Other lead acid batteries fail in such conditions due to sulphation, stratification, corrosion and plate shedding. Moreover, remote solar installations make water top-up difficult and costs money. To meet such rigors of usage hbl introduces a maintenance free (no water top-up) tubular gel vrla battery with unbeatable combination of tubular plate and gelled electrolyte, which is a perfect fit for all solar applications.

HBLs Triumph Plus series are advanced valve regulated lead acid maintenance free batteries. Heavy-duty thick plates with unique manufacturing process make these batteries the most suitable for higher cyclic life & efficient performance under Partial State of Charge (PSOC) operating conditions. Also other unique design features improve temperature tolerance hence suitable for higher operating temperature Outdoor site operations. Telecom BTS sites depend heavily on standby power i.e. batteries and DG, due to poor & unreliable grid power. Operating conditions in these areas subject the batteries to deep cycling & partial state of charge operation. The challenge in maintaining site uptime through uninterrupted power is highly dependent on the consistent & reliable performance of the battery. HBL’s Triumph Plus batteries are designed to meet the growing need of reliable power.

Thyristor based battery charger uses Thyristor switching principle for achieving the desired DC output. It basically consists of a transformer, a semi-conductor bridge rectifier, a filter circuit and a control circuit. The AC mains voltage is transformed to a suitable level and fed to the rectifier bridge. After being smoothened by the filter circuit, it rectifies the AC input and feeds controlled DC output to the battery and load. The power output requirement is adjusted by using phase control technique which is provided by the control circuit. The feedback signals from the output to the control circuit are used for maintaining voltage regulation and current limit.

Nickel cadmium Fibre PNE are constructed using Fibre positive and Pasted negative electrodes. The pasted negative electrode are designed with high power density and has less water consumption, thus reduces the periodicity of topping-up the cells with DI water. The sintered micro-porous separators and membrane separators provide insulation between the plates and permits free flow of electrolyte.

Nickel Cadmium Fibre electrode batteries may be seen as 3rd generation (1980’s) technology. Pocket plate is 1st generation (1919's) and Sintered Plate is 2nd generation (1950’s). The Fibre Electrode Technology has been provided by DAUG, Germany (research venture of Mercedes Benz & Volkswagen). The Nickel Fibre matrix used for the fibre plate allows 90% of the electrode volume for holding the active material. The open three dimensional fibre structure also provides good conductivity to ensure excellent electrical performance. Nickel Cadmium Fibre plate technology uses active material free from graphite and iron. Elimination of these elements ensures that the electrolyte does not get carbonated and reduces water consumption. The elastic nature of NCFP electrode enables it to absorb greater shock and vibration stresses. This includes volume changes during charge and discharge cycles, hence the battery can give more number of cycles compared to other battery technologies. The NCFP technology is considerably lighter in weight and hence has high energy density.
