Unity Power Factor
Incorporating Efficient Transformer Design that has optimised flux density and a high-density aluminium conductor, Efficient and Powerful Circuit that uses high current density switches with lowest gate charge and a robust Temperature Compensation mechanism that is designed to handle 2.25 times the rated capacity, Unity Power Factor at bulb load is achieved.
360-degree changeover synchronisation
Using the highly accurate Failure Angle Measurement Technology that measures the grid failure point by dividing its waveform into 360 points and stores the data to start the waveform from the very same point to keep the DC component being produced under 5% and Residual Energy Measurement Technique that equates the distribution angle by measuring the residual shift of hysteresis curve as soon as the grid power fails, an almost perfectly synchronized changeover is promised to protect the equipment running on it from the DC component.
Fuzzy logic control-based input power factor correction
Using the Advanced FLC Algorithm Technique that employs software based FLC logic to synchronize the charging pulses in sinusoidal pattern with highest duty at 00angle and lowest duty at 900angle to fetch the maximum power when the waveform is at lower degrees, Measuring the Frequency Shift, Measuring the Shift Error and with the Fastest Pulse Correction (66 microseconds), the technology ensures near to unity power factor while charging with reduced electricity losses. This is a first of its kind PCU in India.
Battery Less/Free Pickup
Inbuilt Deep Discharge Protection that can revive the power backup system event at zero volt. As soon as the grid is connected, a NC switch supplies the power to the power transformer. A DC supply is then generated using an H-Bridge topology and is used to charge the batteries, including those with zero or low voltage.
Crest Factor 3.3:1
A higher crest factor indicates that the system can handle significant short term power spikes effectively. The Continuous Peak Handling Technique ensures that devices within the power circuitry are rated for continuous operation at levels equivalent to their peak handling capabilities, thus facilitating the attainment of a high crest factor. In parallel, the Module-by-Module Loss Reduction approach is employed to achieve the industry's peak crest factor by systematically minimizing losses across all components involved in delivering backup power, spanning from the DC wiring to the switching devices and static transfer devices. This optimization results in the ability to accommodate peak currents reaching 330% of the rated current at the specified voltage levels, achieved by minimizing wire DC resistance (DCR) to its operational limit, as well as reducing switching and conduction losses of the devices to their peak current capacity, and simultaneously mitigating DCR and reactance in static transfer devices to handle peak currents. The combined result is a rapid rate of current change (dI/dt) across the entire product, yielding a remarkable crest factor of 3.3 times, thereby confirming the product's capacity to effectively deliver genuine power.
GPM Technique
The gravity profile management technique serves the purpose of reviving deeply discharged batteries suffering from hard sulfation, preserving the capacity of aging batteries, and ensuring that batteries are charged to their optimal charge acceptance level. This approach employs multiple strategies, including Continuous Monitoring of Battery Voltage for foldback, whereby an internal algorithm stores foldback points to prevent energy losses and overheating, automatically adjusting the gravity profile to sustain the battery. Additionally, it Continuously Measures Charging Current, reducing it to the charge acceptance level when necessary to avoid excessive losses. Furthermore, a Pulse Current Technique is employed to counteract hard sulfation caused by low electrolyte levels, with intermittent current pulses used to revive the battery and mitigate the adverse effects of sulfation. These combined techniques help maintain battery performance across various environmental conditions and battery ages while preserving charge acceptance levels.
Auto Revival from Over Temperature
It restores power promptly once the internal system temperature falls within desired limits, employing a temperature guard algorithm that continuously monitors critical component temperatures; if they exceed specified limits, the system safely shuts down, records conditions, and resumes from the same point upon restoration.
ECAC Technique
Improved THD among its peers even at heavy inductive loads: Error check analogue compare technique is being used to improve the THD (Total Harmonic Distortion) of the output waveform. In this technique, a closed loop feedback algorithm is being used.
Highest MPPT efficiency
Reaching an impressive efficiency of up to 98%, a remarkable 6.6% higher than competitors, is attributed to a two-fold approach. First, a unique technique in the buck converter effectively minimizes power loss related to the DC side input diode. Second, the buck converter is designed to operate at a frequency four times higher than that of competitors, significantly reducing the size of magnetic components, ultimately leading to enhanced system efficiency.

App Monitoring
Our Lithium-Ion batteries are equipped with a monitoring app that provides real-time updates on battery status, such as remaining charge, any active protection mechanisms, as well as the ability to remotely lock and unlock the battery, among other features.
Cell Characterization
Considering different criteria as modeling perspectives (electrical model, electrochemical model, thermal model, mechanical model, or combinations as electro-chemical models), used equipment (Source–load, climatic test chamber, shaker, etc.), levels (material level, cell level, pack level, system level), methods (sequence of pulses, electrochemical impedance spectroscopy), time scale of the models or characterization standards.
Robust Battery Designs
The robust, high-quality structures of our battery packs ensure their resilience even in the harshest road conditions, leading to an extended lifespan. Following exposure to severe custom vibrations, drops, and shocks, our batteries experienced only a 3.5% degradation in actual capacity, whereas competitor batteries exhibited a 6-7% decline.
Battery System Evaluation
Our energy storage research team conducts a series of tests on commercially available batteries, ranging from the cell to pack level. These tests include aging, thermal, abuse, and vibration testing. Additionally, the team routinely disassembles battery packs to identify failure mechanisms that must be addressed in our battery pack designs.

Our engineers are experienced in the test and characterization of battery cells, modules and full battery packs and we are using our experience to develop next generation test strategies. While our primary focus is on vehicle propulsion applications, we are equipped to handle battery testing for other sectors including static power storage, consumer goods and more.
Thermal Characterization
Understanding the thermal behavior of a cell, module, and the complete vehicle battery pack under various operating conditions, including real-world drive cycles, is crucial for the design and development of successful cooling systems. Our capabilities extend from the thermal characterization of a single cell to the evaluation and optimization of different cooling technologies for vehicle packs.
Thermal Cycling
Cycling through two temperature extremes, typically at relatively high rates of change. It is an environmental stress test used in evaluating product reliability as well as in manufacturing to catch early-term, latent defects by inducing failure through thermal fatigue.
