Did You Know? Switch Mode Rectifiers, Calculating Float Voltage & C-Rates
Switch Mode Rectifiers The most common technology in use today for stationary battery charging is the Switch Mode Rectifier (SMR). They offer a higher efficiency and are smaller and lighter than the legacy Ferro Resonant and Silicone Controlled Rectifier (SCR) types. More importantly, they are easily field-swappable. Did you know that the SMR was first invented 110 years ago and was a ...

Application of genetic algorithm and neural network for sizing of hybrid photovoltaic wind power generation (HPVWPG) systems
In this paper, a methodology for sizing of hybrid photovoltaic-wind power generation (HPVWPG) system is described. The purpose of this methodology is to predict the PV-generator area, the capacity of the battery and the capacity of the wind generator in isolated (remote) areas, where the meteorological data (solar irradiation, air temperature, wind speed, etc) are not always available. For this ...

Mini Flyer Drone Use No Battery
Most mini flyer drones for consumers can fly for 10 minutes to 30 minutes, and to extend the cruising range, equipping the battery with a larger capacity seems the only one way. However, doing so will actually increase the load of the drone, and the effect on extending the flight time is not obvious. In order to solve this problem, a researcher has developed a new type of drone technology that ...

3 Questions About the Battery of Electrical Vehicles
1. Does the power recovery increase the number of battery cycles? The motor that powers new energy vehicles is almost exactly the same as a generator in terms of component structure and line connection. If you change the direction of rotation of the rotor, the motor can be transformed into a generator. In order to reduce energy waste, engineers added a converter to the power system of the new ...

Drone ESC
Choosing a motor/battery/ fpv drone ESC combo is a combination of science, guess-work, and magic! Here is a process to select the "right" motor, ESC and battery. (1) Estimate the AUW ("All-Up-Weight") of the plane; (2) Select a motor and propeller with (a) the proper thrust, and/or (b) the proper power, given the estimated AUW; (3) Determine the battery voltage compatible with the motor; (4) ...

Why Do We Need Battery Monitoring If We Do Discharge Testing?
Introduction This is a question that is often asked, and the answer is relatively simple. A discharge test measures the capacity of the battery and a battery monitoring system is a maintenance tool. Let me explain further. The Importance of Capacity Testing A lead acid battery is a collection of lead-based electrochemical cells, each with a nominal voltage of 2 Volts, assembled in series to ...

What Reduces Battery Life?
Batteries have become the lifeblood of today’s machines, devices, and equipment. Batteries enable us to use them without an electrical connection. But batteries, as we know, have limited capacity. Sooner we’ll have to plug our laptops, our phones, or replace our car batteries. Batteries have a predetermined lifespan as indicated by the manufacturers’ specifications. However, ...

Why do UPS batteries die earlier than expected?
The battery is an essential part of a UPS. The efficiency of a UPS largely depends upon its battery. Regular care and maintenance of batteries keep them in great shape for a longer period. There are numerous factors behind the failure of UPS batteries earlier than anticipated. Excess usage The life expectancy of a battery is quite dependent upon how much it is used. Batteries break quicker when ...

Coulombic Efficiency Demystified
Let’s say you have a 1-liter bottle of water and you pour all of its contents into another empty 1-liter bottle and then back to the original bottle. A few drops of water spill as you do so. The loss is hardly noticeable - the drops may account for only 1% of the total, so you still have 99% of the water that you started with. This example essentially illustrates Coulombic efficiency - the ...

How the thermal runaway test chamber works?
As the valve-regulated battery uses a poor liquid design, the electrolyte poured into the battery is adsorbed on the fiberglass board. When the charging current increases, the gas needs to be released through the safety valve, which causes the battery to lose water and increase the internal resistance. The capacity decay and generate a lot of heat during charging and discharging. If the heat is ...
