Effect of ambient temperature on battery life

Mar , 01 2023

1）Temperature will affect battery capacity At different temperatures, the viscosity of the sulfuric acid solution in the battery will be inconsistent. For example, when the battery is at a temperature below 0°C, as the temperature decreases, the resistance of the sulfuric acid solution will continue to increase, which will directly increase the weight of the electrode. The effect of polarization, ...

Three-stage charging of lead-acid battery

Apr , 15 2023

1. What is the three-stage charging of lead-acid batteries? The charging method of lead-acid batteries should be divided into three stages, namely: constant current charging - constant voltage charging - trickle charging. Constant current charging stage: charge to 13.4V with 0.2C10 A current. Constant voltage charging stage: 2.4V/cell, charging time 3h, cut-off current 0.02C10A Trickle charge phas...

How UPS and generator can become the complete critical power solutions

Apr , 19 2023

How UPS and generator can become the complete critical power solutions with uninterruptible power and backup power supplies？ A UPS can support its critical load during utility power anomalies and blackouts – but only until its battery autonomy expires. Conversely, an adequately-fuelled generator can support the load indefinitely, but needs time to start up and stabilise. Operators of any data cent...

Household storage market and profit model

Aug , 04 2023

1.1 The general trend of new energy has been set, and the energy storage industry is rising New energy generation is unstable, and the demand for energy storage arises. The power system needs to maintain a dynamic balance, and when the power generation is too high, the electric energy needs to be converted into chemical energy or potential energy and other forms of energy to be stored. In the trad...

The Role of AC Capacitors in High Speed Circuits

Aug , 18 2023

1、Introduction For low-frequency circuits, resistors and capacitors can be analyzed as ideal devices. However, in high-frequency circuits, these two devices will not be "ideal". Today, our main discussion is about the issue of AC capacitors, which are commonly known as AC coupling capacitors. Their main function is to filter out the DC component of the signal, which is symmetrical about the X-axis...
