The rated capacity of a transformer is the maximum continuous output capacity that can be achieved throughout its specified normal service life, such as 30 years. The actual output capacity is the product of the voltage under load (under inductive load, the voltage under load is less than the rated...

All objects in nature, as long as their temperature is above absolute zero, constantly transmit heat to the outside in the form of electromagnetic waves. This way of transmitting energy is called radiation. The energy released by an object through radiation is called radiation energy, abbreviated as...

How to use and maintain the Emma 48V lithium-ion battery electric vehicle correctly? With the advancement of lithium battery technology and the reduction of production costs, lithium-ion electric vehicles with lithium batteries as the main power source have also flown into ordinary people's home...

What is the nominal voltage of lithium-ion batteries generally?A fully charged lithium battery may have a voltage of 4.2V or 4.3V; After discharging the lithium battery, it is likely to be 3.0V. The discharge time of lithium-ion batteries is parabolic, with rapid changes from 4.3V to 3.7V and from 3...

Is it okay to not use a protective plate for lithium batteries? The protective board is designed to protect the battery from overcharging, over discharging, short circuits, and other issues. Since the protective board is so important for battery safety protection, why do some people think that lithi...

1. Dongguan Juda Electronics Co., LtdDongguan Juda Electronics Co., Ltd. was established in 2002 and has been focusing on customized lithium batteries for 19 years.

1. Durability: Lead acid batteries generally have a deep charge and discharge time of no more than 300 times, have memory, and a lifespan of about two years. Moreover, lead-acid batteries contain liquid. After a period of consumption, if the battery is found to be hot or the charging time becomes sh...

Most electric vehicles are lead-acid batteries, and due to the deeper and shallower discharge, the number of cycles will significantly increase. Therefore, according to this theory, frequent charging is beneficial for cycle life, but for the chargers currently widely used in the market, due to facto...

In theory, substances that can burn to produce energy can basically be used as fuel for fuel cells; In lengthy experiments and feasibility studies, the following substances are generally considered ideal fuels for fuel cells: hydrogen (H2), methanol (CH3OH), gasoline, and other types of hydrocarbons...

The first charge does not require deliberately discharging the battery before charging. Lead acid batteries have no memory effect, and it is generally recommended to charge the battery pack when the remaining capacity is 30% to 40%.The specific charging time is as follows:When 1100% of the battery i...
