Hello, how long does it take for an 84V20A battery to be fully charged with an 84V2 1A charger?

Look at the original storage power of the battery, generally speaking, when the power is low, 20ah hours) or more.

Theoretically, it takes 11 to 12 hours to fully charge, and the charging time is very long in the later stages of charging. These two are supporting lithium batteries and chargers, lithium battery chargers belong to constant voltage and constant current charging, 72V belongs to twenty strings of ternary lithium battery packs, charging later (after 80V, at this time the charging capacity has been completed about 90%), the charging voltage is getting closer and closer to the full voltage, the charging current will gradually decrease, the charging time will gradually extend, to the end of the charging period (above 83V), the charging current is reduced to, until the charging voltage reaches 84V, the charging current is reduced to, and the charger jumps to the green light, The charging current is converted to a trickle of tens of mA for balanced charging.

Theoretically 10 hours, in practice, was. It usually takes 12 hours, of course, with the use of the battery, its capacity will slowly decrease, and the charging time will also decrease.

Hello: 1. There is battery chargingTwo types: Constant current charging mode, or constant voltage charging mode.

Constant current chargingWays to do this:

The capacity of the battery is:AmpereahInstead of a! — the batteryFully chargedThe time required is: (20ah =.)hhours

formulafor chemistryConversion efficiencycoefficient, which manifests itself in the form of fever.

The output voltage of the 84V battery charger is 102V, the charging current of the 20Ah battery is An, when the new battery capacity is full of An, the charging time is 8 hours after discharge, the charging current is ampere in the first 7 hours, the charging current gradually decreases in the next hour, and finally to the charging current ampere, and the charger jumps to the green light.

Conversion efficiency at the input of the charger.

Charging process, alternating current.

Power consumption = (102 * Wh = kWh.

Generally, the single-grid voltage of the battery is 2V, and the charging is at the end, a 12V battery is composed of 6 cells, and the charging voltage is composed of 7 fast 12V batteries in series, so the calculation should be. But when you unplug the charger, the low voltage will drop to about 90V after a while, and it is normal to be higher than 84V. But do I feel the need for such a high voltage?

Personally, I think that the voltage of 48V is not low, my car is 48V, and it feels very strong. And such a high voltage is also unsafe, 84V is much higher than the safe voltage of 24V, and people are at risk of electric shock, especially on rainy days and when there is standing water on the road. Don't think that this voltage is still very low, and the electric shock is just a numbness, which can be easily removed, you must know that you are on the highway, and the electric shock can easily cause a secondary accident.

Calculated by 80% conversion efficiency of kWh.

Ideal loss-free state.

Summary. Dear, hello, I'm glad to answer for you, 84V, 12A charger, how much electricity does it take to charge for an hour, help you find the following answer: 84V, 12A charger Its output power is about 12W.

At this time, the charger trickles up for an hour to consume kilowatt-hour power.

84V, 12A charger, how much power does it take to charge in one hour.

Dear, you Gao Qihao, Hengru is happy to answer for you, 84V, 12A charger, how much electricity does it take to charge for an hour, to help you find the following answers: 84V, 12A charger Its output power is about 12W. At this time, the charger trickles up for an hour to consume kilowatt-hour power.

Pro, the calculation is as follows: 1. Calculate DC power: 48V 12A charger is the DC power of its only mountain object.

p=48x12=Calculated AC power: This type of charger generally uses a high-efficiency switching power supply. The conversion efficiency is usually above 93% and is calculated as 93%.

Split jujube AC input power p'=576/。3. Calculate power consumption: power consumption for 1 hour w=.

That is, its power consumption is in degrees.

Summary. Dear, hello is a pleasure to serve you, 84V, 12A charger, charge for one hour with LCOE.

84V, 12A charger, how much power does it take to charge in one hour.

Hello, I am happy to serve you, 84V, 12A charger, charge and carry sleepy for an hour with the degree of argument key to read electricity.

The charging capacity of the electric vehicle battery is generally multiple of the battery discharge capacity, which is calculated according to the charging voltage, and the infiltration amount of the electric vehicle = charging voltage dust ridge * battery rated capacity *. Stupid search.

Charging Notes:1Pay attention to the state of the charging port, before charging the charging port, the charging port must be photographed, and the liquid must be kept dry first, 2Do not charge in extreme environments, 3Try not to wait until the battery runs out before recharging.

Summary. This question is up to me, I'm glad to serve you, I'm sorting out the answer for you, please wait a few minutes.

Hello, I am a co-teacher who asks questions, and I am good at answering questions you want to know, and I am very happy to serve you. Your question has been received, it takes a little time to type, please wait for a while, please don't end the consultation, you can also provide more effective information, so that I can better answer for you.

Dear, the conversation is in the queue for manual answers, and I have seen the questions you have fed back, so I don't need to ask them repeatedly

I will talk about it late with the charge of the battery of 80ah. 72V lithium battery, composed of strings 72V, full voltage capacity battery, with a charging current of 8A 16A, charging time 5 10 hours. The output current of the charger is 10A, which can be used, the charging time of the 80Ah battery is about 8 hours, the charger is full of voltage 84V, and the code is suitable.

Summary. How big can an 84V10A lithium battery charger charge charge 72V200A.

If the nominal specification of the charger is 84V, then it cannot charge the 72V battery pack;

If the no-load output voltage is 84V, it can be used to charge a 72V battery pack;

However, the output voltage is too high, which has a negative effect on battery life.

No. The working voltage of the charger is 12 volts higher than the rated voltage of the tram battery, so that when charging, the charging current is significantly greater than the rated working current of the battery, and it is easy to cause damage to the tram battery due to heating.

Use an 84V dedicated charger. A charger that is too large for a long time will damage the battery.

Electric vehicle battery is the power of electric vehicles, the vast majority of electric vehicles are equipped with lead-acid batteries, lead-acid batteries are low cost and cost-effective. Because this kind of battery can be charged and charged and can be used repeatedly, it is called a lead-acid battery.

In 1860, France's Plantai invented a battery with lead as electrodes, which was the predecessor of the lead-acid battery.

Class. There are four types of power batteries that can be used by electric bicycles, namely valve-regulated lead-acid maintenance-free batteries, colloidal lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries.

Lead-acid batteries are widely used and widely studied by various electric vehicles in various countries because of their cheapness, abundant materials, high specific power, mature technology and manufacturing process, and high resource rate. As a labor-saving, convenient, fast, comfortable, inexpensive, and zero-emission personal means of transportation, electric bicycles have been widely accepted by people, and have been stimulated to the attention of relevant national departments.

The research group of "Research on Development Strategy of Light Electric Vehicle Industry" participated by the Development Research Center, the Ministry of Construction, the Ministry of Science and Technology and other ministries and commissions put forward the report on "Research on Development Strategy of Light Electric Vehicle Industry". The number of electric bicycles in the country has reached more than 30 million. 95% of e-bikes on the spring lead smile use valve-regulated lead-acid batteries.
