What Kind Of Battery For Sweeping Robot And What Is The Right Capacity?

1) What kind of battery is used in the sweeping robot?

The battery is a core part of the sweeping robot, and when the power is insufficient, the sweeper can not work. Especially large families, if the sweeper cleaning to half of the power is insufficient need to charge before continuing to work, although it can be intelligent back to charge, but charging after all, it takes a period of time, it will bring a certain impact on the use. What exactly are the tips for choosing a sweeper robot battery?

 

Here is a brief explanation:

The size of the battery capacity is of course the first point of concern, because it has a direct relationship with the working time of the sweeping robot, the capacity of course to choose a large one. However, it is not the larger the capacity the better, because in order to increase the battery capacity, the size of the battery will be correspondingly large, aggravating the thickness and weight of the sweeper, taking into account the range and the overall performance of the machine, most of the battery capacity of the sweeper is between 2000~3500mAh.

 

 

In addition to focusing on the battery capacity but also to choose the type of battery, different types of battery charge and discharge times, stability, life, safety are different. And most of the sweeper is in the charging state when it is not working, the safety and stability of the battery is a must consider, if the phenomenon of overcharging occurs, it is likely that it will lead to fire and other accidents.

 

At present, several types of batteries commonly used in floor sweeping robots are:

Lithium Polymer Battery

Advantages: small size, lighter, no memory effect, charge as you go, low self-discharge rate.

Disadvantages: safety and stability is not as good as nickel-metal hydride batteries, expensive.

 

Nickel-metal hydride battery

Advantages: high security, good stability, cheap.

Disadvantages: large size, heavy, memory effect, can not be quickly charged, high self-discharge rate.

 

Lithium Iron Phosphate Power Battery

Advantages: light weight, no memory effect, charge as you go, low self-discharge rate, large capacity, high humidity resistance, high-current rapid discharge, long life and environmental protection.

 

Disadvantages: lithium iron phosphate cathode material vibration density is small, the volume of lithium iron phosphate battery of equal capacity is larger than other lithium-ion batteries, so it does not have the advantage of miniature batteries.

 

2) What is the right battery capacity for the sweeper?

Battery type: lithium battery

Battery Capacity: 5200mAh

Duration: 3 hours

Charging Mode: Auto Recharge

Applicable area: 0-300㎡ square meters

 

In principle, the range is generally proportional to the battery capacity and inversely proportional to the rated power, and the higher the rated power can provide the motor with more powerful suction to enhance the cleaning ability.

 

In fact, the endurance is how long the sweeping robot can keep working at a time. The larger the battery capacity, the longer the battery life. Range parameters, although the longer the better, but the sweeper daily sweeping can be completed in about 0.5-1 hour, so the battery capacity is only a plus, not a necessary item.

 

If the sweeper needs to sweep an area of 90-120㎡ square meters, the battery capacity: about 2600mAh is enough; if the area needs to sweep an area of 120-250㎡ square meters, the battery capacity of about 3200mAh is enough; if the area needs to sweep an area of more than 250㎡ square meters, the battery capacity of about 5200mAh is enough.
