Advantages Of 1 kWh Lithium Ion Battery

Grade A Cells

1 kWh lithium battery uses lithium iron phosphate (LiFePO4) technology, providing excellent temperature resistance and can operate in temperatures ranging from -20°C to 55°C. Its stable internal structure, IP67-rated waterproof and corrosion-resistant ABS casing, along with a portable handle, make it suitable for various work environments.

Built In BMS

We use brand new 18650 cylindrical cells, prismatic cells, or pouch cells to ensure cell consistency. In addition to balancing cell uniformity, the BMS monitors the battery’s status. It automatically disconnects the circuit in case of abnormalities and reconnects it once the issue is resolved. Delong rechargeable 1 kWh solar battery is dedicated to providing you with reliable, efficient clean energy.

Long Lifespan

Delong 1 kWh lithium-ion battery has a lifespan of 6,500 cycles, which is 3 to 5 times longer than that of lead-acid batteries, making it an ideal power source for long-term users. The Delong 1 kWh lithium battery maintains a stable voltage without sudden drops. Additionally, it contains no harmful substances, has no restrictions on installation orientation, and requires no maintenance, making it a perfect replacement for lead-acid / GEL / AGM batteries.

Fast Charging

One of the key features of the Delong 1 kWh lithium battery is its strong scalability. It supports increasing voltage and capacity by connecting 2, 3, or 4 packs in series or parallel, making it suitable for higher-power devices or extending the runtime of equipment. Additionally, the 1 kWh lithium battery supports three charging methods, and when paired with the original charger, charging efficiency is further enhanced. With upgraded Bluetooth functionality, you can monitor the battery’s status in real-time right from your phone.

FAQ

kWh is a unit of energy used to measure electricity. A 1 kWh battery refers to a battery that can store 1 kilowatt-hour of energy and provide 1 kW of power over the course of one hour.

The size and weight of a 1 kWh lithium-ion battery can vary depending on its design, application, and manufacturer.

For example, batteries for home energy storage, portable outdoor use, and electric vehicles have significant differences in size and weight due to their different uses.

Delong 1 kWh lithium battery DL-EB112 for electric bicycles has dimensions of 367.490.3127.3 mm, while the 1 kWh 12.8V 75Ah lithium battery DL-LFP-RP1275 has dimensions of 260168211 mm.

Ideally:
A 1 kW charger can fully charge a 1 kWh battery in 1 hour.
A 2 kW charger can fully charge a 1 kWh battery in 30 minutes.

However, in actual applications, the charging time can be affected by the power of the charger, the state of the battery, and the settings of the battery management system.

The price of a 1 kWh li ion battery varies depending on the battery type, manufacturer, purchase quantity, and market demand. For example, the price of the Delong 12.8V 80Ah lithium battery is tiered based on the order quantity.

The nominal voltage of a 18650 battery is 3.7V, and its capacity ranges between 2500mAh and 3500mAh. We know that the voltage and capacity of individual batteries affect the total energy of the battery pack. Specifically:
Total energy (Wh) = Number of batteries x Capacity of each battery (Ah) x Battery voltage (V)

To calculate the number of batteries needed:
Number of batteries = Total energy (Wh) / (Capacity of each battery (Ah) x Battery voltage (V))

For example, if we use 18650 batteries with a capacity of 3500mAh (3.5Ah) and a nominal voltage of 3.7V:
Number of batteries = 1000Wh / (3.5Ah x 3.7V) ≈ 77.2
This means 78 18650 batteries with a capacity of 3500mAh are needed to generate 1 kWh of energy.

In practical applications, the design of the battery pack also needs to consider the BMS, connection method, and other factors. For instance, the Delong model DL-EB006, a 36V 17.5Ah battery for electric bicycles, requires 52 18650 batteries connected in a 10S5P configuration to produce 1 kWh of energy.

The distance that 1 kWh can cover depends on the vehicle’s energy efficiency, which is measured in kilometers per kilowatt-hour (km/kWh). For example:

• Electric cars have an efficiency of about 5 to 8 km/kWh, meaning they can travel approximately 5 to 8 kilometers.

• Electric bicycles have an efficiency of about 20 to 40 km/kWh, allowing them to cover approximately 20 to 40 kilometers.

• Electric scooters have an efficiency of about 10 to 20 km/kWh, so they can travel roughly 10 to 20 kilometers.

However, the actual distance traveled can be affected by factors such as vehicle weight, load, driving habits, terrain, speed, and weather conditions.

For a typical lithium-ion battery, the lithium content is approximately 1% to 3% of the total battery weight. Assuming a 1 kWh lithium-ion battery weighs about 10 kg, the lithium content would be:

10000g x 1% = 100g
or
10000g x 3% = 300g

This means that a 1 kWh lithium-ion battery contains between 100g and 300g of lithium.

In actual applications, the lithium content can vary depending on the chemical composition, design, and manufacturing processes of the lithium-ion battery.

The rate at which 1 kWh of energy is consumed depends on the power of the device (kW).
Time (h) = Energy (kWh) ÷ Power (kW)

For example, with a 2 kW air conditioner:
1 kWh ÷ 2 kW = 0.5 h
A 2 kW air conditioner will use up 1 kWh of energy in 30 minutes.

For a 60-watt light bulb:
1 kWh ÷ 0.06 kW = 16.67 h
A 60-watt light bulb will use up 1 kWh of energy in 16.67 hours.
