Ola 4680 battery Specification in Detail
Ola Electric has unveiled its indigenous made 4680 battery cell, named the “Bharat” cell, marking a significant leap in India’s electric vehicle (EV) technology. Developed entirely in-house, the Bharat cell boasts cutting-edge advancements in battery technology and aligns with India’s push for self-reliance in the EV sector.
Ola’s new cells are bigger, provide about five times as much energy, and have faster charging times compared to the previous 2170 cells used in Ola’s electric scooters. The Bharat 4680 is developed as a new cell with a much bigger form factor and proprietary technology.
What is the Bharat 4680 battery by Ola?
The Bharat 4680 battery is a Li-ion battery, named after its 46mm × 80mm cylindrical size (diameter × height). When compared to 2170 size cells, the height and diameter both are larger. It would replace the 2170 battery, which is currently being used in Ola’s electric vehicles.
The Bharat 4680 battery type would be popular in rechargeable and high-current draining devices considering its higher degree of capabilities like charge cycle and higher energy density.
Ola’s Bharat 4680 battery specification:
| Properties | Specifications | Remark |
|---|---|---|
| Component type | Battery/ Cell | Power supply |
| Battery type | Li-ion | Technology |
| Model No | 4680 | Bharat 4680 battery |
| Size/ dimension | 46 ✖ 80 mm | Standard (dd ✖ hh) |
| Voltage | 3.7 volt | Nominal (std). |
| Capacity | 25- 26Ah | Per cell (estimated max) |
| Operating voltage | 2.5- 4.2 volt | Range (std.) |
| Weight | ~355 gms | (estimated) |
| Charge density (Energy per cell) | 96-99 Wh | Energy (at 3.7V estimated) |
| Charge discharge cycle | ~1500 | (1000 to 2000) in number (depends on nature of charging) |
| Charging voltage | 4.2v- 5v | 5 volt max per cell |
The Bharat 4680 cell, named after its 46mm × 80mm cylindrical size (diameter × height), represents a substantial improvement over the existing 2170 cells currently used in Ola’s electric scooters. Key features include:
- Energy Density: The Bharat cell offers five times more energy density than the 2170 cells, leading to significantly improved performance and range for electric vehicles.
- Charging Efficiency: Enhanced charging capabilities ensure faster charging times up to 1.5X, adding to a better user experience, as the current battery needs to be charged for about 7-8 Hrs to get it 100%.
- Patent Portfolio: According to sources, Ola Electric has secured over 70+ patents related to this upcoming Bharat cell, which indicates the innovative and proprietary nature of this technology.
With the confirmation of the new cell being 4680, the name of this new cell is given: the Bharat 4680 battery cell. This post covered all known and possible Bharat 4680 battery specifications.
Ola 4680 battery size / dimension:
The 4680 battery length is 80mm.
The diameter of the 4680 battery is 46mm.
To be more precise, it has an approximate length of 80mm and an approximate diameter is 46mm.
Thus, you could find specifications written as (say) 46 ± 0.41mm ✖ 80 ± 0.25mm on the datasheet and features of the li-ion cell.
Advantage of 4680 over previous 21700 batteries:
Due to the increase in length and diameter, the overall volume of the cell has increased, thus, with this development, it is claimed that there will be a 5x increase in capacity and a 6x increase in power. Supports one and a half times faster charging rate as compared to the previous 18650 battery.
