Bounce Infinity, Clean Electric Launches Portable Liquid-cooled Battery Tech

Electric scooter manufacturing startup, Bounce Infinity in partnership with Clean Electric, a battery tech startup, has launched India's first portable liquid-cooled battery technology. Incorporated into the Bounce Infinity E1 model, the innovative battery technology now facilitates a real-world range of around 100 kilometers.

Additionally, the system allows for fast charging—up to 80 per cent in 45-50 minutes—eliminating the concerns of going to specific fixed charging points that support fast charging. Bounce will be the first EV two-wheeler OEM to launch a liquid-cooled portable battery that enables fast charging using a portable charger.

This technological milestone represents a significant leap forward in electric vehicle (EV) performance, promising an extended range, rapid charging capabilities, and an enhanced battery lifespan. The vehicles are available for purchase at an ex-showroom price starting at Rs. 99,210.

The new liquid-cooled battery offers a substantial increase in energy capacity, boasting 2.5 KWh, and delivers a real-world range of 112-120 kilometers on a single charge, increased from the earlier 1.9 kWh offering 85 kilometers range. Despite the advanced technology, the batteries maintain a competitive weight of approximately 14.5 kilograms. 

Unlike air-cooled batteries that rely on ambient air for cooling, liquid-cooled batteries employ a fire-retardant liquid which efficiently absorbs heat from the battery and transfers it to external metal components. Subsequently, these components can rapidly cool down through exposure to ambient air. The efficient heat management system of the liquid-cooled battery significantly reduces the risk of overheating, a common issue in high-performance electric vehicles. This approach not only facilitates fast charging but also significantly enhances safety by preventing the battery from overheating & creating of hot- spot inside the battery.

The Battery Pack is equipped with 5 layers of safety stack, Cell Level Fusing, Pack Level Main Fuse, direct contact active liquid cooling, software safety protections, and master-slave BMS architecture for N+N redundancy. Also, Clean Electric's innovative cooling approach enables 2-3 degree temperature homogeneity across 140 cells present inside the battery pack enabling 30-50 per cent higher life than conventional air-cooled battery, it means that Bounce Scooters will still have an 85-90 km range even after 5 years (85-90 per cent SOH*/ battery health after 5 years).

Both companies are together working on the Long Range e1++ to double the range with a secondary battery under the footboard, also providing compatibility with universal Type 6 Public DC charging standards for Light Electric Vehicle this year.

On the launch, Vivekananda Hallekere, CEO & Co-Founder of Bounce Infinity, said "Our liquid-cooled batteries are portable and can be conveniently charged at any standard 5 amp socket and fast charged at 15 Amp socket found in every household, just like the ones used for appliances such as refrigerators and heaters. This, combined with fast charging, affordability, and sustainability, empowers individuals to embrace EVs and experience the freedom of electric mobility.”

The battery components are also recyclable, aligning with global environmental standards. Despite the advanced technology, the cost of the battery remains affordable, ensuring that the benefits of liquid cooling are accessible to a broad audience.

Adding to this, Akash Gupta, CEO & Co-founder of Clean Electric, said “We are pushing the boundaries of innovation in battery technology to enable long-range, rapid charging EVs with un-matched battery safety to power the EV revolution by developing battery technology ground up specifically designed for the harsh operating conditions in India”
