The New 54 kWh LFP Battery Provides the Sion With an Extended Range of up to 305 km and a Maximum Charging Power of up to 75 kW
More Powerful Battery Eliminates Cobalt, Nickel and Manganese
In Surveys Over 90% Of Sion Reservation Holders Voted for a Larger Battery
24th June 2021 – After consultation with its Community, Munich-based mobility provider Sono Motors has opted for a more powerful 54 kWh battery for use in the SEV (Solar Electric Vehicle) Sion. The new battery extends the vehicle’s total range by up to 305 km and its maximum charging power by up to 75 kW. The additional range provided by the Sion’s solar panels remains unchanged at a weekly average of 112 km (245 km per week at peak). The new LFP (lithium iron phosphate) battery is considered to be one of the safest on the market, and also completely dispenses with the use of cobalt, nickel and manganese.
“In our survey, more than 90% of our existing reservation holders voted for a more powerful battery,” said Laurin Hahn, CEO of Sono Motors. “This move is just another example of how Sono Motors is continuing to drive innovation and sustainability, whilst responding to the wishes of our Community throughout the development of the Sion. Boasting greater capacity, greater range, faster charging, enhanced safety features and no cobalt, nickel or manganese usage, this improved battery will strengthen the Sion’s unique market position even further,” Hahn continued.
Key benefits of the enhanced battery include:
- Extended range of up to 305 km (previously 255 km)
- No usage of cobalt, nickel and manganese
- Built with safety in mind and is effectively non-flammable
- New charging rate of up to 75 kW CCS (previously 50 kW)
- Increased life span of up to 3,000 cycles, or up to 900,000 km
Markus Volmer, Chief Technology Officer at Sono Motors said: “The growing EV market is generating enormous demand for longer-lasting, more sustainable batteries. This enhanced battery enables Sion drivers to extend the time between charges, whilst reducing the charging time itself. This effectively optimizes the Sion to deliver easy and affordable sustainable mobility for everyone.”
Climate protection remains paramount throughout production, as it does in every aspect of Sono’s operations. As part of this commitment, the company will therefore offset all unavoidable greenhouse gas emissions generated in production by supporting certified climate protection projects. This includes any potentially incurred through the procurement of the new battery.
In 2017, Sono Motors introduced the public to its innovative and family-friendly solar electric car, the Sion. To date, the company has received more than 13,000 down-payments for the Sion.
