Preseries ROXEN Batteries Completed
🔋90% Certified – CE & UN38.3 Nearly Complete
Our proprietary ROXEN battery is now over 90% certified, with CE compliance and UN38.3 testing done. EMC testing is the only remaining test. We're on track to meet global safety standards — paving the way for a safe and powerful market launch.
Here are some of the tests completed:
📦 UN 38.3 – Transport Safety Tests (All Li-ion batteries)
– Altitude simulation – Low pressure test
– Thermal test – Temp cycling from hot to cold
– Vibration – Simulated transport vibrations
– Shock – Sudden impact resistance
– External short circuit – Response to short
– Overcharge – Tests battery with excess current
– Forced discharge – Discharge beyond limit
⚡ IEC 62619/62620 –Tests (Industrial Li-ion batteries)
– Capacity test – Measures rated capacity
– Cycle life – Charge/discharge over time
– Energy density – Power-to-weight ratio
– High/low temp performance – Operation in extreme temps
– Storage test – Capacity after long rest
– Internal resistance – Electrical resistance check
– Efficiency – Charge/discharge efficiency
Nail penetration test done at KIWA test house, Germany. The battery test was a success and result graded A on a scale E - A:
"A - No fire external to enclosure or area for fire protection or no battery case rupture"
