Today I was dedicating my usual daily WOMBAT (Waste of Money, Brain And Time) into trying to "reverse engingeer" Venture One or construct an all-electric tilting trike using parts available online. While searching I came accros Thunder Sky Energy Group. This company is building large format LiFePo bateries and also some end products - electric scooters and buses. Between their products I found TS-LFP260AHA. This is a large format LiFePo pack with 260Ah capacity at 2,5V - 4,25V (empty - full). Now, take 48 of them and put them into series. You get 53kWh pack that weighs 400kg (800 pounds or 100 pounds less then Roadsters ESS). It's voltage would vary between 120V and 204 V. The pack is rated at 2C constant discharge, meaning this pack is capable of 520A of constant discharge current (for 30 minutes) giving 106kW (full) - 63kW (empty) constant power. But its peak discharge current is rated at 10C giving 530kW (full) down to 312kW (empty) of max power. Smaller 90Ah pack retails for 220 USD at Electric Motorsports so I guess this larger 260Ah pack sells for around 600 USD. This superpack would thus cost around 28k USD. Where are the benefits in comparison to current Tesla's ESS? - lower weight (100 pounds less) for same capacity (53kWH) - lower complexity (no or less cooling required, even less weight?) - much longer lifetime (manufacturer claims 3000 recharge cycles at 80% DOD and even 4000 cycles at 70% DOD) - much higher peak power (from 300kW to 500kW ) Downsides? - somewhat more expensive upfront but it should have 6 times longer lifetime: 100.000 miles for 20k USD (ESS) in comparison to 600.000 miles for 28k USD. If measured in cost per driven mile it becomes 20 cents/mile for ESS and 5 cents/mile for this LiFePo pack. - manufacturer tie-in It is nice to see technology marching on.
