I think this battery exchange system is ingenious because it can be used to operate various types of vehicles and devices in the range of about 5 to 50kW e.g. "real" smart-sized cars for 3 or 4 people and 120km/h, garden tractors, lawn tractors, powered trailers, medium-sized pumps and compressors, golf carts, cargo taxis, hotel vehicles, event power supplies, ... A great system that has a lot of potential in terms of technology, price and growth! - Bravo Silence!
Micro cars would be good in the US for local driving.you can modify the car for camp grounds with better suspension and more aggressive tires to handle mud,gravel,uneven roads and higher clearances..all so good for ( future) older people and use a self driving mode for the blind,and or disabled.
Perhaps no need to bring it up to the apartment, perhaps at the ground floor of the building can be some plugs and use to charge these just by the entrance of the building..
Super Genial. Battery Swapp. For All Vehicles. Solar Power, Swappstations Storage, 3 minute Swapp and Gooooo. Thank you for this Video. Can I subscribe to Silence Company???
You cannot lease the batterys in the UK, Can I buy from spain and export this for the UK and lease the battery also do you offer a car that can be driven in the uk on a CBT Licence?
The price is up for debate. 😆 Just joking, what I mean to say is, if we can get them so popular they make millions of these, the cost per unit can be quite low, who knows €5-7K maybe, without battery, but where you pay €25 per month per battery for standard range with unlimited swapping. Now though it's about €12-13K but they are really just starting! Check back for my 20minute test drive video!
@@charbax Thanks, you're really doing a great job, with these coverages, many technologies you made video about few people knows, like E-Ink …etc. + as Computer Science graduate, I enjoyed your interview with Steve Furber.
Those should be everywhere! In Taiwan they use Gogoro battery swapping scooters everywhere in every supermarket, kiosk all over the place people can swap. But for scooters only.. I think crucially Silence needs to partner with other micro car makers, like Microlino, Smart, Wuling, BYD and others, to make this a licence free industry standard... all the micro cars should use same battery shape/size/weight standards as well as payments, battery bookings/reservation systems, all the battery management software also be open standard.. so battery makers can compete!
I don't know if they can support fast charging also. I hope so! Having basic plug charging from home in 4 hours is nice, but also having faster charging support, when that is available (if you have that at home or on destinations you may find public fast chargers available, including Tesla superchargers), would be very nice to support!
€25/month per battery. You can manage with just one battery, then I guess you have about 75km range, with two batteries for €50/month you have 150km range.. So I guess you can keep just 1 battery most of the time for your usual daily needs, and add the second battery for €1/day just only when you need to go a bit further doing some shopping at the next town or driving around the lake or something.. And I am just guessing here, 3-4 years later, when there's new battery tech available, you could pay €50/month for 2 newer batteries with 200km range, or pay just €10/month or €15/month for an older or a new cheaper battery tech with just 50km range. Flexibility!
7:40 high speed charging hasn't been defined clearly here, i think the silence rep is just saying it's high speed charging because you can swap in 30sec I have a silence S01 with the same battery and it has a 0.6kW charger and 5.6kWh total capacity but 4.8kWh from 100% to 0% so 4.8/0.6=8 hours to get from 0% to 100% and more frequently you will do from 30% to 100% in 5h30 so at best you can recharge twice in a day, for long trips it isn't fast enough the battery should be able to handle 2.4kW (so the maximum a schuko house wall connector can do) but the charger would need to be 4x bigger than the one in the battery and probably won't be fanless anymore, but it could be usefull for longer trips as you would get about 50km/h of recharge, so similar to the slowest public car chargers at 7kW to get faster charging, the battery would need to be thermally controlled, so heated when it's under 30°C and cooled when above 50°C which could be done with a charging station that press on the metal body of the battery to transfer heat but even there, as it would be heated/cooled from the outside, you couldn't go much under 1h recharge i think (so about 5kW charging) Tesla and other cars with charging under 30mins can do it because there is coolant going THROUGH the battery
Thank you for all this info, so how can Silence make the S04 that can use Tesla Superchargers and any other Fast charging systems that are being deployed globally? Also, any chance the battery swap stations can more quickly recharge all these batteries, because when this system becomes popular I guess it's better to make sure the batteries are quickly charged back up so the next user can swap to a full battery, especially when there are going to be a lot of users on the network and maybe a limite space to setup these battery swap stations on the side of some gas stations or kiosks or other places those could be at, and better I think that battery swap stations are cheap and quick to build and deploy fully weather proof without needing to be indoors necessarily.. I just wonder if when you plug these in something like a Tesla supercharger if you could go from 20% to 90% in like 5 minutes, not even needing to pay that much for it since it wouldn't be using that much electricity, that would be awesome..
@@charbax Silence batterie will never be able to use a tesla supercharger or other DC fast charging for 2 reasons : -1 It is Direct Current charging, the rectifier (component that convert AC to DC) is in the station and the rectifier in the vehicle is not used. But for that to work, the voltage of the station need to match the voltage of the vehicle battery. The standards for cars are 400V and 800V (and because there is a factor 2 between the standards it is fairly simple to make them compatible). The voltage of the silence battery is 51V so way different. And if they wanted to make their battery 400V, they wouldn't be compatible with their actual vehicles, and the power supply component would be a lot more expensive to handle the higher voltage. I wished they choosed at least 70~90V like other 125cc electric moped, but they went with 51V which is closer to what e-bicyles use (24 to 48V)... That would have needed a bit more expensive component, but would have helped reaching higher top speed than 85km/h more easily and with less heat loss (S01 Peak power is 9kW and at 51V that's 180 amps, so very high current needing very thick wires similar to electric cars at 400V but 75kW or about 90hp, which is why they made the wire run from battery to wheel-motor the shortest possible, to have less 1cm thick copper ^^) -2 it wouldn't charge under 5min at a Tesla charger, as I said in the last comment, under 2h charging need some sort of temperature management. That is what is called the "C" number, if a battery can be charged or discharged in 1h that means it can handle 1C, if it's 30min that's 2C. And since the silence battery is a solid cube (not much surface area compared to volume) and only has an aluminum body as heatsink, I don't think more than 0.5C or 2h charging is safe for it's durability. But I don't think that's a problem for battery swapping stations. I think with 2h charging you can expect 1 slot to be enough for about 20 customers (each swapping about every 2 days 2h*20customers=40h
@@charbaxFor me I hope they thought about people that own a battery and could want to charge it faster in these stations. I'm not comfortable with renting stuff that I will use for a long time. If I can afford it, I prefer owning it. I did 2x 230km trip over 2 days with a passenger and 3 storage cases (right at the weight limit) and reserved in advance a camp site with accès to electricity and restaurants that accepted that we recharge while eating. It was feasible, but not something we would do more than once a year as you can only take 2h max to eat, and that only recharge 25% or 25km, and the trip cost us more than by car since we paid for 2 camp night and 8 meals in restaurants ^^. If we were able to recover 75% or 75km in 1h30 for about 3€ (charge at home is about 1€ for 100km, if 4x faster charge is 4x more expensive I think that's generous to silence) we could do the 230km trip in 1 day Travel 75km in 1h30 Recharge 75km in 1h30 Travel 75 Recharge 75 Travel 80km That would take 7h30 total, from 9am to 4:30pm to avoid rush hours where riding along at 50km/h to watch the landscape and listen for birds is more feasible ^^ The total 2x230km would cost 4x3+2x1= 14€ instead of 50€ by car and about 1kg of CO2 instead of 100kg with a petrol car or 5kg with an electric car
