Anyone got any idea what will cover the 196/SL6 when it comes into service? T’s? HA’s? One big hunch for the SL6 could be the SL1 HAs, they do have the livery of the superloop and wouldn't take long to refurbish. 196 could use the ex 405 HTs or HVs That is not possible because the HTs will be in use on Route 405. Depending on what actually happens over the next few months we shall see anything that gets transferred in will probably end up on other routes and HVs with LED blinds end up on the 196. Ts are out of the question because all the routes go into the ULEZ except the 2/N2 so I doubt it. The SL6 will be interesting because it might be possible to park the buses at Brixton Tram Shed and charge them there until the Power is switched on at N. |

I wouldn't be overly surprised if it is the 50's HVs that end up being the buses that are indirectly used on the 196. |

Charge them between peaks at BN(especially since most of the EVs at BN will be out on their associated routes during that time period), with schedules somewhat similar to how the current EHs have a layover at RA between peaks. The vehicles could then be parked up at N overnight. |

Even on central routes with a service speed of 6mph they would only last for one full day plus whatever they dare on day two - I think it's highly unlikely that they would risk two full days out of them. But there are all sorts of inventive schedules around with the weekday runout not finishing until 1100 and night buses running out at 1500 &c. The beauty of EVs is that although you might need a charging spare or two, you need fewer engineering spares. |

It will still be charged each night - I've seen plenty of diesel buses which stay in the garage all day, go to McDonalds in the evening to pick up food for the late shift engineers and then are put on the fuel line and take 3 litres before being washed and put away. That SL6 coming back with 70% charge might need to be subbed for a mechanical bus tomorrow evening and it might end up being out until 0200. If it starts tomorrow with 70% charge then that might not be possible and the question will be why did we lose mileage because we decided not to charge that bus up yesterday. You never know what tomorrow may bring and so it's a belt and braces job. The batteries will be designed to be charged to 100% every night anyway. |

No that's not how it will work with electrics, constantly juicing an electric up to 100% will do nothing but kill a battery at a rapid pace. |

No that's not how it will work with electrics, constantly juicing an electric up to 100% will do nothing but kill a battery at a rapid pace. They are rapid charged at 350kW each night which is also bad for battery life. For this reason they have a much bigger buffer than traction packs for cars. Basically they are designed on the understanding that they are going to be 'abused' and therefore they are sized accordingly. |

That however doesn't mean that a bus will still be topped up every single night, the SL6 buses will be route bound as well. Where did you hear about them having a bugger buffer? A battery is a battery and regardless will behave the same way. |

I remember a couple of them did the route when the 157 and 417 were still at N. |

A battery is a battery and regardless will behave the same way. A private car has a buffer of perhaps 10% - meaning that the usable capacity of the battery is about 90% of the actual size - in this the motorist will not notice any degradation for the first few years of ownership. Someone will be able to give the exact numbers but I recall that the buffer on traction batteries on buses is much larger. You'll recall that CATL's next generation of traction batteries will come with a warranty of 16 years or 900,000 miles, and battery capacity is guaranteed for that period. Such warranties would not be possible were it not fo a generous buffer at both the top and bottom ends of the battery to disguise the inevitable degradation. They are designed to be charged every night because almost every PCV application will require it. There's plenty of operating data out there now as EVs have been around in quantity for almost a decade. Batteries on buses will be 'abused' and are more generously sized to hide the resulting degradation. Unlike cars, traction batteries on buses will spend a much longer period of the day being either charged or discharged - they have a much harder life and that is designed for. |
