Guide Batteries can be optimised to power auxiliary systems such as heating, ventilation and air-conditioning (HVAC), often the second largest consumer of energy onboard a train. The battery can also be used to provide power during train cleaning or for movements within a depot, removing the need to raise the pantograph or start a diesel engine.
Guide Depending on the battery technology, the voltage may gradually slope off over time, or it may only dip a couple of tenths before suddenly giving out all at once. So generally you can tell the difference between a fully charged battery and a nearly dead one by measuring voltage, but it can be difficult to tell with partially discharged batteries.
Guide To fully charge a nickel-cadmium (NiCd) battery, you typically need to apply a constant current or voltage charging method, ensuring that the battery reaches its maximum capacity without overheating. The ideal charging voltage is around 1.4 to 1.5 volts per cell, and it''s important to monitor the battery to prevent overcharging, which can lead to damage. What

Guide "Professional" battery SoC calculation is done by integrating the area under the current-vs-time curve, essentially to count how many coulombs of energy is going into or out of the battery, & comparing that to either (a) the theoretical/designed coulomb capacity of the battery, or (b) keeping track over long periods of time how many coulombs you get out of a ''full
Guide If the vendor is honest, it''s not too difficult to calculate.. The computer has a "39994 mWh" battery, that is, about 40 W-h (i.e., can supply ~40 watts for 1 hour). A full charge would have to provide at least 40 W-h, and a bit more, because charging is not 100% efficient.; The rating of battery packs seems to me a bit deceptive: they often give the capacity in mA-h,

Hitachi Rail's battery-powered tram technology offers the major benefit of requiring no electrified infrastructure. Our trams can operate on sections of routes with no overhead wires, such as historic city centres, like Florence, Italy, and offer range increase of up to 5km.
The new technology is based on an onboard energy storage system (OBESS), with scalable battery capacity. It can be installed directly on the roof of existing trams - saving on costs, and visual impact – all while ensuring better environmental performance for a more sustainable society. In Florence, battery powered trams have been tested since 2021.
It looks to me, that on a quick look, a 128 kWh battery could provide a useful range for one of Stadler's Class 398/399 tram-trains. The distance between these two stations is six chains over a mile, Adding the extra bit to the flourish might make a round trip between Cardiff Queen Street and The Flourish stations perhaps four miles.
Consider a typical urban tramway with stops located 500m apart, a speed of 50km/h (31mph) between stops, and an acceleration rate of 1.3m/s/s. During acceleration, mechanical power input is converted to kinetic energy of around 5MJ. To overcome rolling resistance over the 500m between stops will require 0.51MJ (0.14KWh).
For reliable service, a tram should be built for 30-40 years. Saft sized the batteries to provide a lifetime of at least seven years, matching CAF's maintenance intervals.
