for sort of nannying all the cells inside their modules and making sure when they discharge and recharge they're balancing properly so each cell behaves itself because if you get a rogue cell especially with lithium ion and the power that this car was putting out you could have yourself a few issues so what you never wanted to do is to push them outside of their boundary of happiness and that's why the charging and discharging process was had to be monitored closely okay so here's the enfield flux capacitor with its additional battery pack that now lives in the boot i've just rigged up the charger and it's charging and balancing so forget the electrical tape that's just to insulate when i'm touching it you see the flashing lights they are the bms's the battery management systems like the overlord of the system if you like that is a NUMBER_TOKEN cell pack it's like um a quarter of the power of the car again here's the charger now here making this noise it's plugged in in my garage my untidy garage and i've put the uh i've turned the lights off so you can see the the three main battery packs under here balancing with their flashing leds there's NUMBER_TOKEN individual cells in here and there's NUMBER_TOKEN cells in the boot and in total that gives you about NUMBER_TOKEN volts and NUMBER_TOKEN NUMBER_TOKEN amps of current but the the system of the car the sort of brain in the car will only cope with NUMBER_TOKEN NUMBER_TOKEN down it took NUMBER_TOKEN months to source the correct spec of cells that we needed for this car to get the right weight power output of affordability and those cells were cocom cells made in korea and they were what made this slightly complicated is they were military grade and you could only order them if you had a military account which i didn't so a lot of negotiation went on hyperdrive ordered these these cells for me their pouch cells and we needed NUMBER_TOKEN of them in three modules which lived under here normally you'd see those cells in a bell supercobra military helicopter and they apparently ran the starter unit for the um the jet engines but also the gatling miniguns on the side of it so they had to be quite light in order to be in a helicopter but they also had to have massive potency perfect for an electric drag car when they package them into the modules they then put the bms in the top and i'll show you footage of all of that um and then we suddenly had ourselves a NUMBER_TOKEN volt car which was capable of of over NUMBER_TOKEN NUMBER_TOKEN amps of output the NUMBER_TOKEN season was pretty interesting actually because it got off to a positive start we we thought we would take a while to get into the sort of NUMBER_TOKEN NUMBER_TOKEN second quarter mile bracket and actually we managed to achieve that with relative ease uh always with my mate nick farrow at my uh my side who um nick was my crew chief and actually like i did became so invested in the car the amount of time it took to do this i thoroughly underestimated it it dominated my life for for three or four years um and that's time that money can't really buy in many ways but i suppose i had this vision i had the consent from my wife chops to to just go for it i had just enough sponsorship money to kind of make it work and that's what we did so the car yes
