How BYD's Blade battery technology slices EV charging times
BYD’s innovative Blade battery gets its name from the long, slim layout of the cells
EV drivetrains and particularly batteries are developing at a remarkable pace compared with the combustion engine.
As a result, range has increased but probably even more marked is the desire to bring charging times in line with ICE refuelling.
BYD recently announced its Super e-Platform along with the latest ‘flash-charge’ version of its lithium-iron-phosphate (LFP) Blade battery, which is promised to get close to ICE refuelling times by recharging in six minutes.
The new platform is claimed to support charging at up to 1000kW, which seems incredible given the typical rapid-charge rate was 50kW just a few years ago.
The name Blade describes the unusual design of the battery, where long, slim cells almost a metre in length make up the pack, rather than modules packed full of smaller pouch, cylindrical or prism cells.
In that sense it’s unusual, but its LFP chemistry isn’t. The advantage of LFP lies in being economical, cobalt- and nickel-free and, above all, safer. LFP battery chemistry is often used in stationary battery systems (including domestic solar systems) and releases heat slowly and doesn’t release oxygen if damaged.
