from chemistry to pack
We often see stepped fast charge limits as shown in this BMW iX3 graph. Often the result of a limited test regime applied by the cell supplier (in this case CATL) to establish the maximum charge current for the cell. These limits are them applied by the BMS team and without more data they have … Read more
Different types of chargers by their ratings – Power (kW), Volt (V), Ampere (A), Range based on 7km/kW, Time to charge (For a 60 kW EV), Locations (whether Home, Work, Public) and Region.
When looking at the key parameters in fast charging a battery pack it is worth looking at the complete system. Also, it is good to look from the cell at atomic scale through the thermal system design to the charging algorithms and handshakes [1]. The drive for a 10 min fast charge to reach 80% … Read more
