from chemistry to pack
Swapping battery packs has come and gone, only to return in force with NIO having swapped 20 million packs (up to May 2023). However, how does this compare to fast charging? Battery Swap For this comparison we are using the 100kWh NIO ES6 as the default. Fast Charging For fast charging perhaps the Porsche Taycan … Read more
Current from the Grid (AC) goes through EVSE (Charging Station Either Level 1 or 2) through a connector to the On Board Charger. The Onboard Charger rectifies or converts the current into DC and sends it via the Battery Management System (BMS) to the Battery Pack
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.
This article reviews and looks at designing swappable batteries. When plug-in charging is replaced with swapping, it leads to some non-obvious differences. Through the prism of practical situations, the readers can understand what is important in designing swappable batteries including the development of its concept, choosing the optimal form factor, and working out external parts … Read more
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
