­Solid-State Batteries Coming Closer to Commercialization

Adden Energy will work to scale the battery up to a palm-sized pouch cell, and then upward toward a full-scale vehicle battery in the next three to five years

Solid-state batteries offer all the upsides of the Li-ion batteries that electric vehicles use, but have much fewer downsides. The time it takes them to charge can be measured in minutes, rather than hours, and because they don’t have a liquid electrolyte, they are much safer and far less prone to bursting in

Figure 1: A bidirectional OBC enables new vehicle-to-everything use cases

­Electric vehicle (EV) on-board chargers (OBCs) can take several forms based on power level and functions. Charging powers vary from less than 2 kW in applications such as electric scooters to 22 kW in high-end EVs. Traditionally, charging power is unidirectional, but bi-directional charging is gaining traction. Why bidirectional OBC
