USB PD/PPS direct battery charge controller script for the YK-Lab Shizuku USB tester (a.k.a. YK-Lab YK001, AVHzY CT-3, Power-Z KT002, ATORCH UT18).

Single-Cell Li-Ion Battery Charger with Monitoring

Xling, a pocket demon

Reverse engineered circuit board of the HX-2S-JH20 PCB . Aka 2S 10A w/Balance Li-ion BMS Protection Board.

cideMOD solves DFN physicochemical equations by Finite Element methods using FEniCS library. It enables doing physics-based battery simulations with a wide variety of use cases, from different drive cycles to studies of the SEI growth under storage conditions. Thermal and degradation models can be used to obtain more realistic predictions.
