Charging Protocols

Approaches to charging:

• Constant Current – Constant Voltage (CC-CV)
• Constant Power – Constant Voltage (CP-CV)
• Multistage Constant Current – Constant Voltage (MCC-CV)
• Pulse charging
• Boost charging with a CC-CV-CC-CV scheme
• Variable Current Profile (VCP)
• Stepped Constant Current – Constant Voltage (SCC-CV)
• Non-Linear Voltammetry (NLV)

Legislation, Rules and Regulations

• ISO 15118 defines the vehicle-to-charger digital communication protocol that carries out the negotiation these charging algorithms feed into, including plug-and-charge authentication and charging-schedule exchange.
