Product Details

Introductions

IEC 60364-7-722 requires that Electric Vehicle(EV) Charging Systems and Electric Vehicle Supply Equipment (EVSE) installed in locations accessible to the public be protected against transient overvoltages, surge current and indirect lightning strikes.
Surge protective devices or PCB mounted thermal MOVs (PCB-TMOV) are necessary to be installed in indoor EVSE, outdoor EVSE and On-board chargers which are more susceptible to surge and lightning strikes.
REPSUN provides the perfect solutions of surge protection for EV chargers and EVSE.

Features

The on-board charger(OBC) is a power electronics device built in electric vehicles that converts AC power from external sources, such as residential outlets, to DC power to charge the vehicle power battery pack.
The off-board charger is connected with the AC power grid to convert the AC power into a controllable DC power supply to charge the vehicle power battery pack. It is generally installed in the DC charging station, also known as the DC charger.

Advantages of PCB-TMOV VS. MOV

PCB-TMOV	MOV
Offer greater thermal protection with mechanical disconnector and avoid resulting in overheating and fire	Without mechanical disconnector MOV in PCB may be burned by the fire caused by thermal runaway due to MOV degradation failure or TOV destroy
With failure indication, ageing indication and optional remote alarm contact	Without any alarm function,MOV in the PCB at risk from potential fire hazard;
Module production approach to improve efficiency of PCBA	Conventional production approach
Improve the safety of OBC builtin EV and ensure the service life of EV chargers and EVSE	The cost to repair or replace the damaged charging equipment is higher caused by MOV failure.
