MSD (Manual Service Disconnect) for Electric Vehicles
Renhotec, a leading expert in electric vehicle safety design, offers top-quality Manual Service Disconnects (MSDs) designed to enhance the safety and reliability of high-voltage connections in electric vehicles.
What is MSD (Manual Service Disconnect)?
MSD is a crucial safety component installed within the battery pack of electric vehicles. It allows for the disconnection of the high-voltage circuit, enabling safer maintenance and minimizing potential safety risks in case of a sudden short circuit.
Why Choose Renhotec's MSD?
Our MSDs are strategically designed in the middle position of the battery pack, reducing the overall voltage into several lower voltage sections. This placement allows passengers to quickly locate and disconnect the MSD if necessary, enhancing the vehicle's safety.

How to Choose an MSD?
MSD should be designed in the middle position of the battery pack. For instance, in a 100-string battery pack, the MSD should be placed in the middle position of the 50-string battery. This design helps to reduce the overall voltage into several lower voltage sections, thereby minimi zing potential safety risks.
When selecting an MSD, several factors need to be considered:
- Rated voltage: If the maximum voltage of the pack is about 400V, an MSD with a rated voltage of no less than DC 450V should be selected.
- Fuse-rated current: The rated current of the MSD fuse should be more than twice that of the load-rated current.
- Load peak current: The fuse current of the MSD should be greater than the load peak current.
- Reaction time: The fuse reaction time of the MSD should be less than the adhesion time of the relay.
Choosing an appropriate MSD is critical to ensuring the safety of both technicians and vehicle owners. Renhotec, a leading expert in this field, guarantees that their MSDs meet the highest standards and offer maximum security. For those looking to enhance the safety and reliability of high-voltage connections in electric vehicles, Renhotec's MSDs are the ideal choice.
