Frame-Relay features Frame relay technology has the following characteristics: To increase battery voltage and capacity of a power system, cells have to be connected in series or in parallels. Due to unequal self-discharge and physical variations of the cells as different as it was made in factory, the State-Of-Charge(SOC) of the cells will differ sooner or later in the following no matter whether it been used or not. Therefore, the discharge process has to be stopped when one cell has reached its minimum voltage and the energy in the other cells is waste. The utilizable energy of a series circuit is limited by the weakest cell in the pack. To completely discharge all cells, weaker cells must be recharged. This process is called cell balancing or cell equalizing, which is much more energy-efficient than any other methods. And it is very important for prolonging battery lifespan due to reducing internal resistance and slowly sulfided.

Statistical multiplexing, frame transparent transmission, and error detection are completed at the link layer, but retransmission operations after errors are not provided. The frame number, flow control, response and monitoring mechanisms are eliminated, which greatly saves the overhead of the switch, improves the network throughput, and reduces the communication delay. The access rate of general frame relay users is between 64Kbps-2Mbps, with scalable speed.
Frame relay is an international standard, and is increasingly widely used.
Switching unit-The information length of the frame is longer than the packet length, and the maximum reserved frame length must be at least 1600 bytes / frame, which is suitable for encapsulating the data unit of the local area network. Users can effectively use the reserved bandwidth, that is, the committed information rate (CIR), and also allow users' burst data to occupy unscheduled bandwidth to improve the utilization of network resources.
The Frame Relay protocol simplifies the third layer function of X.25, greatly simplifies the processing of network nodes, and improves the efficiency of network processing of information. The transmission link used by Frame Relay to transmit data is a logical connection rather than a physical connection. Multiple logical connections can be multiplexed on one physical connection, which can realize bandwidth multiplexing and dynamic allocation, reducing the cost of network connection.
Due to the non-broadcast nature of the Frame Relay protocol, the transmission of broadcast packets must rely on the replication of the router, which will reduce the effective bandwidth utilization and reduce the performance of the network equipment.
Provide a set of bandwidth management and congestion prevention mechanisms, but this mechanism requires the cooperation of end device protocols, including routers, WAN switches, etc., otherwise there is no good congestion management.
The interoperability of equipment from different manufacturers may cause a large delay in the frame relay network.
Our Battery Equalizer is designed specially for Electric Vehicle Power, which it packed in series by 12V cells. The equalizer with smaller smart pulse is installed onto battery bank in everyday's driving. Keeping all the batteries in your electric vehicles equalized allows them to be completely charged and to give off a completely discharged. And make to give you a longer travelling distance and better experience. By adding our smart pulse equalizer to your vehicle power battery bank, the cell batteries are desulfated and equalized on a consistent basis so they will always be in as new ones. When there is no internal resistance in the cell batteries, there is less wear and tear when vehicles starting and being speed up. The total electrical power system benefits as the batteries are equal as in like new conditions.
Smart pulse Equalizing system for 48, 60, 72-Volt battery banks, patented pulse technology reduces and prevents sulfation buildup. Maximizes the performance of all lead-acid battery including VRLA, AGM, GEL and Flooded cell batteries.
