E-bike Battery Power System 

Battery management system ( BMS), battery cells, charger and housing, are the main component of the e-bike battery system. Each component has its technological features. These individual component has been developed and makes compatible with each other to provide the best product to the customers. This results in the maximum efficiency with perfect riding experience for e-bike user.

Battery Management System (BMS)

E-bike BMS is an electronic regulator that monitors and controls the charging and discharging of rechargeable batteries. It monitors the battery state such as voltages and currents, Protects the battery from being over-charged or over-discharged. Standard BMS are simply designed to work with any e-bikes system. Few E-bike companies are using different communication protocols, such as CANBUS, UART, and SMBUS, to connect the battery with multiple devices. Melasta uses all kind of BMS according to the customer requirement.

Battery Cells

The battery cell is an integral part of the battery pack. Melasta provides a unique experience to the customers that they can modify their batteries according to their requirements, and these batteries will be compatible to the drive systems. It uses different chemistries for different kind of battery packs. Most commonly used chemistries for E-bike battery packs are LiCoO2, LiFePO4, and NMC. Melasta is an authorized dealer of brand cells, such as Panasonic, Samsung, and Sony, and uses Brand cells as well to make the e-bike battery packs.

Charger Design

Compatibility of the charger along with battery pack is very important for the long life and good performance of the battery pack. Melasta has a dedicated Research and Development(R&D) teams that focus on innovation and quality products for our customers. It provides the best quality charger design service for full compatibility and fast charging.

Battery Housing Design

Hosing makes the compatible physical shape of the battery pack with the e-bike drive unit. It is the final shape of the battery pack. Melasta uses the standard housing for replacement batteries and provides the customized as well according to the customer demands. It uses materials according to the international standards for safety and environment protection. It also provides 3D housing design service to check the housing case compatibility with an e-bike.
