Intended for three-wheeled vehicles and electric motorcyclists that run under different load scenarios. It facilitates the frequent braking, accelerating, and stop-and-go usage patterns typical of urban transit.
It is appropriate for medium-to high-voltage systems used in both automobiles and energy storage solutions since it supports 18S–20S battery combinations. This makes it possible to use the same platform for several different product lines.
Continually monitors temperature, voltage, current, and charge level. This allows users to monitor battery performance while in use and modify maintenance or usage plans.
Energy storage systems, monitoring platforms, and car controllers can all be integrated using CAN, UART, and RS485 options. This facilitates system coordination and data interchange between many applications.
Keeps each cell’s voltage constant throughout cycles of charging and discharging, assisting in the battery pack’s balanced energy distribution.
Enables the setting of communication protocols, voltage thresholds, and current restrictions according to the needs of particular applications.
Includes temperature conditions, short circuit, overcharge, overdischarge, and overcurrent controls to regulate battery performance.
Intended for installation in battery packs used in storage systems and automobiles where space efficiency is crucial.
Keeps track of battery consumption information, such as voltage history and charge cycles, for system assessment and maintenance scheduling.
The 18S–20S 110A Smart BMS is appropriate for a range of energy storage and electric mobility systems that need battery control, communication, and monitoring.
Supports electric motorbike battery systems, including power management and monitoring for daily commuting and urban mobility.
Oversees the battery packs used in cargo and passenger tricycles, managing fluctuating loads and frequent stop-start operations in urban settings.
Supports stationary battery systems for small-scale energy storage, solar storage, and backup power.

A: The features of smart active balance BMS: Smart active balance BMS performs better in terms of protection than standard BMS. By automatically adjusting the battery pack’s voltage and current, the smart active balance BMS may provide more accurate protection. Q:Can I run a lithium battery without BMS? A: Any Li-ion battery, LTO, or other chemistry always requires a BMS. Li-ion cells should never be operated unprotected; doing so poses a risk to people and property, and at best to the cells themselves. Q:What does BMS mean on a battery? A: Battery Management System, or BMS, is what a battery is. It is an electronic system that ensures safe and effective functioning by managing, protecting, and keeping an eye on a battery pack. Q:Do I need a BMS with a LiFePO4 battery? A: An important component of your battery system is a BMS. Without it, your LiFePO4 battery—especially LiFePO4 batteries—may sustain irreversible damage and possibly become dangerous. Q:Can you overcharge a lithium battery with a BMS? A: Lithium batteries are shielded from overcharging by the Battery Management System (BMS). An electronic system called a BMS keeps an eye on and controls a number of battery-related functions. Q:Do all lithium batteries have a built-in BMS? A: Certain lithium batteries, such those found in computers and cell phones, could not come with a BMS integrated into the battery pack. To monitor the battery and avoid overcharging or overdischarging, the device itself may incorporate circuitry or a separate BMS module in these situations. |
