BYD ECB35 forklift BMS battery management system, function and function description

core monitoring function

Real-time acquisition of full-dimensional state

The system can collect the voltage, temperature, charge and discharge current and other core parameters of each cell in the battery pack in real time. The data update frequency is adapted to the high-frequency operation scene of the forklift, which can accurately capture the subtle state changes during the operation of the battery. All collected data will be stored and archived synchronously, which is convenient for subsequent operators to retrospectively check the full cycle operation of the battery and provide a reliable data basis for battery performance evaluation.

Cell dynamic balance control

The system can dynamically adjust the power difference between each cell according to the collected cell status data, reduce the performance deviation between different cells, avoid long-term overcharge and over-discharge of some cells, and delay the performance of the entire group of batteries. Decay speed to ensure that the performance consistency of the entire group of batteries is within a reasonable range.

safety protection function

Multi-level abnormal warning prompt

The system has built-in multi-dimensional abnormality determination logic. When the battery is detected to have abnormal temperature and current beyond the safe range, it will issue a hierarchical warning prompt through the on-board display end point at the first time, reminding the operator to take corresponding measures in time, and investigate potential safety hazards in advance.

Linkage safety control mechanism

When a serious abnormal situation exceeds the warning threshold, the system automatically links the power output unit to limit the charging and discharging power according to the preset safety logic to avoid further expansion of the abnormal situation, ensure the safety of the operation of the operator and the equipment, and reduce the loss of unnecessary equipment failure.

Energy efficiency optimization function

dynamic output strategy adjustment

The system can dynamically adjust the output strategy of the battery according to the power output demand of different operation scenarios of the forklift, reduce the ineffective energy consumption as much as possible under the premise of meeting the operation power supply, improve the operation time under unit power, and indirectly optimize the battery life performance of a single group of batteries. At the same time, it can also reduce the operation and maintenance investment cost of subsequent batteries.
