Where is the intelligent battery intelligent?

　　The reason why smart batteries are smart because the smart battery has BMS, which is the battery management system. Our company can customize 1 ~ 16 string, and the discharge current can reach a maximum of 200A non -intelligent protective board (BMS) or intelligent protective board (BMS) with power meters and communication functions. The battery management system is a system that can manage multiple batteries (lithium iron phosphate batteries, nickel -metal hydride batteries, polymer batteries, etc.) to form a system of a battery pack. The intelligence of smart batteries is mainly reflected in the function of the battery management system.

　　Generally, the BMS management system has the following functions, and the parameters and functions of different projects are flexibly adjusted according to the situation;

　　1) Heat management (high and low temperature detection and protection): Generally does not involve low -temperature charging projects, try to avoid heating management; overall heat dissipation should be used as much as possible in physical measures of air -cooled or water -cooled cooling;

　　2) Balanced management: It is divided into two types: active equilibrium and passive equilibrium. The large capacity products should be preferred to choose active equilibrium.

　　3) Calculation SOC: Combined with the battery discharge curve, load voltage and current, dynamically estimate the SOC through the current points; the power battery should be controlled within 10%; the energy storage battery should be controlled within 5%error;

　　4) Alarm reminder: Display the various information (voltage, current, temperature, SOC, charging state, charging failure, etc.) of the battery pack, which can be transmitted to the upper machine through communication; The device issues alarm prompt to the user, and the specific faulty type is displayed on the display at the same time; it can also be adjusted according to the customer's requirements and the actual situation of the project.

　　5) Power detection: Generally, the operation of the working conditions must be uploaded to the upper machine for analysis.

　　6) Voltage detection: By amplifying the voltage of the series, the real -time detection of each single voltage is achieved, the voltage detection range is 0 ~ 5V, and the detection accuracy: ± 5mv.

　　7) SOC & SOH status detection: According to the various performance indicators detected, the health status of the battery can be analyzed.

　　8) Display system: Can display voltage, current, temperature, SOC, charging status, charging failure, etc.

　　9) Communication function: Design communication types and functions according to customer requirements: RS485, RS232, UART, I2C and Can.

　　10) Power leakage detection;

　　11) The best charging current control;

　　12) System self -test;
