1. Energy storage subsystem: 2 sets of 6V/200Ah lead-carbon batteries are
used to ensure the needs of continuous long-term working scenarios, while also
considering the application needs of energy recovery;
2. BMS (Battery Management System) : In the current BMS system, there are
two modes:
A. Single collection system - collect the voltage, temperature and other
parameters of each single battery, BMS system does not have A single balancing
function, this kind of system is relatively simple, customers can see the
voltage and temperature of each battery through the background monitoring
system, but the SOC, SOH, internal resistance and other parameters of the
battery (single or group) are not, in terms of high voltage group system, That's
a big miss;
B. Cluster collection system - a collection unit is responsible for the
data collection of up to 27 individual batteries, the data is also voltage and
temperature, the system has the calculation function of SOC, SOH, internal
resistance of single and group, the collection unit can also add a balancing
unit to ensure the consistency of each single battery in a collection unit, but,
The imbalance between the units still exists, and there is also a big hidden
danger: after the equilibrium unit is opened, the system is matched
The interference of the system is great
