They also have the lowest cost of energy storage due to their deep discharge capability and high cycle rate. As well as, batteries have a high energy density, are safe and easy to manufacture, making them inexpensive and affordable.

Graphene supercapacitor batteries offer the following key benefits

no memory effect after numerous charge and discharge cycles;

the possibility of charging OF Graphene supercapacitor battery with high currents in 20 minutes up to 80% of the capacity;

reliability and safety, confirmed by international certificates;

more than 6 years of successful use in electric transport in China, Europe, and the USA;

Wide operating temperature range from -30°C to +65°C.

Power Graphene supercapacitor battery has many advantages

Power Graphene supercapacitor batteries have many advantages over lead-acid batteries. They are lighter, more efficient, charge faster, and have a longer lifespan. However, they are very sensitive to operating conditions and can cause damage to the entire battery pack. To exploit its full potential, Graphene supercapacitor batteries require complex components to help avoid the risk of battery damage. In fact, this is the main use of a Battery Management System (BMS).

BMS is considered the brain of Graphene supercapacitor battery

A BMS consists of many electronic devices integrated on a single circuit board that monitors and manages all battery activities. Most importantly, it keeps the battery operating within the safe zone in which it is established.

In addition, the BMS is an essential part of safe operation, total performance, and Graphene supercapacitor battery life. Moreover, it also protects battery-powered equipment such as electric vehicles, boats, storage inverters, etc., and to the user.

What is the function of BMS?

Moreover, the main function of the BMS is to protect the battery cells inside the battery pack from damage caused by overcharging or discharging. In addition, the BMS can calculate remaining capacity, monitor battery health and temperature, and ensure safety by checking connections for leaks or short circuits. The BMS also helps balance the voltage between the Graphene supercapacitor battery cells so that the battery pack can use its maximum capacity. If it detects any unsafe phenomenon, the BMS will immediately cut off the current to separate the battery from the system to ensure the Graphene supercapacitor battery cells and users are safe.

 How does BMS work?

The BMS monitors each individual battery cell in the battery pack. Then calculate the safe current capacity that can enter (charge) and go out (discharge) without causing any damage to the battery. Current limiting prevents the input power source (Charger) and output load (DC/AC Inverter) from overloading the Graphene supercapacitor battery pack. This ensures that the battery cell's voltage does not increase or decrease excessively – helping to prolong the life of the battery. The BMS knows when the Graphene supercapacitor battery is fully charged or discharged to limit capacity or control the battery to stop discharging. This is why Lithium-ion batteries don't show signs of dying like lead-acid batteries, but just turn off.

Why is BMS important?

The BMS is an essential component to preserving the health and longevity of your battery, but most importantly, it's about safety. Furthermore, the electrolyte solution inside a Lithium-ion battery is highly flammable. Therefore, these Graphene supercapacitor batteries need to be operated optimally and within safe limits at all times to prevent fire and explosion. BMS battery management system

 The main protection functions of a BMS:

Overvoltage and under-voltage

Damage can occur if the Graphene supercapacitor battery cell overcharges (cell voltage is too high) or over-discharges (cell voltage is too low). BMS helps protect battery cells from overvoltage and under-voltage situations that can shorten battery life or die.

Too hot: Safety and stability of the  Graphene supercapacitor battery

The safety and stability of the Graphene supercapacitor battery cell depend on the operating temperature being within the threshold. If the temperature exceeds the alarm level even without operation, the battery cell rupture may occur. It causes the electrolyte solution to leak. The BMS monitors the temperature to keep the battery within acceptable operating conditions. And will deactivate the battery if necessary.

Short circuit protection

Short circuit inside the cell or outside the device can lead to damage to the battery cell. For this reason, short circuit protection is an essential function of a battery management system.

The BMS is an essential component of a Graphene supercapacitor battery pack to monitor the above. Above all, it keeps the battery running safely and optimally so you can go out without having to constantly keep an eye on it.
