| EVBonesBMS | Very simple small battery management system (BMS) for Lithium batteries with these characteristics:-
- Very simple analogue circuit
- Under and over voltage alert
- Limited balancing ability, would be improved with a heatsink
- No self diagnosis -- you can't tell if any single module is communicating with the charger or not
- Optoisolated bus

| EV Power Australia Thundersky Battery Balancing System | SIMPLE EFFECTIVE BATTERY MANAGEMENT Lithium Ion batteries require cell balancing during charging and protection from over-charge and over-discharge. The TS-90 Battery Balancing System has been developed specifically for large format Lithium Iron Phosphate batteries such as Thunder Sky LFP series. It can also work with other battery chemistries with minimal modification. The TS90 system consists of Cell Modules, one for each cell, and a master control unit. The cell modules perform the balancing function and also monitor the voltage of each cell in the battery.

| Metric Mind SmoothTalk TM EV Battery Management System | Several versions of the SmoothTalk [TM] battery management system (BMS) are in development to address the need for taking care of individual Lithium based cells used in a traction pack of an electric vehicle. Systems vary in complexity and functionality. There are two main types of the BMS - pure hardware based and regular, controller-driven types.
The hardware based system uses modular charging approach - each cell in a traction pack is charged individually with own isolated 20W charger allowing the cell to take what it needs regardless of other cells in the pack. There are common alarm and end of charge circuits as well as supervisors allowing to make sure there are no failed chargers in the chain. This system will work with or without optional external "bulk" charger. In case it is used, charging time will be reduced, however this option is only allowed for 240VAC mains input since modular chargers utilize full 120VAC supply capacity (which should not exceed 2.4kW). The system will take care of proper charging and - by definition - balancing, but will not prevent overdischarge, limit battery current or collect any battery related parameters. Most if this functionality is included in traction controller or inverter.

| Reap Systems Li-Ion Battery Management System (BMS) | Li-Ion cells have many advantages compared with other battery technologies: they are lighter, more durable, can be stored in any state of charge, and they are environmentally benign. However, they require single cell monitor/control in order to ensure safety and longevity.
Our battery management system (BMS) continuously monitors the status of each battery cell and helps keep all the relevant battery parameters, such as temperature, cell voltage and battery current, within their safe limits.
Designed to perform this essential protection and optimise each cell life, our BMS also maximizes the whole battery pack's performance and ensures safety in use. Compatible with most of the commercially available components for electric systems, and designed for maximum flexibility, Li-Ion BMS 14 is the ideal choice for a vast range of applications.
