DESCRIPTION

BMS (Battery Management System) is a system to detect the status of Li-ion batteries and control the charge and discharge promptly to keep the operation safe and extend battery life. Without BMS, Li-ion batteries may damage or explode due to improper use.

This product is a MCU adaptor board of HT45F8650 28SSOP. You can use it with development board, ESK-BMS-200, voltage calibration board, and development platform, the BMS Workshop, to complete a BMS management system.

There are four MCU adaptors that can use with ESK-BMS-200:

In the workshop, you can set multiple parameters and then generate program codes and schematics. Codes can be programmed into the MCU adaptor board via e-Link and HOPE3000 for e-Link software. A programmed MCU provides the BMS protection functions.

BMS Workshop includes seven protection functions: charge protection, discharge protection, charger voltage protection, charge current protection, short-circuit protection, and temperature protection.

Programming tool: e-Link and HOPE3000 for e-Link
Development platform: BMS Workshop

Why do I need the Li-ion battery protection functions?

If the Li-ion battery is used improperly, the battery will be damaged, and there may be an explosion accident.
The protection functions provided by the BMS workshop are used to prevent them.

Charge / discharge protection
Over-discharge: lead Li-ion batteries to damage and degrade.
Overcharged: Li-ion battery can cause an explosion. It is very dangerous!
Charger voltage protection
This protection function is used to make sure the charger voltage is within a reasonable range.
Charger's voltage is too low: batteries' power flows back to the charger.
Charger's voltage is too high: large voltage difference damages the charger and batteries.
Charge / discharge current protection
Charge current is too small: it needs to take a longer time for charging.
Charge current is too large: the batteries' temperature raises sharply and causes damaged.
Large discharge current: lead batteries to overheat and degrade.
Short-circuit protection
The protection system can interrupt voltage output immediately if a short circuit occurs during operation.
Temperature protection
If Li-ion batteries keep working at high temperatures, battery circling is reduced.
