Lithiumate™ - Distributed Li-Ion BMS controllers

These BMS controllers, together with Cell Boards, form a complete a Li-Ion BMS.

Description

Elithion offers a range of Li-Ion Battery Management System controllers to for the core of a Li-Ion BMS.

BMS controllers:
- Required
- Manage the battery
- Communicate with cell boards and with the rest of the system
- Available at the board level, or encased
High Voltage Front Ends:
- Optional
- Lets the controllers perform certain tests before turning on contactors
- May include an on-board current sensor
- Available at the board level, or encased
- Available in the same case as the controller

This table lists all the available products:

PN Controller HV Front End Enclosure Current sensor:
5, 20, 50, 100, 200 A Price Notes
2CN0000B ✔ - - * $ 240 Optionally, may be connected to an HV Front End through the CAN bus
2CN0000E ✔ - ✔ * $ 290
2CN0000H ✔ ✔ ✔ * $ 406 A BMS controller and an HV Front End are in the same enclosure. The HV Front End includes circuits that are connected to the Battery and are therefore at high voltage. Putting those circuits on a separate board improves safety in the BMS controller and reduces the chance of electrical noise interference to it.
2CN0xxxH ✔ ✔ ✔ ✔ $ 416
2HR0000B - ✔ - * $ 116
A Remote HV Front End:

Keeps the high voltage away from the BMS controller
Keeps any electrical noise away from the BMS controller
May simplify the layout of high voltage cabling
Communicates with the BMS controller through the CAN bus

2HR0xxxB - ✔ - ✔, 1 ea $ 126
2HR0xxxB - ✔ - ✔, 2 ea $ 136
2HR0000E - ✔ ✔ * $ 166
2HR0xxxE - ✔ ✔ ✔, 1 ea $ 176
2HR0xxxE - ✔ ✔ ✔, 2 ea $ 186

* An external current sensor, is required, unless the battery current value is already present on the CAN Bus.

Selector

Use this flowchart to select a combination of components for the BMS controller set, based on your system needs.

Controller selector flowchart.

The BMS controller must read the battery current through one of these methods:

The CAN bus: if the value of the battery current is already present on the CAN bus, neither a HV Front End nor current sensors are required
One or more current sensors

Valid combinations

This table shows the valid combinations of components for the BMS controller set.

Whether or not you want to place the HV Front End away from the controller
Whether or not you want to place the current sensor on the HV cable, or is the CAN bus already includes information on the load current.
Whether or not you need to detect the end of precharge or a loss of insulation
