In simpler words, the high voltage BMS is designed to ensure high voltage lithium-ion batteries'' safe, efficient, and reliable functionality. High voltage BMS is often used in large-scale energy storage systems. As power storage becomes more and more important, the role of high voltage BMS is becoming more and more obvious.
This protects the battery pack from too high or too low battery voltage, helping to prolong the life of the battery. The BMS also monitors the remaining capacity in the battery. It continuously tracks the energy going in and out of the battery pack and monitors the battery voltage. It uses this data to know when the battery is depleted and turn

General Removal Procedures 2.1 Safety Precautions and Before You Start Working on the EV • Make sure to wear your personal safety equipment and that it fits properly, is worn correctly
The slave board is capable of functions such as cell balancing, temperature and voltage monitoring. It receives task messages from the main BMS (master) and periodically sends back cell measurements. The slave
The overcharge protection function of the protection board is to monitor the voltage of the battery pack in real time. When it is charged to the top of the safe voltage range, it will cut off the power supply to prevent the voltage from continuing to rise, thereby playing a protective role. When charging, the protection board will monitor the voltage of each string of
In simpler words, the high voltage BMS is designed to ensure high voltage lithium-ion batteries'' safe, efficient, and reliable functionality. High voltage BMS is often used in large-scale energy storage systems. As power
If the BMS is not able to properly balance the cells in a battery pack, it can cause cell damage and even failure. It''s therefore important to ensure that your battery pack''s BMS has adequate BMS cell balancing protection capabilities. Make sure your BMS is enabled and perform this function properly to get the most out of your battery pack.

A battery pack includes a battery pack case, a battery pack connected in series and parallel, a battery management system (BMS), a wiring harness (strong & weak current), strong current components (relays, resistors, fuses, Hall sensors), etc.
The pack''s high output voltage also represents a risk to the driver, passengers, and any other persons involved in an accident. Adherence to relevant automotive functional safety legislation is crucial and another task on the list of requirements for the battery management system.

As for PHEVs and especially BEVs the battery pack accounts for the biggest part of the weight of the whole vehicle, the battery housing is designed in strong interaction with the design of the body of the car.
Depending on the location of the battery pack in the specific vehicle application, the casing is designed to withstand occurring crash loads. Hence the required crash performance of the battery pack substantially influences the design and especially the weight of the housing and the whole system.
As outlined in a previous chapter, it may be necessary to provide a peak power of, for example, 100 kW for electric vehicles (EVs). The term high voltage is defined for DC voltages above 60 V and AC voltages above 30 V (ISO 6469-3, 2011). The reason for using high voltages in a battery pack comes from the basic law of physics: (10.1) P = V ⋅ I
The cooling plates of the battery pack are an integral part of the housing and take over crash loads. Other interesting aspects are the usage of Kevlar, which is applied to the bottom of the casing to protect it from damage due to road debris and to prevent the intrusion of objects.
The massive electrification efforts happening in the automotive industry are driving the need to reduce the complexity of BMS by adding electronics in the junction box, while enhancing system safety. A pack monitor can locally measure the voltages before and after the relays, the current through the battery pack.
