2. Battery management system - Wikipedia

   en.wikipedia.org/wiki/Battery_management_system

   A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as SoH, and SoC), [1] calculating secondary data, reporting that data, controlling its environment, authenticating or balancing it.

3. SAE J1772 - Wikipedia

   en.wikipedia.org/wiki/SAE_J1772

   Seven car makers (Audi, BMW, Daimler, Ford, General Motors, Hyundai, Porsche, Volvo, and Volkswagen) agreed in late 2011 to introduce the Combined Charging System in mid-2012. [16] The first vehicles using the SAE Combo plug were the BMW i3 released in late 2013, and the Chevrolet Spark EV released in 2014. [17]

4. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   The Panasonic NiMH charging manual warns that overcharging for long enough can damage a battery and suggests limiting the total charging time to 10–20 hours. [ 22 ] Duracell further suggests that a trickle charge at C /300 can be used for batteries that must be kept in a fully charged state. [ 23 ]

5. 42-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/42-volt_electrical_system

   [1] 42 volts is an approximation of the output of the new standard's charging system. [2] The present nominally 12 V automotive electrical system usually operates around 13.8 volts, so 14 V is descriptive. Literature on 42-volt electrical systems often refers to systems powered with a 6-cell lead-acid battery as nominally 14 volts.

6. 48-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/48-volt_electrical_system

   A 48V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe without special protective measures.

7. Anti-lock braking system - Wikipedia

   en.wikipedia.org/wiki/Anti-lock_braking_system

   Piston Systems: The pressure release in this system is realized through the movement of a spring-tensioned piston. When pressure should be released, a linear motor pulls back the plunger piston and opens up more space for the fluid. The system was used for example in the ABS I (1988) and ABS II (1993) of BMW.
